About Allium schubertii (Ornamental Onion)

Allium schubertii - Commonly called tumbleweed onion, is a bulbous perennial that is ornamentally grown for its impressive display of rose-purple flowers that bloom in giant, spherical umbels in late spring.  It typically grows to a modest 12-24" tall. Strap-shaped, blue-green, basal leaves form a clump of foliage in spring surrounding a stout scape rising to 1' tall. Leaves begin to wither as the flowers begin to bloom. Flowerheads are unique and attractive. Small flowerhead are rose-purple, star-like flowers. Seed heads dry after bloom, and can be left on the plant for ornamental reasons or picked for flower arrangements. Leaves and bulbs have an oniony aroma when cut or bruised. Family : Liliaceae
