Silene chalcedonica

A clump-forming perennial herb native from eastern Europe to Siberia and China, it sends upright leafy stems above a basal crown. Dense terminal clusters contain many brilliant red flowers, each divided into deeply notched lobes around projecting stamens. Opposite lance-shaped leaves occur in pairs along the sturdy stems. It reaches about 3 feet tall. Plants can be propagated by seed, division or basal cuttings. Photographed in Florida.
