About this species

Hopbush is a highly variable evergreen shrub or small tree with several subspecies and varieties. It occurs around most of the southern hemisphere, and its numerous useful properties have been discovered independently by people of different continents. The flowers are relatively unspectacular but its winged fruits can become red or purple as they mature, making it an attractive garden plant in the tropics and subtropics. One cultivated variety also develops purple leaves when grown in direct light. The scientific name, Dodonaea, refers to Rembert Dodoens (a 16th century Flemish royal physician, botanist and professor), viscosa to the stickiness of its leaves.

Genus: 
Dodonaea
