CARA Category 3
NEMBA 1a

This herbaceous perennial derives from Central and south-eastern United States and belongs to the Asteraceae family. It grows in small clumps but forms extensive colonies, reaching little more than half a metre in height. It has leaves that grow to about 7-11cm in length, opposite, and sometimes alternating near the top where the leaves are fewer. Flower heads are yellow, and are between 3 and 4cm across and occur between October and December.

Why is it a problem?
It competes with, and has the potential to replace, indigenous species.
Control method
This invasive can be controlled by manually uprooting it, mowing it, transforming the land and by applying herbicides, which are available, to it. No biological control has been introduced in South Africa as yet.
Where is it a problem?
KwaZulu-Natal
