Common names: Common calpurnia, Wild laburnum, Natal laburnum, Cape laburnum. This species is native to South Africa.

They are trees or shrubs of elegant bearing and open crown that reach 4 meters (13.12 feet) in height in the gardens. The odd-pinnate compound leaves are formed by light green leaflets. The abundant and showy yellow flowers appear in hanging clusters. They can bloom in summer and again in fall. The fruits are light brown pods.

These easy-to-grow, fast-growing plants are used as isolated specimens on lawns, in rockery, in pots or in bushy groups. They are ideal for Mediterranean coastal gardens.

They prefer well-drained soils with organic matter. The transplant is done in spring.

They need regular waterings always waiting for the soil to have dried.

Prune after flowering to maintain a compact appearance and favor the next flowering.

They are quite resistant plants to the usual pests and diseases.

They propagate easily from seeds soaked one day and sown during spring or early summer.
