Notes
Purple allamanda (Allamanda blanchetii) is an evergreen shrub for container growing. It grows outdoors year-round in USDA zone 9 and warmer, down to about 20°F (-7°C). In colder areas, grow it as a houseplant or bring it indoors for winter. This plant likes full sun and average to moist soil of most types. It can reach about 6 to 10 feet tall and wide, so give it a big pot.
Pairs well with Flowering banana, Lemon grass, and Creeping fig.
