Allium Medusa (Ornamental Allium)

Aptly named, Allium ‘Medusa’ (Ornamental Allium) is a bulbous perennial boasting profuse, 2-inch rounded clusters (5 cm), packed with amethyst-purple flowers. Blooming from late summer to early fall, they open from nodding buds that look like snakes at the tips of the stems, just like Medusa hair. Borne on sturdy stems, the blossoms seem to float above the low foliage mound of twisting and curling, gray-green leaves.
