IDENTIFICATION — Often sold as an ornamental, the leaves of chameleon plant are green with margins of red, bronze or yellow and have a pungent odor when they’re crushed. The plant reaches 6 to 12 in. tall and spreads by underground rhizomes, rooting stems and seeds.
FAVORITE CONDITIONS — It prefers wet soil in sun or shade; in dry shade situations it spreads much slower.
CONTROL — Start digging and keep digging or spray with a nonselective herbicide. If you want to keep some, plant it in a buried container so the roots can’t run.
