A carnivorous bog plant that has violet flowers borne above a rosette of yellowish-green greasy leaves that trap and digest small insects. It is native to both Eurasia and North America.
Genus Pinguicula, family Lentibulariaceae: several species, in particular the common butterwort (P. vulgaris)‘Skylarks sang over the wetlands, carnivorous butterworts were in violet flower and cotton grass fluffed up the land.’
- ‘The violet flowers of butterworts nod manically at the roadside, seeming too delicate for this windswept terrain.’
- ‘There are many more plants that will thrive in medium light, among them Irish moss, Tahitian bridal veil, heart-leaved philodendron, pitcher plant, and butterwort.’
- ‘Commonly called the butterworts, these plants are just about the most innocuous-looking carnivorous plants you'll ever see.’
- ‘The insect-eating common butterwort, previously thought to be extinct in the region, has also been noted.’
Late 16th century named from the plant's supposed ability to keep cows in milk, and so maintain the supply of butter.
