Allium cernuum f. albiflorum
A white-flowering form of the nodding onion, native to parts of British Columbia. The flower heads arch before opening, then lift slightly as the white bells expand in early to midsummer. Stems are slender and upright, carrying the flowers above narrow, grass-like foliage. Plants prefer full sun and freely draining soil, forming small clumps that broaden slowly. Occasional self-seeding may occur in open ground but remains modest. The dried heads stay neat into early autumn.
