Allamanda, Golden Trumpet, Brown Bud Allamanda
Spectacular in bloom, Allamanda cathartica (Golden Trumpet) is an evergreen tropical shrubby climber boasting deep golden yellow trumpet flowers, 5 in. across (12 cm), over a long season. Blooming in succession for months throughout the summer to the first frost – all year in tropical conditions, the fragrant blossoms may be single or double. They may display white markings in the throat, and are produced in clusters. Opening from fuzzy brown buds, they shine against the handsome foliage of glossy, leathery, wavy-margined, bright green leaves, 4-6 in. long (10-15 cm), held in whorls along the stems. Grown as a vine or pruned into a bushy shrub, Allamanda blooms on new growth. Since Golden Trumpet does not twine nor have tendrils, if grown as a vine it must be trained onto a trellis or other support structure. It does not tolerate cold and needs heat for adequate growth and flowering. This tropical plant needs warm conditions with day temperatures of 70ºF (21ºC) or higher and night temperatures of 60-65ºF (15-18ºC). Providing quick, long-season color, Allamanda can be planted outdoors in the mildest climates. Elsewhere, it will happily reside in a container to be moved indoors in cold weather.
