Allamanda cathartica

Allamanda, Golden Trumpet
Evergreen, Shrubs, Vines


These handsome plants from tropical South and Central America tolerate very little frost and require considerable heat for proper growth and bloom; warm nights as well as warm days seem necessary. Trumpet-shaped flowers (borne nearly year-round) and foliage are both imposing. Permanent outdoor plants only in the mildest climates. Elsewhere, grow as summer-blooming potted plants; keep indoors during cold weather.

Allamanda cathartica

Can grow to great heights (over 50 ft.) as a vine; it can clamber through trees but must be tied to other supports. Often pinched back to grow as a large freestanding shrub. Leaves are glossy, leathery, 4–6 in. long. Yellow trumpets are 5 in. wide, 3 in. long.
