Baccharis angustifolia
 
Common Names Saltwater False Willow, Narrowleaf Baccharis, False Willow
 
Zones 8a–11
 
A tough, upright shrub native to the coastal wetlands and brackish marshes of the southeastern United States, Baccharis angustifolia is valued for its adaptability, wildlife support, and erosion control. Despite its willow-like appearance, it belongs to the sunflower family (Asteraceae) and produces cottony seed clusters in fall. Its tolerance for salt, flooding, and poor soils makes it ideal for restoration and naturalized landscapes.
