Perennial sweet pea


  • This plant has a Plant Risk Evaluator rating of High Potential Risk


Perennial sweet pea, sometimes called everlasting pea, has a vining habit growing up to 9 ft. It has blue-green foliage and its flowers are usually red, purple, white, and/or pink. It grows with little care and is moderately drought tolerant. Can spread by seed and through its large rhizome network. Native to Europe, it may escape and become naturalized. In fact, it has naturalized in the Mediterranean region, northern and central Europe (in places where it is not native), Australia, and parts of North America. Specifically, this species has naturalized in 43 counties of California.

Why is this plant not included on the invasive plant list?
