Broad-petaled white blossoms with gleaming black centers appear in clusters of 15 or more atop sturdy foot-high stems.
Pot the tender bulbs in fall, keep cool and dark to promote root growth. When top growth appears, move to light and water well to induce spring flowering. After blooming, keep foliage growing until it ripens, dry off and store bulbs in pots until fall. Repot in fresh soil before new growth cycle begins.
Other popular species for pot culture are O. umbellatum (Star-of-Bethlehem), green-margined white flowers; and O. thyrsoides aureum, golden-yellow flowers.
