Allamanda brings bold, golden-yellow trumpet-shaped blooms to the garden, and with the right support and care it makes a dramatic climbing or sprawling feature.
Sun and Soil Needs
Allamanda wants full sun and rich, well-drained soil to produce its heaviest flush of blooms. Too much shade results in a leafier plant with fewer flowers.
Support and Training
As a vigorous vine, allamanda benefits from a trellis, fence, or arbor to climb. Regular tying-in of new growth helps train it into the shape you want.
Watering and Feeding
Consistent watering during the growing season supports strong blooms, and a regular feeding schedule with a bloom-boosting fertilizer keeps the flowers coming.
Pruning and Winter Care
Prune after major bloom flushes to control size and shape. In cooler parts of Florida, allamanda may need protection or may die back in a hard freeze, typically returning from the roots in spring.
