Allamanda blanchetii

 

Purple Allamanda

Purple Allamanda is a striking addition to any frost-free landscape. It sports pretty violet-shaded flowers that are trumpet-shaped, very showy and appear all year in consistently warm climates. This vine has thin, arching, twining woody branches. The bark is brown, furrowed on mature stems and yellow-green on younger branches. In temperate climates, allamanda may be grown outdoors in containers during the summer months and brought into a greenhouse or conservatory to over-winter. Allamanda are popular as ornamental plants cultivated for their large, colourful 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.

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.
