If you have ever seen the blooms of the onion and the garlic, you might recognize their relation to the allium. The globe flower shape is easily identified, even in allium's varied shapes and colors. A. giganteum --tallest of the group-- has flower stalks 3 to 5 feet tall over a base of foliage. Flowers are purple and appear in early summer. A. rnoly is about 2 inches tail with golden-yellow flowers in midsummer. Drumstick allium (A. sphaerocephalurn) produces giant red blooms on 2-foot-tall stalks. A. karataviense is silvery pink in late spring.
