Allamanda cathartica

Golden Trumpet Vine

Allamanda are popular as ornamental plants cultivated for their large, colourful flowers. Most species produce yellow flowers. The flower has five lobed sepals and a bell- or funnel-shaped corolla of five petals. The plants do not tolerate shade or salty or alkaline soils, and they are sensitive to frost. They grow rapidly, sometimes spreading 3 meters per year. They can be propagated from cuttings. A. cathartica has been widely cultivated as an ornamental in tropical and subtropical regions of the world. Individuals are fast-growing plants and spread rapidly by layering. It spreads so rapidly that it is considered an invasive weed in some regions.

Planting young plants

From Early Spring TO Early Spring

Plant young plants in spring in a sunny site. They do not do well in shade. The soil should be acidic or neutral and should be moist and well drained. Do not plant in a waterlogged area. In colder climates, they can be planted in containers which can be brought in for winter protection.
