The Story
Plant Bio
Ornamental onions are bulbous perennials in the amaryllis family, prized for their showy, spherical flower heads and onion-like scent. They are highly resistant to deer and rabbits.
This compact variety produces dense, globe-shaped clusters of violet-purple flowers atop sturdy, leafless stems. Its foliage withers before the flowers appear, a common trait in many ornamental alliums.
