Perennial rhizomatous insectivorous herbs, generally without stems. Leaves take the form of rosettes of pitcher-like traps that are ridged on one side and often with a lid-like flap on the top; stipules absent. Flowers bisexual, bent over, on stems arising from the centre of the rosette, generally with 5 free petals and sepals; stamen number variable but more than twice as many as the petals. Carpels (3)-5, united. Ovary superior, ovule placentation axile. Fruit a capsule.
Plants grow naturally in nutrient-impoverished marshland.
Pitchers all possess some degree of carnivory. Insects and small animals are attracted to the mouth of the pitcher by chemical and colour attraction, and by window-like translucent zones; inside there are backward-projecting hairs that assist in insect capture and retention.
The insect eventually drowns and is digested by the action of bacteria (Darlingtonia, Heliamphora) or enzymes (Sarracenia).
Pitcher plants were available in Europe in the 19th century. In Australia, however, they did not become available to the general public until after 1970 when Steve Clemesha imported seed from the USA and grew them successfully. A rapid succession of growers in the 1980s included Jenny Brownfield, Stephen Jackson and Gordon Cheers, followed by professional nurserymen who turned their skills to mass-production using techniques such as tissue culture.
Flowers bisexual (cf. Nepenthaceae); leaves pitcher-like, arranged in a basal rosette.
