‘Ray’s Golden Campion’ red campion (Silene dioica) is a beautiful biennial or short-lived perennial for the early-season garden in full sun to partial shade. Its dense mounds of vibrant yellow leaves send up 1- to 2-foot-tall, branching stems that carry an abundance of bright pink flowers from early or mid spring through late spring. Some plants produce only male flowers (these tend to bloom a few weeks longer, into early summer); others produce only female flowers (these produce seed if you also have male plants). Red campion tends to act like a biennial or a short-lived perennial. It is reportedly hardy in Zones 5 to 8.
I collected these seeds in mid-June 2020, from golden-leaved plants growing at least 20 feet from any green-leaved Silene dioica. Even with that, it is likely that some of the seeds will produce green-leaved plants, which I recommend removing and discarding if you want to try to keep the strain as golden as possible. Each packet contains at least 25 seeds.
