They are highly branched plants of shrub, climbing or arboreal bearing that reach 10 meters (32.8 feet) in length. The leaves are lanceolate, leathery in texture and deep green in color. The interesting and curious flowers are scented and yellow with red spots. They bloom in spring.

They can be used as isolated specimens (tree), in groups or informal hedges (shrub) or as climbing plants to cover walls, fences or pergolas.

Strophanthus speciosus grow in full sun or semi-shade exposure and in hot climates. They do not resist temperatures below 5 ºC (41 ºF).

They prefer well-drained soil; for example a normal garden soil with coarse sand and organic matter.

Water regularly so that the soil is always slightly damp; never flood.

Fertilize with compost or manure in late winter or fall.

Prune lightly after flowering to maintain a compact appearance.

If they suffer prolonged drought they can be attacked by aphids.

They are propagated from seeds sown in spring in a porous substrate or by cuttings in summer or spring.
