Synonyms[1]

Beaumontia is a small genus of evergreen woody vines in the Apocynaceae. It is native to China, the Indian Subcontinent, and Southeast Asia.[2][3][4][5]

Description

Beaumontia plants are often rampant climbers and vines. They are mostly evergreen, though in subtropical gardens Beaumontia grandiflora loses many leaves in winter. Leaves are large, smooth and opposite with sticky white sap.

The large white fragrant flowers are borne in corymbs terminal and in the leaf axils. The calyx is 5-lobed and the corolla is dark funnel-or bell-shaped with 5 lobes. Stamens are attached near the base of the corolla tube and have slender filaments with arrow-shaped anthers. They are very showy when in full bloom and are regarded as among the most outstanding vines of the world.

The fruits comprises a pair of thick woody follicles.

Cultivation

The Beaumontia species are cultivated as ornamental plants, with Beaumontia grandiflora widely grown by the nursery trade. They prefer good soil, adequate water and hot moist conditions. They are found planted and trained as vines in subtropical climate gardens, such as in Southern California.[6][7]

They are propagated from seed or half-hardened cuttings taken with a heel, rooted in sandy soil under mist.[8]
