Lychnis (lik-niss,) campion catch fly; Caryophyllaceae Family. Lychnis is a large genus of annuals, biennials and perennials native to the North Temperate Zone regions. Many have truly beautiful flowers with bright colors. All have opposite leaves.
Lychnis is grown best in full sun or light shade in a moderately rich, well-drained soil. They are fine plants in the border as well as useful all summer as cut flowers. With their long bloom season, late June to frost, and their ease of culture their popularity is understandable.
