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. Self-seeds freely. See allium cultivation
Propagate by seed when just ripe or in spring; or propagate by offsets which can be carefully detached by lifting the bulb after flowering has finished. See bulb propagation. Deadhead regularly if you do not wish for it to self-seed
No pruning required, other than to remove old flowered stems and foliage
