An invasive plant is a plant that is non-native to the ecosystem under consideration, and whose introduction is likely to cause economic or environmental harm, or harm to human health.
Invasive plants harm California’s environment and economy in many ways. They can overtake crops or rangeland; harm wildlife by eliminating plants they need for food and shelter; clog waterways used for commerce or recreation; and increase fire hazards and flood risk.
There is no shortage of superior alternatives. The vast majority of garden plants are well behaved and will never become an invasive problem. Our plant list includes several suggested alternatives for each invasive plant.
Be a part of the solution by planting right. Whether you are a retail nursery, grower, landscape professional, or home gardener — everyone can play a critical role in preventing the spread of invasive plants.
From our original invasive plant list of 19 species, just seven are still commonly available for retail sale in California. When you avoid buying these plants, you help protect California’s environment for recreation, farming, and wildlife.Avoid these plants!

“By choosing non-invasive plants, we are not only being good stewards of the environment but creating lower-maintenance landscapes, which makes life easier for landscapers and reduces long-term costs for clients.” — Maureen Decombe (Past President, APLD-California Chapter and current Sustainability Chair)
PlantRight has been a part of removing more than a dozen highly invasive plants from retail stores across California, helping prevent their spread and reintroduction into natural areas.See the list of "retired" plants here.
