''Silene virginica'', the fire pink, is a wildflower in the pink family, Caryophyllaceae. It is known for its distinct brilliant red flowers. Each flower is approximately five centimeters in diameter and composed of five notched, brilliant red petals which extend into a long tube. It is a small (20-80 cm tall), short-lived perennial (2-3 years), with lance shaped leaves. Its stems, and the bases of the flowers, are covered in short sticky hairs.〔(Flora of North America: Silene virginica )〕 Fire pink begins blooming in late spring and continuing throughout the summer. It is sometimes grown in wildflower, shade, and rock gardens.〔(Missouri Botanical Garden Center for Home Gardening: Silene virginica )〕
