Common Names

Origin

Native to Africa (i.e. Angola, Benin, Burundi, Cameroon, Chad, Djibouti, Ethiopia, Gabon, Ghana, Guinea, Guinea Bissau, Ivory Coast, Kenya, Malawi, Mali, Mozambique, Nigeria, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Tanzania, the Gambia, Togo, Uganda, Zaire, Zambia and Zimbabwe) and Mauritius.

Naturalised Distribution

Naturalised in many parts of northern Australia. It is common in northern and central Queensland and in the northern parts of Western Australia and the Northern Territory. It is less common in south-eastern Queensland and the north-western parts of Western Australia, and is also naturalised on Christmas Island.

Also widely naturalised throughout the humid and sub-humid lowlands of Asia, on several Pacific islands, in the Caribbean, Central America and South America, and in the southern parts of USA (i.e. Florida, Georgia, Texas and California).

Notes

This pasture legume (and occasional garden ornamental) has escaped cultivation and invades river banks, creek lines, the margins of waterholes, irrigation channels, disturbed sites, waste areas, roadsides and disturbed natural vegetation (i.e. open woodlands and grasslands).

Butterfly pea (Clitoria ternatea) is regarded as an environmental weed in Western Australia and the Northern Territory, and is also seen as a potential environmental weed in northern Queensland. It is actively managed by community groups in the Northern Territory, and is of most concern where it has invaded riparian zones within conservation areas near Darwin. It has also been listed as a priority environmental weed in one Natural Resource Management region in northern Australia.
