Alliums: A Field Guide
Ornamental alliums—not to be confused with the edible chives, garlic, and onions which also belong to the Allium genus—are versatile perennial flowers with long-lasting blooms.
With purple puffball flowers shaped like dandelions gone to seed, alliums had whimsy and visual punctuation to a flower border. After the blooms fade, leave allium’s seed heads in place to feed the birds.
Some of our contributor Kendra Wilson’s favorite varieties to grow (and to use as cut flowers in floral arrangements) are “sublimely round” Allium hollandicum ‘Purple Sensation’ and smaller, egg-shaped Allium spherocephalon. Not to mention her favorite pink varieties: Allium nigrum ‘Pink Pearl’ or the big ones, such as mega Allium schubertii.
