What You Need to Know About the Mandevilla – Apocynaceae (syn. Dipladenici)

This genus of wood climbers, known as Brazilian jasmine, support themselves by winding their stems around a support. The leathery, glossy, mid ­green leaves, borne in pairs, are up to 2 in. (5 cm) long. Throughout late spring, summer, and early fall, clusters of 3—5 flowers appear on the new growth. They are large and showy, being trumpet-shaped, up to 3 in. (7 cm) across.

M. x amoena ‘Alice du Pont’ is rose pink and M. sancleri is also rose-pink with a yellow throat. M. s. ‘Rosea’ has larger leaves, bronze beneath, and flowers, to 3 V, in. (8 cm) across, of salmon-pink with yellow throats. The flowers are produced when the plant is still young, and regular pinching can be used to encourage a bushy plant rather than a tall one.

Size: Spread up to 10 ft. (3 m) if left unpruned.

Light: Indirect sunlight.

Temperature: Normal room.

Moisture: Keep moist from spring to fall. In winter, apply only enough water to prevent the soil mix from drying out.

Feeding: Give standard liquid fertilizer every two weeks in spring and summer.

Propagation: Take tip cuttings, 4 in. (10 cm) long, from new growth in spring. Root at 75—80°F (23—25°C).

Special needs: Flowers are only produced on the current year’s growth, so do not prune until fall, then cut back most of the newest shoots to encourage the production of more the following spring.
