Horticultural Information
Intro: Low-growing, carnivorous perennial found in mountain bogs and fens, seepage slopes, vertical seepages on rock or clay, and in northern parts of our range in Coastal Plain wetlands.
Stems: Stems are slender, smooth flowering scapes that emerge from a basal rosette of leaves.
Leaves: Leaves basal (rosette about 4 in. wide), on flattened petioles, nearly round and covered with red, gland-tipped hairs that attract and trap insects.
