Summary of Invasiveness

Top of page

The following summary is from Witt and Luke (2017):

Description

Large shrub (to 4 m tall); sometimes branching from the base; exudes copious amounts of milky sap when damaged.

Origin

China, Iran, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Pakistan, Sri Lanka and Thailand.

Reason for Introduction

Medicine and ornament.

Invades

Roadsides, disturbed land, wasteland, urban open spaces, fallow land, croplands, gullies, lowlands and floodplains.

Impacts

C. gigantea occurs sympatrically with C. procera in many parts of Kenya and Tanzania. As such, their impacts may be considered to be similar. Invades degraded rangeland pastures, river flats and coastal dunes.
