Allamanda cathartica (Kaha Mal)

  

Golden trumpet or allamanda cathartica is a flowering plant commonly seen as a landscape ornamental in tropical locations. These beautiful plants with large, fragrant, deep golden yellow flowers are Allamanda cathartica, a member of the dogbane family. 

Allamanda flowers primarily in the summer and fall. The large (to 5 inches across), trumpet shaped blossoms are composed of 5 large overlapping petals, that flare widely. There are both single and double forms. The clusters of flowers occur at the tip of new shoots. There can be one to several flowers in each cluster. When pollinated, green, spiny, round seed capsules may follow the flowers. Hummingbirds will visit the flowers.
