Sales of Tropical Milkweed are no longer allowed in any nursery or retail center in Ventura County. On June 1, 2022, the Ventura County Agricultural/Weights & Measures Office received notice from the California Department of Food and Agriculture that tropical milkweed (Asclepias curassavica) has been designated as a destructive weed (B-rated noxious weed). Residents who would like to remove tropical milkweed from their properties are encouraged to do so. California Native Milkweed is a good alternative that supports habitats for pollinators like Monarch butterflies.
