Sarracenia × harperi

Harper's pitcher plant

A large, evergreen, rhizomatous perennial to around 30cm in height, with rosettes of modified leaf stems called 'phyllodes' which function as insect-catching tubular pitchers with hooded lids. These strong, over-sized pitchers are yellow-green with prominent red veining, turning to bronze in summer

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
