Yellow Allamanda Allamanda cathartica

Allamanda cathartica, or Allamanda, is a genus of tropical, tender, perennial evergreen. There are 15 species of Allamanda found in South and Central America and commonly grown in gardens throughout the tropics, where some species have become naturalised and even invasive. In temperate countries such as the United States, 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.

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.
