Allium unifolium | One-leaf Onion
DESCRIPTION
Allium unifolium, commonly known as one-leaf onion, produces delicate, star-shaped flowers in soft shades of pink to lavender. These blooms form loose clusters that appear in late spring to early summer, creating a charming display in garden beds and borders. The plant's name refers to its unique growth habit, where each bulb typically produces a single strap-like leaf alongside the flower stem.
Native to western North America, particularly California and Oregon, Allium unifolium thrives in a variety of habitats, including grasslands and open woodlands. Its adaptability and ornamental appeal make it a popular choice for naturalized gardens, rockeries, and pollinator-friendly landscapes. This species also performs well as a cut flower, adding a graceful touch to floral arrangements.
