verifiedReviewed by the GreenScout Team

A striking biennial or short-lived perennial with velvety gray-green foliage and brilliant magenta (or occasionally white) flowers that bloom in mid-summer on tall, branching stems. Also called Rose Campion, Lychnis adds bold color and textural interest to borders and self-seeds readily, creating naturalistic drifts. It is extremely hardy, drought-tolerant, and attractive to pollinators.
