How to grow

Cultivation

Plant 15cm deep in late summer or early autumn in an alpine house or bulb frame 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; outside, grow 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 produce fewer flowers

Propagation

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