The common butterwort, also known as bog violet or marsh violet, can be found in damp areas such as bogs, fens, wet heaths and rock crevices. Due to its low-nutrient habitat, the common butterwort has evolved into a carnivorous plant that supplements its diet with insects.
Common butterwort has a long, slender stem which grows up to three funnel-shaped purple flowers. These attractive purple flowers entice insects to land on the star-shaped cluster of yellow-green leaves at the base of the stem. The leaves secrete a sticky fluid which traps the common butterwort’s prey, then close and digest the insect.
Height: 10 cm – 20 cm
