Allium carinatum ssp. pulchellum

Keeled 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 small, fine-textured Allium with loose, nodding flower heads that read as soft, open spheres above narrow foliage. The flowers are a clear pink and bring a light, lifted note to midsummer plantings. It works especially well threaded through low grasses where its movement and spacing feel natural. Best in full sun and sandy, freely draining soil, and equally at home in borders or rock gardens. Clumps expand slowly and the plant self-seeds in a gentle, unobtrusive way, adding to its scattered, meadow-like effect.
