family

Asteraceae (daisy family)

status

Groundsel bush (Baccharis halimifolia) is listed as noxious in class 3 in Bega Valley, Eurobodalla, Illawarra and Shoalhaven LCAs, although to date it is confined to the northern part of the region.

Description

A perennial shrub 1-6 metres high, with striate (grooved) stems, hairless and sticky. Leaves are alternately arranged on the stems, with coarsely toothed edges in the upper half, the leaf size reducing towards the top of each stem and the upper leaves with untoothed edges. Flowers are small (3-5mm diameter), white to yellowish, in terminal clusters. The seed has a cluster of fine hairs which help it to disperse on the wind. Thanks to Sheldon Navie of the University of Queensland for the photos of this weed.

Preferred habitat

A weed of saline areas on the coast, growing in situations such as along the back edge of mangroves, in swampy areas and low-lying pasture, north from the Illawarra and in the Sydney area.

Dispersal

Seeds are spread by wind and possibly water.

Look-alikes

No very similar species occur in the area.

Control

Hand-pull seedlings. Cut and paint adult plants.
