Allium senescens ssp. glaucum (Corkscrew Allium)
The common name "corkscrew" for this species refers to its due to its unique swirling foliage. Most Alliums are generally grown for the flowers; this one is also prized for its striking blue-green foliage and extended season interest.
Corkscrew Allium grows in dense clumps about 10 in. high and 6-10 in. wide, with linear, flat and twisted gray to blue-green leaves that provide long-lasting interest in the garden. Blooming late summer into fall, the butterfly- and bee-attracting flowers are pink to lavender, cup-shaped, and open from nodding buds into 1-2 in. wide balls held high above the foliage on wiry stems.
Corkscrew Allium is more part-shade tolerant than other Alliums, and also handles a wide range of soils from fairly heavy clay to sandy loam. It is drought tolerant once established and deer resistant due to the pungent onion taste.
Deadhead to prevent seedlings that may not retain true characteristics. Propagation is by division of the clumps in early spring or fall.
