Beaumontia is a small genus of evergreenwoody vines in themilkweed family. It is native toChina, theIndian subcontinent, andSoutheast Asia.[2][3][4]
Beaumontia plants are often rampant climbers andvines. They are mostly evergreen, though in subtropical gardensBeaumontia grandiflora loses many leaves in winter. Leaves are large, smooth and opposite with sticky white sap from petiolar glands.
The large white fragrant flowers are borne incorymbs 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 (seed capsules) comprises a pair of thick woody follicles. The seeds are compressed, apex gradually narrows with a silky coma (a tuft of hairs).[5]
The genus wascircumscribed byNathaniel Wallich in Tent. Fl. Napal. on page 14 in 1824.[6]
The genus name ofBeaumontia is in honour of Diana Wentworth Beaumont (1765–1831), who was an English gardener and married to ColonelThomas Richard Beaumont (1758–1829) ofBretton Hall,Wakefield, Yorkshire. She had an estate with massive dome-shaped glasshouse for exotic plants at Bretton Hall.[7]
TheBeaumontia species are cultivated asornamental plants, withBeaumontia grandiflora widely grown by thenursery trade. They prefer good soil, adequate water and hot moist conditions. They are found planted and trained as vines insubtropical climate gardens, such as inSouthern California.[8][9]
They are propagated from seed or half-hardened cuttings taken with a heel, rooted in sandy soil under mist.[10]
