Any gardener wanting to introduce a subtropical feel to a sunny part of the garden should consider planting Crinum x powellii, the hardiest member of the crinum genus. It is not the easiest bulb to grow, demanding mild conditions, and frequent tidying up if it is to look at all presentable. But perseverance is rewarded with an exotic display of white or pink lily-like.
Grow crinums in clumps in a sunny position protected from north and east winds — perhaps the base of a south-facing wall. They also flourish in containers on sunnyin summer. Plant in late spring in rich, moisture retentive, but well-drained soil. Set them 30-45cm (1 – 1-1/2ft) apart with their necks just below soil level. Water freely during the summer, then ease off in autumn. Keep those in containers almost dry during the winter. Protect young shoots from frost with a light mulch of bracken, coarse sand or straw. Move container-grown crinums into a frost-free greenhouse during winter.
Crinums prefer not to be disturbed. You can propagate them by removing offsets in early spring and replanting. However, these will take three years to develop into flowering plants.
