Baccharis halimifolia Salt Bush, Groundsel Bush1

Edward F. Gilman2


Salt bush is native to coastal and interior wetlands and is most often seen invading this type of landscape (Fig. 1). It is often seen in its native habitat with wax myrtle in wet sites. The whitish flowers and fruits bring this rarely-noticed plant into view in the fall landscape. The 2-inch-long leaves and shrubby habit allow it to blend into the background in most landscapes. Seeds are poisonous if they are eaten.

Use and Management

Salt bush is rarely planted by designers and horticulturists, perhaps because it is too 'common' in native stands. A useful shrub or small tree for reclaiming wet sites, Salt-bush could be used more frequently near retention basins and drainage ditches. It has a good tolerance to brachish water. It is well suited for planting in wet sites throughout the state. With proper care to remove recurring dead wood, nice small-tree specimens can be created. These can become nice additions to many landscape. They come into flower and are attractive at a time when few other small trees and shrubs are flowering.

Pests and Diseases
