Allamanda is a tropical, evergreen, perennial vine in the dogbane family (Apocynaceae). It is native to Central and South America but is cultivated in warm areas around the world. In temperate regions, they are grown as greenhouse plants or houseplants for their freely produced, brightly coloured, golden yellow flowers that contrast with the shiny dark green leaves. The species epithet is Latin for cathartic, in reference to its purgative effect when ingested.

\r\n\r\n

Allamanda forms a sprawling shrub or woody climber that tends to sprawl and twine itself around a support and will need to be tied to a trellis or other support. If grown outdoors in the landscape, the plants should be cut back and overwintered as indoor container plants before the first freeze. Note that, once indoors, the plant requires a site with bright light. Whether indoors or out, the plant does require ample moisture and good drainage.

\r\n\r\n

This plant is suitable for butterfly gardens, rain gardens, and drought tolerant gardens. As a container plant it can be trained on a trellis to work as a screen, or it can be an accent or specimen plant on its own.
