Don't Plant a Pest

Southern California region

The problem plants listed here can escape from gardens in the Southern California region and invade wildlands (see photos under each plant listed). Because of their aggressive growth, these plants degrade native habitat, and some increase flood and fire risk. Each section lists other desirable landscaping plants that serve as good alternatives to the invasive plants

Select a type of plant below for a list of invasive species and alternatives.
