Plant Details

From Tropical South and Central America. These plants have striking foliage and trumpet-shaped flowers (borne nearly year-round). Plant permanently outdoors only in the mildest climates. Elsewhere, grow as summer-blooming potted plants; keep indoors during cold weather. They tolerate very little frost and need heat for proper growth and bloom; warm nights and warm days are necessary. Remove spent flowers for increased bloom.

A. blanchetii (A. violacea). PURPLE ALLAMANDA. Shrubby or with a few vining stems; usually grows 610 ft. tall and wide. Leaves are somewhat downy and up to 5 in. long. Rose-purple flowers are 3 in. across. 'Cherries Jubilee' has brilliant burgundy-red blooms.

A. cathartica. ALLAMANDA, GOLDEN TRUMPET. 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, 46 in. long. Yellow trumpets are 5 in. wide, 3 in. long. 'Chocolate Swirl' have pinkish-purple flowers with purple-brown throats. 'Flore Pleno' bears double flowers. 'Hendersonii' bears exceptionally attractive orange-yellow blooms.

A. schottii. BUSH ALLAMANDA. Shrubby growth to 46 ft. high and wide; produces occasional climbing stems. Flowers are 3 in. wide, bright yellow, sometimes with throats tinted orange or reddish.
