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 selected form of nodding onion with taller stems, larger flowers, and a deeper pink colouring than the species. The umbels nod in bud before lifting slightly as the bells open in early summer. Flower stems show a purplish blush, adding a subtle depth to the plant’s overall appearance. Clumps are neat and compact, well suited to open borders, gravel gardens, or naturalistic settings. As with the species, plants favour full sun and well drained soil and broaden slowly over time. Dried heads remain tidy into early autumn.
