Urechites lutea Wild Allamanda1

Edward F. Gilman 2


Wild allamanda grows as a vine-like shrub when it is young (Fig. 1). Left to its own devices, it develops into a sprawling vine climbing over nearby shrubs, trees, and other structures. In this manner, it is not unlike the non-native allamanda. Yellow flowers about 2 ½ inches across are produced year-round on stem tips. Although the plant is not covered with flowers like the non-native allamanda, there are usually some flowers on the plant all year long.

Use and Management

Wild allamanda can be maintained as a shrub with periodic pruning to check its size. Cut the longest stems back inside the plant so new growth helps keep the shrub full. It makes a nice addition to the native landscape in tropical areas as a specimen, or it can be trained to grow onto an arbor or trellis. The vine will need periodic clipping to keep it from overtaking the trellis. A row of wild allamanda planted several feet apart can be maintained as a low hedge with regular clipping.

Although growth continues in the total shade, wild allamanda will flower best in full sun or partial shade. With tolerance to salty air and drought, it is nicely suited for sandy, coastal landscapes. Plant grow fine in alkaline soil.

Pests and Diseases

There appear to be few problems that limit the growth of wild allamanda.
