Grow allamanda in full sun and moist, well-drained soil to keep it happiest. Allamanda will grow in partially shaded spots, but it won't bloom as well. Because this flowering shrub is drought tolerant, it's an excellent choice for low-care landscapes. Even though allamanda is drought tolerant, it's best to keep it well watered the first couple of months after you plant it to help it get established. The best time to prune most allamanda varieties is mid-spring, before they start to bloom. You can trim them back here and there any time of the year, but doing heavy pruning in spring should help give the best display of blooms.
- Light Needs: Full sun
- Watering Needs: Medium water needs
Allamanda is an easy-to-grow flowering shrub from the tropics that offers a steady display of golden-yellow flowers all spring and summer long. It's prized for its excellent heat tolerance and long-season bloom -- as well as the fact that allamanda grows well in both containers and landscapes. Grow allamanda in containers either by itself, with other tropical plants (such as elephant's ears), or with heat-loving annual flowers such as angelonia. (We think its yellow flowers are a wonderful accent to plants that have purple flowers or foliage!) In frost-free climates, large allmanda varieties are grown as vines or hedges (depending on the type). Dwarf allamanda varieties are excellent small hedges, or to line sidewalks or walkways.
