It is a genus that brings together some tens of bulbous species, originating in Asia, central-southern America, Africa; the tropical species are evergreen, the others lose the aerial part during the cold season. These are bulbs of fairly large size; they produce large tufts of ribbon-like leaves, 30-50 cm long, arched, fairly leathery and thick, dark green in color; in late spring and summer from the center of the leaves a long cylindrical stem develops, erect, slightly fleshy, up to 70-90 cm high, which bears some large flowers, similar to lilies, of white, pink or red color. THE crinum powellii are very similar to amaryllis belladonna, with which they can hybridize.
Plants of this genus are planted in a sunny or partially shaded place; some varieties can withstand fairly harsh winter temperatures, but generally it is necessary to plant these bulbous plants in places with rather mild winters, where temperatures do not reach very low values. Since i crinum powellii do not like to be moved, it is advisable to grow the little rustic species in pots, so as to be able to bring the containers in a sheltered place in late autumn. It is best that these plants receive a few hours of light a day, but not when the temperatures are quite high and when the sun's rays are warmer.
