Grow in full sun and fertile well-drained soil. It is best to grow in containers where garden soil is heavy clay and prone to saturation over winter. See allium cultivation
Propagate by seed, sowing in containers in a cold frame when just ripe or in the spring and by offsets which can be carefully detached by lifting the bulb after flowering has finished. See bulb propagation
No pruning required, other than to remove old flowered stems and foliage
