Senegal Tea Plant

Senegal tea plant (Gymnocoronis spilanthoides ) is declared noxious in the Illawarra District Weeds Authority control area (including Kiama, Shellharbour and Wollongong council areas).

The weed control class is 1. This means that:

“The plant must be eradicated from the land and the land must be kept free of the plant”.

Description: An aquatic perennial that grows across the water surface in wet marshy areas. It has a variety of forms. It produces runners and floating stems to 2.5 metres in height, or may grow as a rounded bush. The shiny dark green leaves grow 5-20 cm long, with serrated margins. The stems have hollow nodes which allow the plant to float. Young stems are light green with dark green blotches along them.

Problem: It is an aggressive invasive plant capable of growing up to 15 cm per week. It can propagate from leaf fragments. Dense mats can block waterways. Could have a major impact on native wetlands.

Control: Must be reported to the Local Control Authority. Seek their advice.
