Crinum powellii


It is a genus that brings together some dozens of species of bulbous plants, originating in Asia, Central and South America, and Africa; the species of tropical origin are evergreen, the others lose the aerial part during the cold season. These are fairly large bulbs; produce large tufts of ribbon-like leaves, 30-50 cm long, arched, fairly cuoiose and thick, dark green; in late spring and in summer from the center of the leaves develops a long cylindrical stem, 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 the belladonna amaryllis, with which they can hybridize.


The plants of this genus are placed in a sunny place, or partially shaded; some varieties can withstand fairly harsh winter temperatures, but in general it is necessary to place these bulbous plants in places with fairly mild winters, where temperatures do not reach very low values. Given that i crinum powellii do not like to be moved, it is advisable to cultivate the little rustic species in pots, so as to be able to take the containers to a sheltered place in late autumn. It is better 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.


From March to October water regularly; these bulbous plants love moist soils and can also be grown near water gardens. They can't stand drought. During the winter season, on the other hand, the watering can be reduced consistently, intervening only during the hottest days and in the case of particularly dry periods, always taking care to check the possible formation of water stagnation that can cause the onset of fungal diseases.


These plants are grown in a good soil rich in organic material, soft, well-drained, and always slightly moist. Bulbs grown in pots require large containers, with a diameter of at least 10 cm wider than the diameter of the bulb; they are repotted every 3-4 years, to avoid excessively disturbing these bulbous plants, which often do not bloom immediately after being repotted. They are buried a little deep, leaving the upper part of the bulb outside the ground.


Every 4-5 years the tuft of leaves is unearthed, from which the smaller bulbs stand out, to be planted and which will bloom within 2-3 years. The crinum powellii also propagate by seed, the young plants take 4-5 years before being vigorous enough to produce flowers; in this case, the new plants may be slightly different from the plant that supplied the seeds.

Crinum powellii: Pests and diseases

Generally the specimens of this genus are not attacked by pests or diseases. Although they are plants that require a certain degree of humidity, however, in the presence of an excessive rate it is possible that fungal diseases, even very harmful, may occur.
