|Asystasia gangetica (L.) Anders.|
Chinese violet is a rapidly growing perennial, shrubby herb which grows to 1 m height but can grow over shrubs up to 3 m tall. It can smother all vegetation in the herbaceous layer. The seeds are dispersed from explosive capsules but long-distance dispersal is effected by man. Although aerial portions may be killed by fire, the plant soon regenerates from basal shoots or seeds. It has not been evaluated for biological control.
Chinese violet grows in dry habitats between sea level and 300 m on all islands. There are dense infestations at Lualualei, 'Ewa Plains, Diamond Head, and Koko Head, O'ahu.
