Ornamental Onion

Pink Lily Leek is a small plant with genuine presence — ten to twelve inches of flat linear leaves, then a loose umbel of rosy-red bell-shaped flowers in May that seem, briefly, to be exactly the right thing in exactly the right place.

Native to the mountains of Eurasia, Allium oreophilum is the kind of alpine plant that translates beautifully into the garden without losing its essential character. It blooms for two to three weeks in May and June, producing loose umbels of ten to fifteen rosy-red flowers on stems eight to twelve inches tall — modest in scale but vivid in color, particularly when planted in the mass groupings it thrives in. The flat, linear leaves remain attractive through midsummer before dying back, leaving the ground clear for summer perennials to take over.

This is a plant that spreads slowly and with purpose, naturalizing gradually to form a colony without becoming a nuisance. Plant bulbs in autumn, four to five inches deep and two to three inches apart, in well-drained soil in full sun or partial shade. It is drought tolerant once established and earns its Royal Horticultural Society Award of Garden Merit particularly in rock and alpine garden settings where its compact habit and jewel-like flowers can be appreciated at close range. A note of interest: the flowers are considered mildly toxic, though they have historically been eaten in small quantities — handle with the same casual respect you might give any Allium.
