How to grow

Cultivation

Normally started from clusters of claw-like tubers, planted in autumn or spring, and requiring a dry, dormant period in summer. Grows best under unheated glass with good light and ventilation, using a fertile, humus-rich, free-draining compost such as a mix of equal parts loam, leaf mould and grit. Can also be used as a short-term bedding plant in well-drained soils
