Allium senescens ssp. glaucum

1/3

German Garlic

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 compact subspecies with blue-glaucous leaves that curve and twist, forming low, tidy clumps from early spring onward. Rounded heads of dark lilac flowers appear in late summer, rising just above the foliage. The plant maintains its presence from spring through autumn and is particularly effective in the foreground of sunny plantings. Clumps broaden steadily and may self-seed lightly in favourable conditions. Prefers full sun and well drained soil, showing good durability in heat and lean sites.
