Allamanda cathartica or Golden trumpet 70 – 90cm

Allamanda cathartica or Golden trumpet is a tropical twining vine with deeply veined, whorled leaves and large, trumpet shaped bright yellow flowers. Prickly seed pods follow the flowers with winged seeds that fly about when the pod dries and breaks open. Allamanda is perennial in tropical climates and may be treated as an annual or brought inside during cold weather and replanted after danger of frost. The plant has milky sap and is considered poisonous; all parts are highly cathartic (hence the botanical name). Texture is coarse and leaves are bright to light green; the plant is often pruned and used as a shrub. Some cultivars have been bred for fragrance; a particularly popular one has furry brown buds and darker green leaves than the species.
