The gorgeously coloured, shallow bowl-shaped De Caen anemones, Anemone coronaria ‘De Caen Group’, are well-known as cut-flowers, sometimes called florist anemones, and are available almost all year round. Gardeners can achieve a similar long season of colour by planting the claw-shaped corms at various seasons – in April for June and July, in June for September, and in September or October in mild areas or under cloches for late winter and early spring blooms. After flowering, the corms can be lifted and dried, or they may be left in the soil permanently, when they will flower annually in spring.
For best results grow Anemone coronaria ‘De Caen Group’ in moist but well-drained soil, in partial shade. If growing as perennial spring flower, mulch the tubers annually with well-rotted manure or compost.
