Pineapplebelong to the Hyacinthanceae family and are native to South Africa. The 30 cm (12 in) long leaves are oblong with a wavy margin. The greenish-yellow flowers with purple edges are borne on tall spikes of about 60 cm (24 in), crowned by a cluster of green, leaf-like bracts. The pineapple flower needs a sunny, warm position. As soon as the leaves begin to develop, increase the watering and apply small, weekly closes of fertilizer.
Reduce the watering outside the growing-season. In winter, store the container or just the bulbs in a dark place at a temperature of 5-10° C (41-50° F). Propagate by dividing the clumps in spring. Raising from seed requires more patience. Snails and slugs may be a problem.
