Allium Hair

Ornamental Onion ‘Hair’ (Allium ‘Hair’) immediately draws attention with its green flower heads extended by twisted purple tips, creating the appearance of tousled hair. Its unusual flowers appear from June to July on stems reaching 50 to 60 cm in height, adding texture, movement, and whimsy to garden displays. Its blue-green foliage elegantly complements this distinctive silhouette, which is especially striking in modern or naturalistic gardens. Hardy to Zone 4, this perennial bulb provides a lasting graphic effect and stands apart from alliums with more traditional spherical flower clusters.

Plant the bulbs in fall at a depth of 10 to 15 cm, spacing them 15 to 20 cm apart. ‘Hair’ prefers full sun and light, rich, perfectly drained soil with a neutral to slightly alkaline pH. Water lightly after planting, then moderately during active growth, allowing the soil to dry between waterings. Once well established, this allium tolerates dry periods. A light application of compost in spring is generally sufficient. After flowering, allow the foliage to turn completely yellow before cutting it back so the bulb can replenish its reserves.

This unusual allium is ideal for contemporary flower beds, borders, rock gardens, naturalistic gardens, and graphic-style plantings. It pairs especially well with ornamental grasses, sage, catmint, lavender, and coneflowers, which highlight its original form. Its nectar-rich flowers attract bees, butterflies, and many other beneficial insects, helping support garden biodiversity. The flower heads can also be used in fresh or dried bouquets, while those left standing in the garden remain decorative for several months.
