Alliums are plants of exquisite beauty in both flower and leaf, with tough constitutions. These easy-to-grow plants come in a broad palette of colors, heights, bloom times and flower forms. They make excellent cut flowers for fresh or dried bouquets. Even crowded gardens can accommodate a few alliums because they don't take up much space. What's more, alliums are relatively resistant to deer, moles, chipmunks, and rabbits.
