Allium Purple Rain bulbs go dormant after flowering so it is important to plant them where you will not disturb them, often they will start to seed around the base of the plant and in time a clump will form, if these become congested then the bulbs can be dug up and moved whilst they are dormant to develop new clumps. If left after flowering the seed heads will dry in the sun and are attractive if left.
