Hybanthus communis, a native of Eastern Brazil and Paraguay, is a perennial herb that reaches 3 feet tall in containers. It occurs along forest edges and roadsides.
Blooming Time: In the greenhouse, they bloom from late fall to early spring. The white flowers are tinged with light purple and a yellow spot in the center of the lower petal. They last only one day.
Culture: Hybanthus communis need warm temperatures and partial shade. We grow ours under 52% shade all year long. A suitable soil mix consists of 2 parts peat moss to 2 parts loam to 1 part sand or perlite. The soil should be kept moist for optimum growth and flowering. Fertilize every other week with a balanced fertilizer diluted to ½ the strength recommended on the label. They are prolific seed producers and spent flower heads should be removed to keep the plant from becoming weedy.
Propagation: Hybanthus communis are propagated by cuttings or by seed. Seed should be surface sown and will germinate in 7-14 days at 70° F.
Hybanthus communis was featured as Plant of the Week January 4-10, 2002.
