Allium, ornamental onion, produces striking globe-shaped flower clusters atop tall, leafless stems, adding architectural drama to a garden bed unlike almost any other bulb.
This large genus includes edible relatives like onion, garlic, and chives, but the ornamental varieties are grown purely for their striking spherical blooms, which range from softball to volleyball size. Deer and rodents generally avoid Allium thanks to its mild onion scent, making it a reliably pest-resistant bulb choice.
Allium symbolizes unity and prosperity, its perfectly spherical bloom often read as a symbol of good fortune and patience, since the flower takes its time to slowly open into its full round shape.
Plant Allium bulbs in fall for spring and early summer blooms, choosing a full-sun spot with well-draining soil, since bulbs are prone to rot in consistently wet ground. Once established, Allium is remarkably low-maintenance and drought-tolerant, and the dried seed heads left after flowering make an attractive addition to the garden or dried arrangements.
Edible Allium relatives — garlic, onion, and chives — have a long history of use in traditional medicine for their antimicrobial and cardiovascular benefits, though ornamental Allium varieties are grown strictly as garden flowers rather than for consumption.
