Alliums belong to the onion family, so they are just as easy to grow and long-lived as chives or any other perennial onion. They will tolerate poor, dry soil, they are deer resistant, and they can be left undisturbed for years and years and will multiply. Alliums make a very strong and long-lasting cut flower. If left in the garden, the seed pods give a textural interest well into fall and even winter. Zones 3-8.
