Allium Ornamental Onion

Alliums, normally considered an essential food source, are greatly valued for their aesthetic interest. The genus has approximately 500 species which are either derived from bulbs or rhizomes. All emit an odor, from mild to strong, that we are all cognizant of. Onion species can range in size from 2-3" tall up to 48" tall making them suitable for the front or back of a perennial border. The varied flowers are formed on umbels above leafless stalks and appear in colors of white, pink, purple, and yellow. They are great for massing in sunny, well-drained garden beds. As summer sets in many alliums go dormant opening the door for other perennials to shine.
