One of the best ways to fight the threat of invasive species spreading across Oregon's lands and waters is to replace them with native (or non-invasive) plants or, better yet, never plant them in the first place.

To help your efforts at home and elsewhere, here's a list of invasives still commonly sold as ornamentals. Each invasive plant listed is followed by several alternatives.
