Pots – Gardens Illustrated https://www.gardensillustrated.com Fri, 17 Mar 2023 08:16:04 +0000 en-US hourly 1 Auriculas: how to grow auriculas and the best auriculas to plant https://www.gardensillustrated.com/plants/spring/auriculas-how-to-grow/ Tue, 07 Mar 2023 14:55:19 +0000 https://www.gardensillustrated.com/?p=74833

Woottens, in the flat lands of Suffolk at Wenhaston, five miles from the sea, was founded in 1990 by Michael Loftus, who was much admired as a plantsman. In 2016, four years after he died, his widow sold the nursery to two women who, from working with Loftus, had absorbed much of his knowledge, and shared his particular interest in irises, pelargoniums, hemerocallis and auriculas.

Auriculas are fussy, and for these they have some help from Gillian’s partner Jenny Stafford – in the past, the propagation was done by Sandra Sutton, who bred more than 30 of Woottens’ own hybrids. After the polytunnel collapsed during a storm in 2018, it had to be reclad and it took a couple of seasons to rebuild the collection. In 2020, however, they bought the Drointon collection of 2,000 show auriculas, and now Woottens is one of the best places to buy auriculas.

What are auriculas?

In the 18th and 19th centuries, auriculas were among the most popular plants collected by members of the English Florists’ Societies, and they remain popular with collectors to this day. Although the alpine auriculas are generally robust enough to grow in borders, Luci and Gillian believe both show and alpine auricula types are best grown in individual pots, and perhaps displayed in a traditional Auricula Theatre, where the vast array of different flowers in wonderful colours can be fully appreciated.

How to grow auriculas

Root aphids have recently been a nuisance to growers of auriculas, so I wanted to learn how they manage their plants. Gillian says these picky alpines hate being too wet, but they also don’t like being too dry in summer, because root aphids thrive in dry conditions.

Dividing auriculas

Many growers divide their plants after flowering, but life on the nursery is too busy, so their plants are usually divided in July to August. When root aphids strike, it involves removing all the compost and then washing the roots with horticultural soap.

Feeding auriculas

The plants get a root feed high in phosphorous and very low in nitrogen in early February, and a potassium feed to encourage flowers a fortnight later and then every two weeks. Woottens use a compost that is 50 per cent peat substitute, 25 per cent grit or perlite and 25 per cent loam, such as John Innes, with some added slow-release fertiliser.

Where to grow auriculas

Auriculas grow in the crevices of rocks, so they do not like being overpotted. Ideally, they should be in a shady east-facing site, with protection from wet in winter.

Where to buy auriculas

If you are tempted to start your own auricula collection, look out for Woottens’ availability list, which is usually published on its website in February. You can order as soon as the list is published, for dispatch in March, but be quick, as this early release attracts lots of collectors and enthusiasts – last year’s list sold out within a week. Most years Woottens also holds an Auricula Open Day in late April.

How to propagate auricuas

The only way to reproduce an auricula true to its parent is by taking offsets from that parent. You can do this at any time while the plant is actively growing, but it is probably best to take offsets after flowering, while repotting.

• Begin by removing all the old compost from the roots thoroughly, and cleaning if there are any signs of pest or disease.

• Split the clumps if necessary or desired and repot. Any offsets can be easily teased off the main root (known on auriculas as the ‘carrot’) and potted up. Always make sure you have a section of both root and leaf to make a viable new plant.

• After division, pot into 7-9cm pots and feed the young plants with a high-phosphate feed to encourage strong root growth.

• Don’t overpot auriculas. This may lead to overwatering, with roots sitting in wet compost, when they need excellent drainage.

 

Top 16 auriculas to grow

Primula auricula ‘Cuckoo Fair’

© Richard Bloom

One of the Self group of auriculas that are the closest to the original auricula species, with petals of just one clear colour. Easily damaged and best grown in show pots. Bred by Pop’s Plants in 1996, it has deep-purple flowers and tall upright stems. 15-20cm. RHS H5, USDA 3b-9b.

 

Primula auricula ‘Weirdo’

Primula auricula ‘Gild Green’

© Richard Bloom

 

One of the Edge group of auriculas, which are distinguished by having an unusual edge to the flower petals. In this case flowers have a black body with a green edge. The cultivar name is thought to be an abbreviated version of ‘Geldersome Green No.2’, bred by Jack Ballard in 1970, and so-called because the original plant flowered, was named and then died. 15-20cm. RHS H5, USDA 3b-9b.

Primula auricula ‘Arwen’

© Richard Bloom

A plum-red cultivar that belongs to the light-centred alpine group that are strong growers and well-suited to growing in open borders. Petals fade from a dark colour to a lighter shade. One of a series named for Lord of the Rings characters, bred by John Radford. 15-20cm. RHS H5, USDA 3b-9b.

 

Primula auricula ‘Devons Road’

© Richard Bloom

 

A Fancy type of auricula, technically the rejects of auricula breeding (those that didn’t fit in with the stringent rules of the other groups were categorised as Fancy). It has a purple body and a thick white edge, and was bred by Henry Pugh in 2006. 15-20cm. RHS H5, USDA 3b-9b.

 

Primula auricula ‘Strand’

© Richard Bloom

A Stripe type with flowers that have stripes of red, bronze and white and the powdery markings known as farina on the petals. It was bred by Henry Pugh in 2003. 15-20cm. RHS H5, USDA 3b-9b.

Primula auricula ‘Stripey’

© Richard Bloom

 

An unusual Double auricula with small, finely striped mauve and cream flowers. Unusually for a Double auricula, it shows an open centre. 15-20cm. RHS H5, USDA 3b-9b.

 

Primula auricula ‘Sandhills’

© Richard Bloom

A floriferous, gold-centred alpine with flowers that are dark maroon with a narrow edge. A seedling of P. auricula ‘Sirius’, it was bred by Arthur Delbridge in 1989, and named after a local sand quarry near the raiser’s home. 15-20cm. RHS H5, USDA 3b-9b.

Primula auricula ‘Woottens Ragged Canary’

© Richard Bloom

 

Another Fancy type, this one bred by Woottens in 2008. Lightly fragrant, it has attractive multi-coloured flowers that are yellow with a green edge. 15-20cm. RHS H5, USDA 3b-9b.

Primula auricula ‘Woottens Advent’

© Richard Bloom

A Border type bred by Woottens in 2008. A cross between Primula auricula ‘May’ x Primula auricula ‘Old Yellow Dusty Miller’, it has soft purple flowers. 15-20cm. RHS H5, USDA 3b-9b.

Primula auricula ‘Minty’

© Richard Bloom

A purple cultivar, with pale, mint-green stripes from the Stripe group, one of the oldest categories. Bred by Derek Parsons in 2006. 15-20cm. RHS H5, USDA 3b-9b.

 

Primula auricula ‘Brick Lane’

A Stripe type with flowers striped deep and pale purple. Bred by Derek Parsons in 2006. 15-20cm. RHS H5, USDA 3b-9b.

 

 

Primula auricula ‘Old Irish Scented’

© Richard Bloom

One of the Border group that generally resemble the species Primula hirsuta, although this dusky yellow with a frilled edge is very different in appearance. It was discovered in the gardens of Lissadell House in Ireland. 15-20cm. RHS H5, USDA 3b-9b.

 

Primula auricula ‘Bright Ginger’

© Richard Bloom

 

A Self type with striking golden orange colour. Thought to be a Tim Coop seedling, named by Brenda Hyatt in 1997. 15-20cm. RHS H5, USDA 3b-9b.

Primula auricula ‘Helen Barter’

How to attract wildlife to your garden https://www.gardensillustrated.com/garden-advice/how-to/attract-wildlife-garden/ Wed, 01 Mar 2023 10:47:54 +0000 https://www.gardensillustrated.com/?p=7950

British gardens are key habitats for bees and butterflies and gardeners can do a lot to attract wildlife and help the decline in pollinators. An increase in beneficial insects can mean fewer pests, too. Our guide to attracting wildlife into the garden gives advice on ecological design, the best plants for pollinators and stylish container displays for beneficial insects.

If a plant is listed as pollinator friendly, it means it will provide nectar and pollen for pollinating insects such as bees and butterflies. It also refers to the shape of the flower and how the plant has been grown. Pollinator-plants will often have trumpet-shaped blooms or single flowers for insects to crawl into and land on, and mostly free from pesticides. Look out for the Royal Horticultural Society’s Plants for Pollinators symbol at garden centres and plant nurseries if you want reassurance that you’re buying the best plants for garden wildlife.

Here is our guide to attracting wildlife into the garden, with advice on pollinator-friendly plants and how to improve wildlife habitats through considered garden design.

How to attract wildlife to your garden

There are lots of ways to encourage wildlife into the garden, from simply planting a range of different flowering plants, to building an insect hotel or introducing a bird feeder. Here are a few ideas to get you started.

Grow a range of bee and butterfly-loving plants and flowers

  • Make sure the plants have different flower shapes to invite a whole host of beneficial insects into the garden. Salvias or Verbena bonariensis attract butterflies and bees, and trees and evergreen or flowering shrubs that will provide shelter for birds. Try to leave a patch of nettles, as they are beneficial as food to caterpillars. Here’s our list of the best plants for bees, and the best plants for butterflies. 

Leave seeds head up over winter for insects

  • In winter, leave architectural seed heads for birds to feed on and plants with strong stems are perfect for hibernating beetles and solitary bees.

Look for plants that bees will love – full of pollen

  • Avoid sterile plants with little or no pollen. These are often double flowered cultivars.

Build a pond

Make space for insect hotels and bird boxes

Hedgehog houses, insect hotels and bird boxes are all easy to add to the garden and are invaluable to hibernating wildlife and nesting birds. Don’t miss our guide on how to build a bug hotel, and here are our favourite insect hotels to buy.  Bird boxes are a great way to get birds to stick around too. 

 Plant for the birds

Planting a hedgerow a bird can eat could get them through winter. We have a great guide on the best plants for birds. 

Make sure you plant with biodiversity in mind

  • Enhance biodiversity. Don’t tidy your garden too much. In autumn, leave all plants and leaves that have died off and don’t start clearing them up until February. The dead plant material offers protection against frost and shelter for insects and other small animals. Most insects like cool, moist conditions, but bees prefer a sunny spot.

 

Never use pesticides

If you’re looking for tips on how to control things like slugs, our piece from organic grower Poppy Okotcha explains how you can do that without nasty pesticides. 

 

Aim for ladybirds

  • There are several pollen plants that attract ladybugs that tend to be yellow and white, such as Angelica, Cosmos and Fennel.
  • Plant decoy plants that will attract aphids away from your desired bug free plants until the ladybugs remove them for you. Aphid attracting decoy plants could include: Early Cabbage, Marigold and Radish.

Ladybugs eat two things: insect pests and pollen, and there are several pollen plants that ladybugs like, including: Calendula, Chives, Cosmos and Marigold.

Attracting bats to your garden

Did you know that attracting bats to your garden is one of the safest and most efficient methods for natural insect control? One little brown bat can eat 1,200 insects per hour.

A great bat attracting method is to build a bat house to provide a warm cosy shelter for the creatures. Since bats tend to set up colonies in the early spring, building a bat house is the perfect winter project! Some tips are:

  • Use a rough, nontoxic wood (such as plywood or cedar) to make your box. The rough surface will make it easier for bats to climb in and out of the house.
  • Place in a warm, sunny position for warmth
  • Keep it close to a freshwater source (pond, stream)
  • Support on a pole or the side of a building.

The key to attracting bats to your garden is to plant night-scented flowers, such as Yucca and Evening Primrose.

Attracting frogs to your garden

Attracting frogs to your garden is beneficial for the welfare of your plants. Frogs make great insect killers so why not attract some garden frogs to help with those little pests.

  • Build toad houses – overturned flower pots buried lightly in the soil make great shelters.
  • Avoid using pesticides in your garden. Frogs are sensitive to chemicals so use natural sources of nutrients in your garden such as compost.
  • Keep pets away from the part of the garden set up for attracting frogs.

Toads and female frogs usually spend winter on land, under rockery stones (or in a log pile). Recommended rock plants are: Aubretia, Hardy Geraniums and Sedums.

Wildlife-friendly container display

If you want your garden to benefit pollinating insects like bees and butterflies but worry your garden isn’t big enough for swathes of planting, consider creating a pot display. Containers planted with plants that attract wildlife suit a garden of any size. Try this gorgeous example.

 

The best seed heads for winter structure

Seedheads glistening with frost play an important part in bringing structural winter interest to the garden as well as providing food for birds and insects. For our recommended list of the best seedheads to create and eye-catching display in winter, click here.

 

Appreciate spiders in the garden

A healthy spider population will help reduce pest insects and should be welcome in any garden. Spiders obviously make no distinction between pests and helpful insects like hoverflies and bees, but they help maintain a natural balance wherever they are. Find out how to appreciate the spiders in your garden.

 

Improve your soil

No-dig gardener Charles Dowding explains why caring for the soil in your garden is just as important as caring for the plants you grow in it. Nurture your soil and you nurture the helpful organisms living in it, such as earthworms and beneficial fungi and bacteria.

Pot-et-fleur: a display built around aspidistra https://www.gardensillustrated.com/plants/pot-plants/pot-et-fleur-aspidistra-display/ Sat, 11 Feb 2023 11:32:41 +0000 https://www.gardensillustrated.com/?p=18164

The Victorians loved to show off, and table centrepieces became increasingly extravagant throughout the 19th century, often displaying a cornucopia of newly introduced houseplants teamed with exotic blooms and fruit. I wanted to capture a little of that dark and moody flamboyancy against the rich olive green of this wall. The arrangement was built around an aspidistra, the epitome of Victorian houseplants, combined with a selection of deep-green plants with similar and contrasting leaf textures.

Pot et fleur with aspidistra How to achieve the look

A glazed Victorian wash bowl, is ideal for this flamboyant display. It has no drainage holes, so won’t leak on to furniture, but will need careful watering. To begin, I lined the bowl with expanded clay pellets to absorb excess water then added a propriety houseplant compost mixed with extra charcoal. I placed the houseplants in the compost but kept the cheese plant (Monstera deliciosa) in its own pot for ease of removal, as it will quickly outgrow the display. Finally, I sank four thin-necked glass vases in the gaps, before top dressing with additional clay pellets.

The aspidistra copes well with shade, as do the other houseplants, inlcuding x Fatshedera lizei ‘Pia’, a cross between Fatsia japonica and Hedera helix. I placed two trailing peperomia at the front of the bowl to cascade over the lip. For foliar contrast I added a maidenhair and an asparagus fern.

The clean lines of the polygonatum’s tall, arching stems embellished with pendent flowers sits perfectly above the fading flowers of Helleborus x sahinii ‘Winterbells’, which take on a greener hue with age. The ridged, clean stems of Equisetum hyemale add a vertical contrast to the composition.

The arrangement needs a spot away from direct sunlight and regular misting. Overwatering is often the cause of a plant’s demise, so always check the compost before watering. If you don’t trust your finger use a water indication stick. Houseplants benefit from a weekly balanced liquid feed in the growing season, but too much nitrogen can lead to weak sappy growth.

Equipment you’ll need

  • Traditionally, ornate punch bowls or soup tureens were used to hold elaborate, pot-et-fleur designs but any container could be adapted for a more contemporary approach including terracotta and ceramic bowls, willow baskets, glass aquariums or metal boxes, but if it’s not water tight, you’ll need to take care to protect the surface it sits on.
  • Within the main container you can use any sealed vessel to hold the cut flowers but if it will be partially visible, opt for more attractive containers, such as old ink pots or vintage glass bottles that have a wide base and thin neck. Glass test tubes are a good option but take care when burying them in case they break, and always secure safely.
  • A pin holder is an excellent way of accurately securing heavy stems. These discs of metal spikes are much relied on in the practice of ikebana, the Japanese art of flower arranging, lending a more naturalistic feel to an arrangement. I also use several heavy, semi-spherical glass frogs to hold flowers and branch stems. Be sure to attach both of these securely to the base of the vase with floral putty or tape before arranging. A length of wide-gauge chicken wire scrunched into a loose ball will do a similar job. Sharp scissors or secateurs are also essential bits of kit; thorn and leaf strippers are useful too.
  • Before you start arranging your cut flowers, snip off the ends of picked stems and remove any foliage that will be below the water level and leave in deep water for up to 24 hours. Regularly topping up water levels or changing the water entirely every couple of days will help the arrangement last longer as air locks and bacteria will quickly cause a stem to wilt.
  • Houseplants are easily killed through overwatering, so using hydroleca clay expanded pellets will not only add an attractive finish to the container, they will also absorb extra water, slowly releasing it as the compost dries out. They help maintain a humid microclimate around the plants when wet and even out fluctuations in the surrounding temperature. Activated charcoal is another useful addition to the growing medium as it reduces the build up of impurities minimising odours.
  • Propriety brands of houseplant potting compost with an open, free-draining mix should be sufficient for most growing needs but you can improve drainage by adding perlite, vermiculite, horticultural sand or grit. A top dressing of decorative gravel, clay pellets or moss will also reduce water loss.
  • A slim watering can with a long narrow spout for small spaces is ideal for these displays, but misting is an excellent way to maintain the humidity around plant leaves.

How to grow hyacinths: a guide to this easy-to-grow bulb https://www.gardensillustrated.com/garden-advice/how-to/growing-hyacinths/ Tue, 07 Feb 2023 10:01:26 +0000 https://www.gardensillustrated.com/?p=100345

Popular for spring displays, hyacinths bring a real splash of colour to house and garden early in the gardening season. Available in a range of shades including blues, white, pink, purple, yellow and deep red. Their scent adds to their appeal too. They flower spikes are made up of a multitude of closely packed florets.

How to grow hyacinths

Hyacinths are bought as bulbs in autumn and are easy to grow. When choosing your hyacinths to buy you will notice that some are sold as ‘prepared’. These are the ones to buy if you want your bulbs for growing indoors to bloom around Christmas or in January. Prepared bulbs have already been treated to a period of cold, which stimulates production of the hormones required for stem extension and so brings them into growth earlier. For later flowering or growing in the garden, normal, non-prepared bulbs are fine.

When to plant hyacinth bulbs

Plant your hyacinth bulbs in autumn. They will then flower around March to April. For prepared bulbs for growing indoors, you should plant these a little earlier and allow a good 10-12 weeks before expecting them to be ready to flower. For Christmas or winter blooms, for example, plant in August/September.

How to plant hyacinth bulbs

Planting hyacinth bulbs in the garden

• Hyacinths will grow in any good, well-drained garden soil and perform well in a range of situations including borders and rockeries. They need some moisture to grow and flower properly but avoid boggy areas where they may rot. A drier situation is preferred when the leaves have died back and they are dormant in summer.

alperti/REDA&CO/Universal Images Group via Getty Images

• Hyacinths prefer a sunny position although will be fine in semi-shade where you are happy to only have a one-year display (they won’t have stored enough energy for a good second year’s showing).
Plant bulbs in late September – October. Plant each bulb, pointed end upwards, 10cm deep. Leave a gap of at least 8cm between each bulb.
• To improve drainage, you can add a small handful of grit to the bottom of the planting hole.
• Autumn-planted bulbs will flower in March to April.

How to grow hyacinth indoors

• Use prepared bulbs for best results – these are widely available at garden centres.
• Choose a container big enough for 3-5 bulbs and deep enough for good root growth.

• Use multi-purpose, peat-free compost. You can also use bulb fibre compost.
• Put some crocks of gravel at the bottom of the pot to help drainage.
• Plant your bulbs so that they aren’t touching and their tips are just showing above the surface of the compost.
• Place your pot somewhere cool and dark – such as in a cupboard or shed – and leave for around 10 weeks, checking periodically to ensure it is kept moist (but not wet). After about 10 weeks, good roots should have developed during which time the roots will develop and shoots will begin to emerge.
• Once the shoot is around 3cm, bring the pot out into cool light conditions.
• In another three weeks you should begin to see some colour developing in the forming bud. You can now bring your pot into the house, or if already growing indoor, into a light warm room.
• Be aware that you may well need to stake your flowers as they can get a bit top heavy. A network of twigs works well for this. Gently push them into the soil around the bulbs and arrange so that the twigs give support.
• If you planted your prepared bulbs in August/September you should have displays in time for Christmas. Or better still, time your display for the darker days of January.

Here’s more on forcing bulbs indoors

The best hyacinths to grow

Hyacinths come in three types – single hyacinths with single florets, double hyacinths, where each floret has a double ray of petals, and multiflora hyacinths that have a looser arrangement of florets on multiple flower stems. Their looser appearance can make them easier to grow in the garden where a less-formal look is preferred. The singles and doubles make good displays for growing in pots indoors.

Grape hyacinths, which although there is a similarity in their form are a completely different species – Muscari.

What are bulb vases and can I grow hyacinths in them?

Bulb vases as a lovely way to grow single bulbs. They are glass vases with a narrow, splayed neck the you place the bulb on to – without it falling through into the vase. Fill with water to just below the base of the sitting bulb. Place in a dark cool spot, such as a cupboard and check periodically to ensure the water is kept topped up and that the roots are beginning to grow down into the vase and the shoot is emerging. Once the shoot is 3-4cm in height, bring the vase into a sunny warm room and the bulb will soon flower.
If the water gets cloudy, carefully lift the bulb off and refresh the water. You can also add charcoal to water to help keep it fresh.

Find out more about forcing bulbs

What to do with hyacinths after flowering?

Deadhead spent flowers.
• Feed the remaining leaves regularly with a high-potassium liquid plant food until the leaves start to yellow.
• The leaves will eventually die back completely and your bulb will be left to re-grow the following spring.
• Hyacinths can re-flower for a few years, but displays may diminish each time.
• Once your pot-grown, indoor flowers have finished, you are best to plant the bulbs out into the garden. You should get some re-flowering the following year but it’s unlikely to be as fulsome as using fresh bulbs.

The art of pot-et-fleur: combining houseplants with cut flowers https://www.gardensillustrated.com/plants/pot-plants/pot-et-fleur-flower-arranging-display/ Mon, 06 Feb 2023 12:58:21 +0000 https://www.gardensillustrated.com/?p=18123

I love using wildflowers in naturalistic floral arrangements and grow as many as possible in my own garden so that I am free to pick as desired. This arrangement was inspired by a walk down my local country lanes in May where the hedgerows are lined with billowing clouds of cow parsley, Anthriscus sylvestris, exuding a light and airy feel. I’ve combined this iconic umbellifer with several Adiantum ferns and a trio of blues from the borage family to add some sparkle to the mix.

Pot et fleur how to achieve the look

This handsome wooden crate houses ten chunky soda bottles, but for this display I replaced seven of them with maidenhair ferns in 1L pots and three with cut flowers in glass vases, anchoring the arrangement with a row of Victorian clay ink pots.

A selection of tall, cow parsley stems adds height, and I picked those with the darkest purple stems to match the rose-flushed buds of the Clematis montana. These provide a link to the almost-black stems of the maidenhair fern, whose fresh virescent tones add a sense of depth to the display.

Green alkanet, Pentaglottis sempervirens, and Siberian bugloss, Brunnera macrophylla, provide a drift of bright blue that is subtly enhanced by the chalkier blue of forget-me-not, Myosotis sylvatica. This arrangement will last nearly two weeks in a cool conservatory out of direct sunlight with regular misting and changes of water in the vases. The ferns appreciate high humidity and should be kept well watered during the growing season.

All the flowers used in this display are prolific self-seeders so need careful management to stop them taking over your garden. The hairy leaved alkanet can be found flowering along woodland edges so is happy in part shade while the bugloss makes a great groundcover plant. I cut both hard back in June and July, after their initial flowering to refresh and keep them in check. Myosotis sylvatica also copes well with shade, readily seeding about but is easy to pull out where not required.

  • Traditionally, ornate punch bowls or soup tureens were used to hold elaborate, pot-et-fleur designs but any container could be adapted for a more contemporary approach including terracotta and ceramic bowls, willow baskets, glass aquariums or metal boxes, but if it’s not water tight, you’ll need to take care to protect the surface it sits on.
  • Within the main container you can use any sealed vessel to hold the cut flowers but if it will be partially visible, opt for more attractive containers, such as old ink pots or vintage glass bottles that have a wide base and thin neck. Glass test tubes are a good option but take care when burying them in case they break, and always secure safely.
  • A pin holder is an excellent way of accurately securing heavy stems. These discs of metal spikes are much relied on in the practice of ikebana, the Japanese art of flower arranging, lending a more naturalistic feel to an arrangement. I also use several heavy, semi-spherical glass frogs to hold flowers and branch stems. Be sure to attach both of these securely to the base of the vase with floral putty or tape before arranging. A length of wide-gauge chicken wire scrunched into a loose ball will do a similar job. Sharp scissors or secateurs are also essential bits of kit; thorn and leaf strippers are useful too.
  • Before you start arranging your cut flowers, snip off the ends of picked stems and remove any foliage that will be below the water level and leave in deep water for up to 24 hours. Regularly topping up water levels or changing the water entirely every couple of days will help the arrangement last longer as air locks and bacteria will quickly cause a stem to wilt.
  • Houseplants are easily killed through overwatering, so using hydroleca clay expanded pellets will not only add an attractive finish to the container, they will also absorb extra water, slowly releasing it as the compost dries out. They help maintain a humid microclimate around the plants when wet and even out fluctuations
    in the surrounding temperature. Activated charcoal is another useful addition to the growing medium as it reduces the build up of impurities minimising odours.
  • Propriety brands of houseplant potting compost with an open, free-draining mix should be sufficient for most growing needs but you can improve drainage by adding perlite, vermiculite, horticultural sand or grit. A top dressing of decorative gravel, clay pellets or moss will also reduce water loss.
  • A slim watering can with a long narrow spout for small spaces is ideal for these displays, but misting is an excellent way to maintain the humidity around plant leaves.

House plant display: creating the perfect stylish display https://www.gardensillustrated.com/plants/planting-ideas/perfect-houseplant-display/ Wed, 11 Jan 2023 09:00:53 +0000 https://www.gardensillustrated.com/?p=24230

When planning house plant arrangements, keep plants with similar light requirements together. These exotics, which we cultivate in the conservatory and bring into the house when they reach their prime, have been positioned to take advantage of the intermediate morning light next to a sitting room window.

How to arrange this house plant display

© Jason Ingram

 

This position avoids the intense midday sunshine that may scorch the foliage. It’s a temporary display, and when the plants begin to look jaded they are returned to the conservatory and replacements found. The orchids take this upheaval in their stride, as do the ferns, and require little more than a light daily misting.

It is vital to avoid crowding them too closely together, otherwise, the display can look congested. Position the larger plants first, work from the back to the front, and try to consider the appearance of both flowers and foliage.

Best indoor pots to buy

Bergs Potter Plant Pot

For a traditional look, try one of these smart pots. They come in Emerald Green or Yellow Amber, with a glossy hand-applied glaze. You can choose the dimensions to suit your space, as these pots come in two sizes: 14cm(H)x16cm(W) or 16cm(H)x18cm(W).

 

LSA Canopy Recycled Self-Watering Planter

A low-maintenance and visually striking choice, the LSA Canopy self-watering planter has a cotton wick leading up from a water chamber at the bottom to keep the soil above moist. The developers created it in partnership with the Eden Project, and it’s made from 100% recycled glass and boxed in recycled and recyclable packaging.

Marquis & Dawe Round Rattan Zinc Lined Planter

An attractive rattan planter is a great choice for any space with rustic or country style. This one is handmade by Marquis & Dawe, and comes complete with a zinc insert to keep moisture inside. It has a diameter of 43cm, but it’s relatively shallow, at 16.5cm, so it would make a fantastic centrepiece on a coffee or dining table.

Oliver Bonas Gold Metal & Mango Wood Plant Pot Large

Adding warmth to a room is easy with this golden plant pot from Oliver Bonas. With a clean and minimal design, it has a hammered aluminium planter and sits on lightly-stained mango wood legs.

This pot is 27cm tall and 26cm across, so it should be able to accommodate large plants and small trees.

XLBoom O-collection Planter, Black, Large

With its hoop-shaped design, this planter from XLBoom would make a simple yet eye-catching addition to any home. The top of the hoop reaches 60cm in height, and the whole planter has a depth of 30cm.

If black isn’t your ideal choice, why not opt for the white version?

Withington Pot

If you love homeware with a rustic, antique-y look, you might like the Withington range of pots. Reminiscent of vintage marmalade jars, they have a simple yet sturdy construction. They’re also handmade, and finished with a crackle glaze with elements of white, grey, brown and blue.

You’ll get a choice of three sizes: 10cm, 12.5cm or 15.5cm in height.

Large Terracotta Plant Pot

Suitable for use both indoors and outdoors, this large plant pot is a versatile planter to keep at home. It’s made in Portugal entirely from terracotta, and it’s finished with neutral colouring, so it should fit nicely into most décor schemes.

This pot is 21.8cm tall, but there’s also a smaller option, which has a height of just 16cm.

Layered Cement Planter

Characterised by its neutral colour tone and intricately layered cement finish, this pot will add subtle texture to a room. It has a height of 12cm and a diameter of 16cm, so it’s a good size for most house plants, but its bowl-like shape should look particularly good with leafy and trailing varieties.

Set of Three Terracotta Pots in Basket

Another great option for homes with a vintage aesthetic is this set of three rustic terracotta pots. They’re held together neatly with an attractive wire structure, reaching a total length of 37cm. Meanwhile, each individual pot can hold up to 0.3L of soil.

Woven Hanging Plant Pot

You can draw the eye up in any room with beautiful hanging planters like this one from Garden Trading. It’s constructed with seagrass, but there are two other similar styles made from jute available – and all have an internal PVC lining to contain any water drips.

Ferns and trailing plants look especially great in hanging pots, creating a rural, breezy look in your home.

 

Two Textured Standing Planters

If you’re after something special, this pair of burnished gold planters might be the ideal choice. They’re constructed from aluminium and have little tripod legs underneath to keep them off the ground.

The set comes with a small pot, reaching 25cm in height, and a larger planter, which is 29.5cm tall.

H&M Large Mango Wood Plant Pot

H&M’s 100% wood plant pot brings warm tones, and it would look just as good in modern, minimalistic décor schemes as it would with traditional and neutral styles. It reaches 18cm in height, so it’s a good size to add to most table tops and furniture items.

Peperomia: How to grow and care for the house plant https://www.gardensillustrated.com/plants/pot-plants/house-plant-peperomia/ Tue, 10 Jan 2023 10:50:43 +0000 https://www.gardensillustrated.com/?p=14727

Peperomias are not wildly thrilling, but they do have a certain flair,’ writes Tovah Martin in her book The Unexpected Houseplant. Talk about damning with faint praise. She does have a point. Peperomias lack the imposing physicality of a 3m Monstera deliciosa embracing a moss pole, or the peacock patterning of a colourful Calathea, but I adore them for the sheer variety of leaf textures and for their diminutive size. For those without floor space for expansive specimens, peperomias are compact enough to house a sizeable collection on a modest shelving unit or windowsill.

How to care for peperomia

The different types of peperomia

Sally Williams, who holds the National Collection of Peperomia, has a plant room packed with 500 peperomias to tend while her Peak District garden is hidden under a freezing, white blanket of snow. There are familiars, such as the radiator plant (Peperomia caperata), which has crinkled leaves like toes after a long bath, and the watermelon peperomia (Peperomia argyreia) with heart-shaped glossy leaves draped in silver stripes, but I’m drawn to some rarities, too. One with foliage the colour and texture of toad skin is labelled Peperomia hutchisonii, while lifting a misty bell jar reveals a mass of minute leaves strung on the thread-like stems of Peperomia bangroana.

Where are peperomia from?

Sally’s collection demonstrates the diversity and scale of the Peperomia clan. Attempt to discover something seemingly simple, such as how many species are in the genus, and the answer varies from 1,300 to 1,600. Matt Candeias, a botanist and fellow Peperomia lover, tells me that Peperomia is an ancient group of plants that has evolved to thrive in a wide range of environments around the world, with concentrations in Central and South America and in Africa. Why does all this matter to you and me, tending a cluster of watermelon leaves or untangling the stems of a string of turtles (Peperomia prostrata)? Finding out about where your Peperomia hails from helps inform how you care for it.

Best conditions for Peperomia

The vast majority of peperomias you’ll find unhelpfully labelled merely as ‘foliage plant’ in your local supermarket or DIY store grow as epiphytes in rainforests, clinging to clefts in a tree where they enjoy humid air and dappled light. These – including rosette types, such as the watermelon peperomia, and trailers, such as the cupid peperomia (Peperomia nitida) – have modest rootballs and store water in their fleshy stems and leaves. Root rot is the peperomia’s number one enemy: know this, and you’ll find them among the most easy-going and undemanding houseplants you can grow.

How to care for Peperomia

Best soil for Peperomia

Sally raises her plants in terracotta pots, planted in an airy mix of two parts peat-free, general-purpose potting mix, one part orchid bark and one part perlite.

How often to water Peperomia

Sally also keeps the air moist by misting – watering just once a month. Succulent species, such as Peperomia columella, Peperomia ferreyrae and the toadlike Peperomia hutchisonii, generally hail from high altitudes in South America, particularly Peru, adapting to arid conditions and dry air by folding their leaves in half like a taco when water is in short supply: these prefer an even more free-draining, gritty mix and will thrive in a sunny, south-facing window. Rare trailing species, such as Peperomia bangroana, require really high humidity and do best creeping around in a shady, sealed terrarium.

How to propagate Peperomia

The key to successful Peperomia propagation is to know whether your specimen will root from a section of stem, a leaf petiole cutting or even, miraculously – from a section of leaf. The general rule is that rosette-forming types will propagate from a leaf petiole cutting, while trailing peperomias will grow roots from a length of stem.

  1. Take a clear plastic pot with a tight fitting lid – a recycled hummus pot is ideal.
  2. Place a trickle of water so the bottom is just covered and then add the leaf or section of stem, curling it around the edges of the pot if necessary.
  3. Place the lid on and leave on a bright windowsill out of direct sun.
  4. Check every week until roots and shoots have appeared, then pot up into gritty compost.

This method works for most peperomias except succulent types such as Peperomia columella, which can be rooted straight into gritty compost instead.

String of pearls plant: how to care for your Curio rowleyanus https://www.gardensillustrated.com/plants/pot-plants/string-of-pearls-houseplant/ Tue, 10 Jan 2023 08:50:37 +0000 https://www.gardensillustrated.com/?p=23976

Of all the succulents, the string of pearls plant (Curio rowleyanus) is one of the most distinctive and most sought after, adored for its cascade of wiry stems festooned with tiny spherical leaves that look like peas (or beads or pearls, if you are feeling poetic). But if I could do one thing in the service of horticulture, it would be to end the tragic deaths of string of pearls plants at the hands of their owners.

Within weeks, the pearls are shrivelled or turned to mush, and the befuddled owner just can’t fathom why – they watered their plant at the same frequency as their other succulents, placed it in the same sunny windowsill, and yet it will not thrive.

Where the string of pearls plant originated

The string of pearls plant, or Curio rowleyanus (you may recognise it under its previous name of Senecio rowleyanus) is found only in the Karoo shrubland of South Africa’s southern cape although other species are found as far north as Namibia. Despite its characterisation as a trailing plant in cultivation, in the wild string of pearls forms a mat on the ground, often growing beneath and over shrubs and other plants or lodging in cracks in rocks, rooting along its stems where it can find a suitable spot.That provides an important clue as to where things go wrong with this plant in the home: it is adapted to grow in sharply drained soil that is low in humus.

How to care for string of pearl plants

 

When bought from a garden centre or online shop rather than a specialist grower, string of pearls usually arrives in a plastic hanging pot with a built-in saucer, planted into regular house plant compost (if you are particularly unlucky, this will already be sopping wet). It’s not long before poor drainage and spongy soil allows water to build up around the roots, and the plant will start to protest.

Make sure the string of pearl plants are in gritty, well-drained compost

It’s wise to repot plants as soon as possible into a gritty mix of a third to a half grit or perlite and a similar quantity of John Innes No.2. I find a terracotta pot rather than a plastic one helps to keep the roots happy.

When to water string of pearl plants

With these measures in place, plants can be generously watered once a week in summer without risk of damage. From November onwards, cooler temperatures combined with minimal watering keep string of pearls ticking over until spring.

Give your string of pearl plant lots of light

What about light? In the wild this plant doesn’t usually grow completely exposed to the sun, but of course the intensity of the light is hugely greater there than the average sunny windowsill in a British home. My string of pearls plant grows contentedly on a high shelf in my glass-roofed, north-facing sunroom, where it gets lots of bright light: plants may need some shading if they are grown in a greenhouse or outside during the hottest months. The cream-striped variegated form seems more susceptible to sun exposure, so take extra care if you are lucky enough to own one of these.

It seems churlish not to mention the flowers. Small, white inflorescences appear along the stem in summer, making their presence known via a cinnamon scent rather than dramatic looks. They are, however, most likely the only way you’ll ever know that string of pearls is a member of the daisy family (Asteraceae).

How to propagate string of pearls

Once you’ve cracked caring for Curio rowleyanus, you can play Lady Bountiful and root some cuttings for admiring friends. The simplest way to do this is simply loop the stems back on to the surface of the compost until they root and can be snipped away.

Once your plant is happy, and you are no longer afraid to look at it sideways in case it keels over, it is worth examining it more closely. Like many succulents, the string of pearls plant has found a way of adapting to its arid environment through its leaves. Reach back to maths class at school and you may recall that a sphere has the lowest surface area to volume ratio of any shape. By having spherical leaves, string of pearls can store the maximum amount of water possible. At the same time, there’s less surface area through which water loss (transpiration) can occur, and less leaf exposure to the midday sun, reducing the prospect of the leaf getting frazzled by the heat.

But what about photosynthesis, you may wonder – surely reducing the surface area of the leaf means string of pearls won’t receive enough light? The plant has another clever trick for that. Each leaf contains a darker strip that’s visible when held up to the light. This is an epidermal window, which seems to work by allowing light to pass into the inner tissues of the leaf where photosynthesis can occur. I write ‘seems’ as botanists are still investigating exactly how these windows function. These fascinating plants may yet have more secrets to reveal
