Cal-IPC's "Don't Plant A Pest!" Brochure

Invasive plants are by nature a regional or local problem. A plant that jumps out of the garden in one climate and habitat type may behave perfectly in another. This website is organized by region, so you can learn which plants are most problematic in your area, and what alternative plants make good replacements. There is also a California-wide guide to alternatives for invasive trees.
