Combretum grandiflorum

Combretum grandiflorum is a showy tropical vine that will reach 20 feet in the greenhouse setting. It is a native of Gambia, Guinea and Ghana in West Africa.

Blooming Time: Summer. The showy red flowers are 1 inch across and 1½ inch long. Panicles of flowers often reach 12 inches across in cultivation.

Culture: Combretum grandiflorum needs full sun to partial shade with intermediate to warm temperatures. In the greenhouse, we grow ours under 40% shade all year. The soil consists of 2 parts loam to 2 parts peat moss to 1 part sand. The soil should be kept moist at all times. Fertilize monthly during the growing season with a balanced fertilizer. Since the vines grow to 20 feet, they need a lot of room to grow. If the plant gets too large, it responds well to trimming to keep it at a manageable size. This is best done in late winter before new growth starts. Keep spent flowers trimmed off.

Propagation: Combretum grandiflorum is easily propagated from cuttings or by layering in early spring. It is easily started from seed. Seeds germinate in 7 to 21 days at 70 degrees.

Combretum grandiflorum was featured as Plant of the Week August 25-31, 2000.
