How to grow

Cultivation Grow in a cool glasshouse or bulb-frame in a mix of equal parts loam, leaf mould, peat substitute and sharp sand. Plant with the tops of the tubers just at the surface. Provide bright, filtered light and moderate humidity. Water moderately when in growth but reduce humidity and water as the leaves fade. Keep completely dry when dormant. Apply a low-nitrogen liquid fertiliser every two months when in full leaf. See hardy cyclamen cultivation

Propagation Propagate by seed, sown in darkness as soon as ripe. Can be beneficial to soak seed for 10 hours prior to sowing
