Genlisea, the corkscrew plants, is a genus of about 30 small carnivorous herbs from wet, semi-aquatic habitats in Africa and Central and South America. Grow them wet, in bright light, in a mix that stays constantly moist; the key is never letting the roots or traps dry out.

About

Genlisea ( JEN-liss-EE-ə) is a genus of carnivorous plants also known as corkscrew plants. The 30 or so species grow in wet terrestrial to semi-aquatic environments distributed throughout Africa and Central and South America. The plants use highly modified underground leaves to attract, trap and digest minute microfauna, particularly protozoans. Although suggested a century earlier by Charles Darwin, carnivory in the genus was not proven until 1998.

The generic name Genlisea honors the French writer and educator Stéphanie Félicité Ducrest de St-Albin, comtesse de Genlis.
