How to Grow

Cultivation

Plant 15cm deep in late summer or early autumn in a warm, very sunny position, such as in front of a south-facing wall, in very well-drained soil, and leave undisturbed unless they start producing fewer flowers. In an alpine house or bulb frame, grow in full light in equal parts loam, leafmould and sharp sand, and water moderately when in growth, gradually reducing water as the leaves die back and the bulb becomes dormant

Propagation

Propagate by division of offsets from large clumps when dormant in summer
