Hippobroma longiflora

Hippobroma longiflora, a native of the West Indies, is a perennial herb with poisonous milky sap. They will reach 2 feet in containers and are very showy when in bloom.

Blooming Time: Summer-Fall. The white flowers are 3½ inches long and 2 inches across.

Culture: Hippobroma longiflora will grow in part shade to full shade with a rich, well-drained soil. In the greenhouse, we use a soil mix consisting of 2 parts peat moss to 1 part loam to 2 parts sand or perlite. During the growing season, the plant should be kept moist for optimum growth. Fertilize weekly with a balanced fertilizer diluted to ½ the strength recommended on the label. During the winter months, water less and do not fertilize. I recommend keeping the fruit from ripening because the plant can become very weedy in the greenhouse setting.

Propagation: Hippobroma longiflora are easily propagated from cutting or by seed. Seed germinate in 7-14 days at 65° F.

Hippobroma longiflora was featured as Plant of the Week July 6-13, 2001.
