Baccharis halimifolia is an underused, fantastic shrub. It can be used as a perennial (cut it back every year) and it can also be a shrub (no cutting back)! It is salt tolerant and an excellent plant for the hell strip (the space between the sidewalk and the street). Groundsel is a dioecious plant, so you need a male for the females. The best way to do this is to purchase in the fall when they are in flower.
Maintenance: If necessary, you may cut the plant back each year to control the height. The seeds are wind-dispersed.
Benefits: Salt tolerant, drought tolerant, host plant to several moth species, and an excellent nectar source for late-season pollinators, great cover for birds
Fun Facts: Leaves are poisonous to sheep, and female seeds are poisonous. In Southern Louisiana, it has traditionally been used to treat inflamed kidneys.
