Forming attractive colonies, Allium unifolium adds a delicate beauty to borders and containers - excellent cut for your indoor arrangements too. Long-lasting clusters of 20-30 pink-mauve, shaggy, bell-shaped flowerheads with petals that feel almost papery to the touch. Strappy foliage appears in spring and has usually become dormant by the time the flowers appear in May, June, and July.Native to the coastal mountains of California, it is known by the common name, Oneleaf Onion, the reason for this is unclear as it usually has 2-3 flat leaves which reach around 50cm in length.Given the Award of Garden Merit by the RHS for outstanding performance in the garden, Allium unifolium entices bees and other pollinators in for a nectar filled feast but tends to be ignored by deer and rabbits.Drought tolerant, plant in a sunny position in well-drained soil, where it will reach a mature height of 30-60cm, spreading 10-25cm. Hardy to -15 C, Allium unifolium becomes dormant over winter, before sprouting again in the spring.
