The African Lily comes from South Africa and occupies open grasslands and rocky places ,we should therefore consider a similar situation in the garden: full sun, mineral rich soil more on the heavy side and not too wet. The ones that loose their foliage are generally far more hardy. Ours are all grow outdoors in pots and remain unprotected through the Winter.
Large heads of white trumpet flowers in summer above strappy green foliage. Tough and easy plants for hot and sunny locations and pots.
