Allamanda & Mandevilla
- Overview - Aggressive growers as vines or shrubs. Beautiful yellow, purple or white flowers that bloom in Summer and Fall. Most varieties are poisonous and can cause skin or eye irritation. While the plants will thrive in Central Florida, they are cold sensitive, so consider using containers.
- Vine Allamanda (allamanda cathartica) Prefers sun. Large yellow flowers. Aggressive grower as a vine, requires support, not for a confined area like a mailbox or container. Can be trained as a shrub.
- Bush Allamanda (allamanda neriifolia and allamanda schottii ) Loosely formed shrub to 6'. Yellow blooms in Summer and Fall. Grows best in full sun. Since it prefers Zones 10b and 11, the plant can be grown in a container for Zone 9. Pinch branches for best flower display.
- Purple Allamanda (allamanda violacea or allamanda blanchetii) Purple flowers. Can be trained to cover mail box or small trellis or left to cover an entire arbor. Can be pinched back to keep form. Prefers Zones 9b to 11, so it is better suited to Central Florida than Bush Allamanda. The India Rubber Vine (cryptostegia grandiflora or cryptostegia madagascariensis) is also referred to as Purple Allamanda.
- Bolivian Allamanda (allamanda bolivinensis) Large white flowers with yellow throats.
