How to Grow

Cultivation

Under glass, grow in mix of equal parts fertiliser-free peat substitute and sand, in full light with shade from hot sun. The compost should be kept continually moist in the growing season by standing the container in a tray of soft (lime-free) water, such as rainwater. During the winter, plants enter a period of dormancy so keep plants moist, not sodden. Outdoors grow in wet, naturally peaty, acidic, nutritionally poor soil in full sun. See Carnivorous plant cultivation

Propagation

Propagate by sowing seed as soon as ripe, or by root cuttings when dormant
