Very few flowers offer such a vivid spectacle as zinnias. Available in a broad spectrum of colours (except for blue), they jostle for joy in a spectacular Latino parade. These highly decorative and irrepressibly cheerful daisies have their roots in the rocky hillsides of native northern Central America, Mexico and southwestern USA. Hybridisation and rigorous re-selection has tamed and transformed the straggly wild zinnia into dramatic garden plants with bigger, fuller, flowers of singles, doubles, semi-doubles and pompoms in myriad tones.

Around 20 species of Zinnia are found in the wild, mainly annuals but with some perennials and shrubs. The genus is named after the 18th-century German botanist Johann Gottfried Zinn, who first described the flower. Zinnias have their own style with rich green foliage setting off fiery daisy flowers and reptilian, prominently scaled flower buds.

Zinnia ‘Benary’s Giant Orange’

Zinnias: everything you need to know

How tall do zinnias grow

The most striking are the old-fashioned, tall, large-flowered forms bred from the wild Zinnia elegans – a coarse plant from Mexican deserts, at 1m tall with single purple flowers 5cm across. All make excellent cut flowers lasting several days. Zinnia Giant Double Mixed is a stirring mix of tall, double and semi-double flowers, up to 11cm across, blended in garish shades of yellows, pinks, oranges, and deep reds. Zinnia Dahlia Flowered Mixed is similar (if not identical).

The most striking of all the large-flowered cultivars are the Zinnia Benary’s Giant Series, which appear in a range of vivid single colours. Plants are robust on thick branching stems growing 1.3m tall and 0.5m wide. ‘Benary’s Giant Salmon Rose’, ‘Benary’s Giant Lilac’, ‘Benary’s Giant Deep Red’, ‘Benary’s Giant White’ and ‘Benary’s Giant Orange’ are just a selection that I grow. Other colours are available from rich carmine red to yellow but seed is difficult to source in the UK, with the full range available only from the USA.

Zinnia ‘Profusion Orange’
Sharon Pearson

Zinnia Giant Cactus Flowered Mixed is also tall at 1m and has full flower heads packed with gently quilled petals. The blend comes in six or seven colours and works well in mixed borders although sometimes plants are of ragged appearance.

Recent breeding efforts have favoured dwarfing, producing ungraceful stocky plants with large flowers. Here impact seems to have conquered grace, but a few of the large-flowered, short-stemmed hybrids still retain the charm and character of their parents. For example, plants of the Zinnia elegans Dreamland Series are just 40cm high and not overly squat. Their plump double flowers are most effective at the front of borders or in pots. Coral, ivory, pink, yellow and rose and a mixture exists, but ‘Dreamland Scarlet’ in fiery orange and ‘Dreamland Red’ in deeper red, both with yellow centres, inject intense colour without sacrificing much space.

How to grow zinnias

Sowing zinnias

Zinnias are hot-weather plants that crave heat and love sun. Little is gained by starting them early as cool temperatures could delay planting out.

  • In the UK, sow zinnia seeds in mid-May under glass. Germination takes as little as three days if the temperatures are high.
  • Prick out seedlings into small pots or plug trays as soon as they are large enough to handle and nurture under glass before gradually hardening them off.
  • Root congestion can be a setback, so plants should be moved on to the next pot size if they root through before outside temperatures are high enough for planting.
  • In southeast England we plant them in the first or second week of June, when night-time temperatures are generally above 10°C. As they hate root disturbance, zinnias are better sown direct in hotter climates as they germinate and thrive without being checked.
Zinnia ‘Benary’s Giant Lilac’

How to care for zinnias

Zinnias thrive in light, rich, well-drained soil. They will tolerate drought but need water while establishing in order to develop a root system. Avoid excessive watering as this will reduce the risks of fungal diseases such as powdery mildew and Alternaria solani blight, which causes reddish-brown lesions on the leaf. Fungicides can be used to overcome any problems but on the whole zinnias are trouble-free as long as summers are hot.

Staking may be necessary for taller zinnias. A single bamboo cane behind each plant, with string looped around the principal stems, is sufficient. Plants should be deadheaded regularly unless spent blooms are hidden by new flowers.

What to plant with zinnias

Zinnias make good partners to a range of summer flowering plants, including salvias. Zinnia ‘Benary’s Giant Salmon Rose’ is a stunning cohort to the fine velvet red lances of Salvia confertiflora with a backdrop of green and cream variegated Euonymus fortunei ‘Silver Queen’. Zinnia ‘Benary’s Giant Lilac’ is equally effective next to intense blue Salvia ‘Indigo Spires’, flowering until autumn.

The tall fleabane (Erigeron annuus) produces a froth of white daisies all summer long, setting off the rich red heads of Zinnia ‘Benary’s Giant Red’. Zinnia ‘Dreamland Scarlet’ and Zinnia ‘Profusion White’ or Zinnia ‘Profusion Orange’ blend well with the pale blue South American annual Browallia americana.

26 of the best flowering shrubs https://www.gardensillustrated.com/plants/shrubs/best-flowering-shrubs/ Mon, 13 Mar 2023 15:49:35 +0000 https://www.gardensillustrated.com/?p=102625

Shrubs are often described as the backbone of a garden, and can offer not only beautiful flowers but height and structure, foliage and berries.

Flowering shrubs are often excellent for attracting bees, butterflies and other pollinators, and many have the added bonus of deliciously scented flowers. They can also provide much needed shelter, food and habitat for wildlife – birds are more likely to visit bird feeders if they have protective shrubs to dart in and out of.

Read about the best shrubs for birds.

Some flowering shrubs have evergreen foliage and look good all year round; others are deciduous, and may offer beautiful foliage in autumn before it falls. Deciduous shrubs can be underplanted with spring bulbs such as crocus or spring flowers such as primulas, which flower before shrubs come into leaf.

You can grow flowering shrubs as focal points in a front garden or lawn or grow them in a mixed border of shrubs, perennials and annuals.

There are flowering shrubs to suit every garden. Choose carefully and you can enjoy shrubs in flower in every season of the year.

Are there any shrubs that flower all year?

There are no shrubs that flower continuously all year round. However, some shrubs do flower for a very long time, straddling two seasons, such as abelia, which starts flowering in summer and continues well into autumn. With a little planning you can plant flowering shrubs to add interest in your garden for 12 months of the year.

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.

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’

Another from the Stripe group, this is an unusual form with lightly dusted, purple and lemon stripes. An often variable but handsome plant. 15-20cm. RHS H5, USDA 3b-9b.

 

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.

Fast growing flowers: quick perennials to grow from seed https://www.gardensillustrated.com/plants/flowers/fast-flowers-quick-perennials-from-seed/ Tue, 07 Mar 2023 13:50:39 +0000 https://www.gardensillustrated.com/?p=102544

With perennials often costing £10 and upwards at the garden centre, it makes sense to grow your own from seed. Sown in early spring, many perennials will flower in their first year, and will come back every year, making them excellent value.

We asked four experts – Derry Watkins, owner of Special Plants in Wiltshire, Xa Tollemache, garden designer, Joseph Atkin, head gardener at Aberglasney Gardens in Camarthenshire and Marina Christopher, nurserywoman and skilled propagator, to recommend their favourite fast perennials to grow from seed.

How to grow perennials from seed

  • Most hardy perennials can be sown in early spring, under cover in modules or seed trays at a constant temperature of around 18-20°C – a heated propagator helps to ensure a steady temperature.
  • Once the seedlings have germinated (this can take anything from a couple of weeks to a couple of months, depending on the plant), remove them from the propagator and place on a sunny windowsill or in a greenhouse.
  • Once they have produced true leaves, prick them out.
  • As they grow, pot the seedlings on into larger pots.
  • Harden off before planting out in late spring or early summer.
  • Alternatively, you could scatter the seed where you want it to grow in late summer or autumn, when most plants are naturally producing seed.

For more advice on sowing seeds, head to our detailed guide to planting seeds.

Spectacular, big, near-black flowers speckled with tiny white stamens. A tall plant, usually grown as a cut flower, this will need some support and a few friends around it to hide its rather unattractive legs. Height: 90cm. RHS H4.
Recommended by Derry Watkins

Pennisetum thunbergii ‘Red Buttons’

Grow this for its pale-pink, wide-open, mallow-like flowers, which are arranged in spires on upright stems, and will bloom on until the first frosts if deadheaded. Very showy and loved by bees. Height: 90cm
Recommended by Derry Watkins

Antirrhinum majus ‘Sonnet White’

One of the selections from the Sonnet Series, ‘Sonnet White’ offers upright stems crammed with those familiar-looking snapdragon flowers in pure white. Often grown as an annual, the Sonnet Series can also be grown as a short-lived perennial. It’s a great cut flower and loved by bees, as well as being easy to grow from seed. Sow February to April. Height: 45cm. RHS H3, USDA 7a-10b.
Recommended by Xa Tollemache

Cephalaria gigantea

I love this at the back of a border, floating about and attracting bees – and such an exciting plant to have grown from seed. Scabious-like flowers in cream with a tinge of yellow are held high on long stems. Another great choice for pollinators and as a cut flower. Sow in March for summer flowers. Height: 1.8m. RHS H7, USDA 3a-7b.
Recommended by Xa Tollemache

Delphinium Belladonna Group

There are various cultivars in this group, offering choices in pink, white, blue and purple. It’s the brilliant blues that I really love. Tall stems with racemes of delicate- looking flowers make great impact in border and are perfect for cutting. Sow indoors in spring. Height: 1m. RHS H4, USDA 4a-8a.
Recommended by Xa Tollemache

Achillea ptarmica ‘The Pearl’

This is a charming little border plant, growing quickly to form a mound. It can be invasive but don’t let that deter you from growing what is sometimes described as
a perennial gypsophilia, with its sprays of white double or semi-double button flowers. Cut back after flowering for a second flush. Sow indoors February to June. Height: 75cm. RHS H7, USDA 3a-9b.
Recommended by Xa Tollemache

Oenothera lindheimeri

Gaura lindheimeri, now Oenethera lindheimeri

My favourite of all time – and in flower June to November. Previously known as Gaura lindheimeri, its tall stems with willow-like leaves hold aloft the white-flushed-pink, star-shaped flowers with their delicately dangling anthers. Good drought tolerance and loved by pollinators. Sow indoors January to May. Height: 1.2m. AGM*. RHS H4, USDA 5a-9b.
Recommended by Xa Tollemache

Papaver orientale

Over the past 20 years, agastache have developed into great garden plants, and ‘Apricot Sprite’ would be my first choice, mainly for its wonderful orange colour,
which works well with strong pinks, blues and purples. Given a free-draining soil and a sunny position, they are reliable perennials and fit brilliantly with the informal naturalistic style. Height: 45cm. RHS H2, USDA 6a-9b.
Recommended by Joseph Atkin

Verbena hastata

This verbena gets less attention than its relatives, but it’s a wonderful plant for small spaces as it’s over 1m tall but takes up very little room. It also self-seeds nicely, and distributes itself sensitively through herbaceous borders. We would not be without it. Height: 1.2m. RHS H5, USDA 3a-8b.
Recommended by Joseph Atkin

Digitalis purpurea Camelot Series

Foxgloves are a garden stalwart, and we use a number at Aberglasney, but the Camelot Series, in pink, white and cream, are the most reliable first-year flowering and longest lasting for us. If started early under glass, they will flower in their first year in a home-garden situation. Height: 1m. RHS H5.

This colourful daisy can be short-lived, but happily seeds around on light, well-drained soils. This strain is similar to the species, with multi-branching stems and multitudes of small flowers, which open golden-yellow and develop an intense reddish-orange halo around a dark-brown cone as the season progresses. Height: 1.2m. RHS H6, USDA 4a-8b.

30 of the best climbing plants for 2023 https://www.gardensillustrated.com/plants/30-of-the-best-climbing-plants/ Fri, 03 Mar 2023 15:00:37 +0000 https://www.gardensillustrated.com/?p=20

Here we’ve rounded up a selection of the best climbing plants, perfect for your garden. We’ve divided the list into climbers for walls, borders and vigorous examples.

Climbing plants, including favourites such as honeysuckle and jasmine, all share the successful strategy of relying on the support of other plants or objects to reach the sunlight. This obviates the need to invest much in producing supportive tissue, such as the wood in trees, and means climbing plants aren’t subject to the usual restraints on growth.

Here are the best climbing plants

How to choose a climbing plant

A climbing plant can be a wonderful addition to your garden planting, and there are plenty more out there to choose from than just the regular honeysuckle or clematis or passion flower. The way to choose your climbing plant depends a lot on the space you have and what you want your plant to be used for. Here are some tips on how to choose the best climbing plant:

  • What do you want it to grow up? If you’re using your climbing plant as a screen, then you will want a vigorous climber that provides good, evergreen coverage, with hopefully flowering bonuses at some point too. If it’s something you’ll be looking out onto, make sure you pick a climber you love. They tend to dominate wherever they are.
  • Do you have the right supports? A climber needs the right support, so make sure you invest in the correct plant support, or your wall, trellis or even tree is suitable for the particular climber.
  • Do you have time to look after it? Lots of climbers are fussy and lots of climbers need work to prune it at the right point in the year. If you’re looking for something that you can chop once a year and then leave to do it’s own thing, consider a Clematis ‘francis rivis’ or Hedera algeriensis ‘Gloire de Marengo’.

Luxuriant growth brings its own problems – vigour must be matched carefully to the appropriate space, and abundance restrained where necessary. If you need some climbing supports, we have rounded up our favourites,  and don’t miss our guide to pruning climbing plants like wisteria.

Clematis montana: how to grow and prune, plus the best varieties https://www.gardensillustrated.com/plants/best-clematis-montana/ Mon, 27 Feb 2023 11:45:08 +0000 https://www.gardensillustrated.com/?p=2607

The National Collection of Clematis montana is held Val Le Neville-Parry at her garden By The Way in Salisbury, Wiltshire, and contains more than 200 plants in 50 named varieties and cultivars.

Some Clematis montana are rampant, reaching 8m or more, but clematis breeding has produced more compact varieties that are suitable for growing in smaller gardens, or even pots. For all types, flowering is longer than is often assumed, starting in early March and continuing into late June. All Clematis montana go on to produce fluffy seedheads in autumn and into winter.

Foliage is also a feature. “I love the leaves as much as the flowers,” says Val, who shares her recommendations here. Many are available commercially, although some can currently only be seen growing at By The Way.

Clematis montana 'Marilyn'

How to grow Clematis montana

Medium and large Clematis montana 

The more vigorous types of Clematis montana can reach 8m or more, with some of the fully vigorous cultivars reaching 10-12m, depending on growing conditions. These are versatile plants with many uses in the garden.

In her garden, Val uses a Clematis montana var. grandiflora to transform a laurel hedge running down one side of the garden; its shining white blooms, which are among of the largest flowers in the group, sit like butterflies on the glossy leaves of the laurel. Both clematis and laurel are pruned together and thrive on it. The vigorous Clematis montana var. wilsonii can be used as ground cover where space permits. It forms an undulating carpet of foliage studded with scented creamy-white flowers in early summer.

Compact Clematis montana

Many varieties and cultivars of Clematis montana have been bred to have a more contained habit that is less rampant than the vigorous ones. These compact montanas grow to around 4-7m, depending on cultivar and growing conditions, and are a great choice to grow over arches and obelisks. They can be grown on the trunks of mature trees or up poles to add vertical interest to a bed or border.

Compact Clematis Montana will also grow successfully in large pots (at least 50 litres) with a loam-based growing medium with regular watering and feeding with a slow-release fertiliser. Regular watering and annual feeding with a slow-release fertiliser are both essential.

Compact clematis cultivars can be combined with later flowering Clematis viticella or encouraged to scramble up plant supports, obelisks or poles to add vertical interest to a border.

Pruning Clematis montana

Clematis montana is in Clematis Pruning Group 1. It does not need regular pruning, but if is getting too large or leggy, cut it back after flowering, in spring. Regular pruning will encourage strong growth and good flowering and will ensure that the flowers remain at eye level, with no bare, tangled stems at the base.

Plant profile: late flowering clematis https://www.gardensillustrated.com/plants/plant-profile-late-flowering-clematis/ Mon, 27 Feb 2023 10:30:28 +0000 https://www.gardensillustrated.com/?p=2762

Most of us know clematis as climbing plants with large showy flowers. But in fact, among the 320-odd species, these are a minority. Late-flowering species clematis are usually, but not always, climbing, sometimes sprawling over rocks, or forming bushes in deserts, or growing alongside grasses in meadows. Some are very vigorous, clambering over trees or rocks to reach the light, their roots usually deep in the cooler and moister levels of the soil. Others are relatively small and can be grown in containers, which makes them useful for town gardens.

Very few, however, are showy, and you need to give careful thought to placing them – you’ll want to get up close to be able to appreciate their subtle colours, and intriguing shapes and textures of their flowers – not to mention the scents some have. Many of these species flower relatively late – from midsummer, off and on, into early autumn – which is perhaps one reason they are getting increasing attention from nurseries and gardeners.

The best known of the later-flowering clematis are the ‘lemon-peel’ species: Clematis orientalis and Clematis tangutica. Both are an excellent introduction to the very large number of late-flowering species, and illustrate well one of the additional advantages of these later- flowered kinds – their spherical fluffy seedheads, produced profusely from September onwards. A big Clematis orientalis, with several thousand silvery heads, illuminated by low winter sun, can be a spectacular sight.

There are many more late-flowering clematis to discover. I would specifically like to mention the up-and-coming Clematis viorna group, a few of which are pictured here and are something of a cult in the USA, with more becoming available in the UK. With their intriguing flask-shaped blooms and wide, often subtle, colour range, these clematis (known as ‘leather flowers’) offer an enticing prospect, especially for small spaces.

With their tiny flower heads and sometimes unusual colours, these late-flowering clematis have lots of appeal, and show that when it comes to climbing flowers, bigger isn’t necessarily more beautiful.

Clematis x aromatica. A hybrid between C. flammula and C. integrifolia. Panicles of small, violet-blue flowers with white stamens, the petal edges rolling under as the flower matures. An excellent choice for those who are looking for scent. Flowers from July to September. 2m. RHS H6.

How to grow late flowering clematis

Site and soil

Having seen several species in the wild growing in the most appalling ground, I am not inclined to worry about soil conditions, except to stress that late flowering clematis do all need good drainage. All will need sunlight for at least half the day. The majority will cope with high summer temperatures but go into dormancy if their roots run dry. Hardiness is not a problem for the species in cultivation. The yellow ‘lemon-peel’ varieties establish quickly, but some others may be slower.

Pruning late flowering clematis

Nearly all late flowering clematis flower on the current season’s growth and are in Clematis pruning group 3. They can be pruned in late winter or early spring. Pruning can be as hard as it needs to be, which allows potentially large-growing plants to be kept to much smaller sizes, or at the other extreme, in a wilder planting, they need not be pruned at all and can be allowed to run rampant.

But be warned: clematis growth is often wayward and always very brittle, so you may find when you set out to tidy up an older plant that what starts as a light prune can often turn into something more serious, leaving a growing pile of tangled debris at the bottom of the ladder.

Plants on house walls are best cut back annually to a framework of permanent stout stems. Clematis will need both horizontal and vertical support to climb a wall or fence. Wooden trellises are readily available, but you can create your own by attaching wires to walls using vine eyes. Whatever you use, each element should be no more than 20cm apart, and preferably closer lower down.

Read our guide to pruning clematis.

What to grow with late flowering clematis

One of the great boons of climbers is that it is often possible to grow several together, allowing for an easy succession of flower throughout the year. The clematis mentioned here, for example, can be allowed to scramble up alongside wisteria, early flowering Clematis montana or roses, to provide colour later in the year. The main issue is that different climbers may have varying pruning requirements, so, for example, giving younger wisteria plants the ruthless cut-back they need in summer may result in a lot of damage to the clematis. The best strategy is perhaps to plant clematis only around old and well-established wisteria and roses.

As clematis age on high walls, more of their flowers will be higher up (one reason to prune), although this provides an opportunity to plant other shorter-growing plants below, such as the early flowering C. alpina and C. macropetala, or other small-growing species, such as C. viorna types.

15 of the best late-flowering clematis to grow

1

Clematis tangutica

© Rachel Warne

Named for the Tangut region of Tibet, this plant is found over a wide area, in many different kinds of terrain. Its yellow, lantern-shaped flowers are followed by charming, fluffy seed heads. Height: 4.5m. RHS H7, USDA 3a-8b.

2

Clematis texensis

This species forms the basis for many new and showy hybrids, mostly noted for their vivid flowers, often in red with creamy inners. Texensis clematis are herbaceous, so need cutting back. Height: 1.8m. USDA 4a-8b.

 

3

Clematis fusca

Dark leaves and flowers, which look almost as though they’re made of felt, give this plant a subtle, somewhat sombre charm. A good clematis to let ramble through a shrub. Best in a sheltered spot with good drainage. Height: 2m.

 

4

Clematis versicolor

This lovely North American native, one of the C. viorna group, can flower from late spring right through to late summer, early autumn. Its light habit means it is good for growing over shrubs. Height: 2.5m. USDA 5b-9a.

 

5

Clematis ‘Sonnette’

A pretty British cultivar that is derived from the uber-cool North American C.viorna. It is extremely free-flowering but luckily doesn’t grow too large. It does, however, need hard pruning. Height: 90cm-2m. RHS H7, USDA 5a-10a.

 

6

Clematis ‘Buckland Beauty’

Rachel Warne

Bearing little mauve flowers that are pale yellow on the inside, this viorna clematis is small enough to grow in a container. Flowers over several months in summer. Prefers a warm spot; herbaceous, so best pruned back to base annually. Height: 1.8-3m. RHS H7, USDA 4a-9b.

 

7

Clematis Princess Kate (=’Zoprika’)

Normally, this clematis group has bell-shaped flowers, but this has white flowers with red-pink backs that flare open to about 5cm wide. Dies back to ground level in winter.
Height: 3.5m. RHS H7. USDA 6a-9b.

 

8

Clematis ‘Fukuzono’

A small, non-clinging plant with lovely fresh foliage. Its open blue-purple flowers are larger than many late bloomers, and are produced over a long season. Its name is Japanese for ‘happiness-garden’. Height: 1.5m.

 

9

Clematis Twinkle (=’Zotwi’)


This is one of the ‘integrifolia’ group of clematis, which means that it does not climb, but behaves more like a perennial, without any need for support. It is sweetly scented. Height: 1m. RHS H7.

 

10

Clematis tubulosa ‘Wyevale’


Another non-climbing species with no need for support. Its exquisitely scented flowers are produced in midsummer, with a few later on. Looks good with the first Japanese anemones or Tricyrtis. Height: 1m. RHS H7, USDA 5a-9b.

 

11

Clematis rehderiana


Tiny, sweetly scented flowers are produced in large quantities in mid to late summer. Vigorous, it will eventually reach quite a height, but can be kept small with an annual hard prune. Height: 7m. RHS H6, USDA 6a-9b.

 

12

Clematis ‘Pamela’


Bred in Canada, this is another non-climbing, sprawling cultivar. It is best grown through large perennials or into a shrub. Masses of scented flowers are produced throughout the summer. Height: 2m. RHS H7.

 

13

Clematis ‘Sweet Scentsation’


Producing a profusion of small, scented flowers throughout the summer, this plant grows to a medium height. It’s a new cultivar, of rather mysterious origin, that needs a hard annual prune. Height: 2.5m. RHS H7.

 

14

Clematis ‘Kaiu’


This cultivar, bred from C. viticella, was raised in the cool climes of Kaiu in Estonia, so is pretty hardy. Its small, nodding flowers open to a very pale purple but fade to a creamy white. Needs hard pruning. Height: 2m. RHS H7.

 

15

Clematis ‘Paul Farges’


Wide-open, scented flowers, 5cm across, on a plant that can climb to a great height, so very useful for long fence runs or sending into trees. Height: 4-8m. RHS H7, USDA 3a-9b.

Best early-flowering clematis: expert’s choice https://www.gardensillustrated.com/plants/best-winter-flowering-clematis/ Mon, 27 Feb 2023 09:00:25 +0000 https://www.gardensillustrated.com/?p=300

Plants that flower during the winter should be treasured far more than those that are part of the chorus of high summer. At the start of winter, one of the moments I look forward to is seeing the first few tentative flowers on the Clematis cirrhosa that covers the woodshed. I know that by January the plant will be a clematis blanket of creamy-yellow bells.

Clematis cirrhosa is one of several winter-flowering, evergreen and semi-evergreen clematis that, although they have no formal botanical grouping, all flower during the winter and early spring. With many to choose from, we should never be short of the sparkle and joy of winter flowers.

Here are the best winter-flowering clematis

 

Don’t miss our focus on Clematis montana, which late-flowering clematis to choose and how to grow herbaceous clematis.

Pruning early clematis

Early flowering clematis flower on growth made the previous year, so wait until they have finished flowering before doing any pruning. They do not need routine pruning but you can tidy them up if necessary.

After three or four years, Clematis armandii and Clematis cirrhosa may develop woody, bird’s nest growth. Cut back about one third of the plant to the base and the repeat the process on the other two thirds in subsequent years.

Clematis ‘Early Sensation’ and the cartmanii hybrids produce so many flowers that they often exhaust themselves and generae little in the way of new growth. To keep the plants vigorous and healthy, prune them in two stages:

  • Trim them immediately after flowering, to remove the dying flower heads and prevent any energy being lost in seed production.
  • At the end of May, cut the whole back to about 50cm from the ground, to encourage new growth and prevent the plant becoming bare and woody at the base.

How to grow winter flowering clematis

Hardiness

Clematis x cartmanii and associated hybrids were originally thought too tender to grow outdoors in Britain. In fact winter-flowering clematis will thrive in sheltered places that do not drop below -5°C during the winter, as long as they are protected from cold, drying winds. In colder areas, grow in pots in cool greenhouses or conservatories.

Cold winds are also the enemy of Clematis armandii so choose a sheltered spot in sun or part-shade.

Where to plant winter flowering clematis

In general, winter-flowering clematis prefer moist conditions but Clematis cirrhosa must be kept dry, especially during the winter. An ideal place to plant it is on a south or west-facing house wall, where the eaves of the roof protect the soil from heavy downpours.

Clematis need rich, moist soil with a cool root-run, so plant close to the base of perennials or shrubs to shade the soil. Clematis armandii needs to be well fed, so apply a generous mulch of compost every autumn.

Plant supports

Clematis cirrhosa will need a plant support at first – tie the stems in to 1m canes. As it becomes established it will twine itself around wires, posts or trellis. Clematis x cartmanii hybrids are not twining plants so they are unable to support themselves when grown as climbers. They can be left to sprawl along the ground or to flow over the edge of pots.

How and when to prune winter-flowering clematis

How to prune Clematis armandii and Clematis cirrhosa

Clematis armandii and Clematis cirrhosa are vigorous plants that need regular pruning to be kept under control.

  • They flower on growth made the previous year, so wait until they have finished flowering before doing any pruning.
  • Cut back growth to about 1m below the area you want the plant to cover.
  • After three or four years both Clematis armandii and Clematis cirrhosa may develop dense, woody ‘bird’s nest’ growth. Cut back about one third of the plant to the base and repeat the process on the other two thirds in subsequent years.

 

How to prune Clematis ‘Early Sensation’ and Clematis x cartmanii

Clematis ‘Early Sensation’ and the cartmanii hybrids produce so many flowers that they often exhaust themselves and generate little in the way of new growth. To keep the plants vigorous and healthy, prune them in two stages:

  • Trim clematis immediately after the flowers have finished, to remove the dying flower heads and prevent any energy being lost in seed production.
  • At the end of May, cut the whole plant back to about 50cm from the soil, to encourage new growth and prevent the plant from becoming bare and woody at the base.

How to prune Clematis paniculata

Clematis paniculata tends to be spindly, but looks better with bushy growth.

  • For a few years after planting, cut back to 60cm from the ground.
  • Once it has become bushy, allow it to grow into the size you want and then trim it back each year after flowering.

The best spring flowers to plant

Anemone nemorosa ‘Kentish Pink’

© Maayke De Ridder

I’m always amazed that Anemone nemorosa doesn’t generate the same levels of excitement as snowdrops in springtime. These wood anemone offer far more variation – the Austrian breeder Christian Kress has a collection of 140 types – and naturalise well. This cultivar is almost white but the backs of the petal-like sepals are pink, so in full sun it looks like a typical, white wood anemone, but when light is low, and the spring flowers start to close, its appearance changes completely. In some lights the flowers can appear dark pink. Height 20cm. Origin Western Europe. Conditions Well-drained, humus-rich soil; part shade.  Hardiness RHS H6, USDA 5a-8b. Season Spring.

 

Paeonia lactiflora ‘Hot Chocolate’

This early season spring is peony is an unusual colour combination with dark-red spring flowers and a pompom-like boss of frilly petaloids.

Here’s our guide to peonies

Erysimum ‘Bowles’s Mauve’

© Sharon Pearson

This classic long-flowering mauve erysimum forms a tall, upright plant that stays erect. Longer-lived than many. A spring flower that deserves a place in every garden, but sadly not scented. Can set a little seed on rare occasions.

Here’s everything you need to know about erysimum

Fritillaria raddeana

© Maayke De Ridder

Fritillaries feel like an unstoppable  force of nature. You turn away for a couple of days and then suddenly  there are numerous new stems with shiny green foliage. This fritillary’s spring flowers have a beautifully subtle,  lime-green colour, which fits perfectly into spring’s colour palette. They’re also large, making this a very striking plant. It is one of the first fritillaries to flower and prefers well-drained soil  and hot dry summers. After flowering, it evolves into large, angular seedpods that look wonderful when used in  flower arrangements. Height 70cm. Origin Central Asia. Conditions Well-drained, humus-rich soil; full sun or part shade. Hardiness RHS H7, USDA 5a-8b. Season Spring.

Corydalis nobilis

© Maayke De Ridder

In his book Garden Myths, Robert Pavlis describes how the botanist Carl Linnaeus received some incorrectly labelled seeds that he planted out in his garden. They turned out to be Corydalis nobilis, and from his garden in Sweden the plant has now naturalised all over much of northern Europe. I find this a beautiful story for a beautiful plant. It’s one of the largest corydalis with striking yellow-brown flowers. Most plants need some heat to see a real spurt of growth, but this plant benefits from cold to form up  a solid plant. If spring is too warm it slows and collapses. Height 50cm. Origin Altai Mountains and central Asia. Conditions Dry to moderately moist  soil; full sun. Hardiness RHS H7, USDA 3b-8b. Season Spring.

Here’s how to grow corydalis

Paeonia lactiflora ‘Bowl of Cream’

© Jason Ingram

Every petal on this peony is smooth, scented, creamy-white. It double flowers, curves inwards and forms a bowl-like centre. Spring flowers from early mid season to late season. 80cm. RHS H6.

Helleborus atrorubens 

© Jason Ingram

Deciduous leaves have up to 15 divisions. The small, flowers are mainly green inside with reddish-purple backs. Still confused with the Helleborus orientalis cultivar once known as ‘Atrorubens’, now called Early Purple Group. Spring flowers from February to March. 25-35cm. RHS H5, USDA 6a-8b.

Whether you’re thinking of beginning as a flower farmer professionally, want a few cut flowers for your own use, or would like to have a go at making a boutonniere or buttonhole flowers, having a selection of blooms that will look perfect in a cut flower arrangement can be a satisfying way of lifting the mood and bringing the outside in to your house.

The below selection all come from James Rowe’s flower farm, which grows cut flowers in the grounds of a medieval priory in North Yorkshire. With approximately two acres, the farm has excellent loam which has been well-worked over decades. The climate can be affected by a cold sea-fret as the farm is only five miles from the North Sea, but below’s selection are a few that work very well in the farm. James is the third generation of growers at the priory, his father Eddy sows seeds directly into the ground in mid-April in long rows for ease of picking.

Everyone’s plot is different, so you need to pick the right cut flowers for you. But below is a good starting point, with a selection of cut flowers that will have your friends and family asking who your florist is.
