How to Grow

Cultivation

Grow in a bog garden, or outdoors in containers of specialist carnivorous compost, in full sun. In summer stand containers in trays of lime-free water and irrigate only with rainwater. Sarracenia require a period of winter dormancy when they should be kept moist, cool, and well ventilated; an unheated greenhouse is ideal. See carnivorous plant cultivation

Propagation

Propagate by division in spring
