Invasive Plant List

Invasiveness depends on your location

Plants may be invasive in some regions of California, and not invasive in others. This map shows you the California regions used by our list. The plants listed below are invasive in one or more regions as shown on this map.

How are these regions determined?

The regions shown on this map are based on the Sunset Climate Zones, which are determined by an area’s rainfall, temperature range, 风, 湿度, and length of growing season.

These are the Sunset Climate Zones which correspond with each region:

  • 塞拉 and 海岸山脉: Sunset Zones 1-3
  • 中央山谷: Sunset Zones 7-9
  • 沙漠: Sunset Zones 10-13
  • 北 and 中央海岸: Sunset Zones 14-17
  • 南海岸: Sunset Zones 18-24

工厂看

Many plants we consider for the list of invasive list meet some but not all of the invasive list criteria. These are the plants we refer to as “工厂看.” We provide more details about these plants, why they aren’t on the plant list, and if there are places in California where this plant should be avoided.
