African Lily Twister A compact, bi-coloured form of agapanthus or African lily, Agapanthus Twister is a clump-forming, deciduous perennial, ideal for the smaller garden. Strap-like, deep green leaves appear in spring. From July to September, large, globular flower-heads of trumpet-shaped, white florets with a violet-blue base are borne on sturdy stems. African lilies are very good in pots, grown in soil-based compost with slow-release fertiliser granules, as they flower well when their roots are confined, but be aware that pot-grown plants are more vulnerable to frost, so the pots should be brought under cover in winter in colder areas. African lily Twister holds the RHS Award of Garden Merit.
