White Nodding Onion

ALLIUM (Liliaceae) ornamental onion

Allium offer clean vertical accents in the border, with rounded or domed flower heads held above the foliage. They are straightforward to grow in full sun and freely draining soil, and their simple, architectural shapes work easily with a wide range of perennials and grasses. As the flowers fade, many species leave dry seed heads that persist well into autumn, carrying the season quietly forward. The mild onion scent in the foliage helps deter browsing wildlife, adding to their reliability in both designed and naturalistic plantings.

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.
