(Flowering Onion, Persian Onion)

Although this Central Asian native is rare in cultivation, many "drumstick alliums" - including the popular cultivar 'Purple Sensation' - are incorrectly sold under this name. Most bear large spherical heads of lilac-purple flowers on tall stems in late spring. The strap-shaped basal leaves wither shortly after the flowers appear.

These plants like rich, well drained soil and full sun. Use them as bedding plants or in mixed borders. They attract butterflies, and are relatively unpalatable to...
