Cyclamen: How to care for cyclamen and growing tips
Cyclamen are a welcome sight in the colder months when little else is in flower. Plant expert John Hoyland recommends his 12 favourite cyclamen and gives advice on how to care for them. Photographs by Jason Ingram.
Cyclamen are a genus of about 20 tuberous perennials grown for their pink and white flowers. Most grow to about 10cm tall, although established tubers can reach the size of a dinner plate and produce dozens of flowers.
Most cyclamen are found growing around the Mediterranean and across southern France, Italy, Greece and into Turkey. Cyclamen habitat ranges from deciduous woodland to scrubland and rocky areas.
Here's our top tips for cyclamen care
When do cyclamen flower?
Some cyclamen species flower from September to December, others from December to March.
Cyclamen hederifolium or the ivy-leafed cyclamen slowly naturalises to form sheets of flowers in autumn, and the marbled leaves are attractive in winter.
Cyclamen coum flowers in the depths of winter, with round leaves and small flowers in white, pink or magenta. It looks lovely growing with snowdrops.
Cyclamen cilicium is a lesser known, autumn-flowering cyclamen. It is hardy and will naturalise in light shade. The glossy foliage is a good winter feature.
Cyclamen persicum is often seen for sale in shops, florists and even petrol stations. The wild form is a beautiful spring-flowering plant but it is generally grown as a house plant or a late-season bedding plant as it is not hardy and needs protection from frost. It should flower for around six weeks in winter and spring in a cool, bright room.
Where to grow cyclamen
In general, hardy cyclamen prefer poor, well-drained soil in full or part shade. Hardy cyclamen are easy to grow as long as you avoid heavy soils that are apt to get waterlogged. If you do have very wet soil it is probably best to grow cyclamen in pots or raised beds. Cyclamen are at their happiest around the base of deciduous trees and large shrubs. These are areas that are cool and shady in the summer but light and moist during the autumn and winter. They look especially good growing around shrubs with colourful stems.
Cyclamen can also be grown in pots. Plant in a soil-based compost and leave them undisturbed. If you want them to form part of a pot display, keep them in their own pots and sink them into the compost.
When to plant cyclamen
An important consideration when growing and caring for cyclamen is whether to buy them as dry tubers or as already rooted plants in pots.
Potted plants are more expensive but will establish more quickly and flower immediately; tubers will take some time to establish and probably won’t flower the first year after planting. Plant container-grown cyclamen at the same level as they are in their pot.
The best time to plant cyclamen tubers is in autumn. Make sure that they are the correct way up – the flat or slightly indented face is the top. Plant them around 4cm deep.
How to propagate cyclamen
It is only possible to propagate cyclamen from seed. The sweeps of cyclamen that are seen in the wild are a testament to the nifty ways in which the genus has developed to ensure that its seed is distributed efficiently. Cyclamen seeds are held in capsules on the end of spring-like stems that unwind to deposit the seed as close to the ground as possible, increasing the chances of germination. Seed distribution is further assisted by ants, birds and small mammals. Attracted by the sweet coating covering the seeds, ants take away the seeds to a safe place, eat the sugars and leave the seed to germinate. Small birds that are attracted to the sweet treats eat them and then redistribute the seeds through their droppings.
The oft-quoted advice of collecting cyclamen seed and sprinkling it around has never worked for me. The expanse of cyclamen in my own garden have been produced by simply letting nature do the work and (very occasionally) collecting and sowing the seed of a species I wanted to encourage.
Cyclamen seed should be sown as soon as possible after it ripens in seed trays or shallow pans. I use John Innes seed compost with a small amount (about 10 per cent) of perlite and the same amount of leaf mould. The seed should be sown thinly and covered with about one centimetre of horticultural grit. Leave the containers in a shady place outside, keep the compost moist and wait. Germination is irregular, with some seedlings appearing after a couple of months and some waiting a year or so. Leave the young plants in the trays for a second year to develop a tuber and then plant out in the garden when they are dormant, roughly between May and August.
The only serious pest of cyclamen is vine weevil, especially in pots. A biological control is available but only works well in the warm summer months.
The best cyclamen to grow
