Allium cernuum Nodding Onion



Allium cernuum produces umbels of star-like flowers on leafless, upright stems. The loose clusters bend down, hence the common name of "Nodding Onion". Color is typically pink to lilac blue, occasionally white. Blooms in summer. The narrow, strap-like foliage smells of onion if bruised or cut, rendering it unattractive to deer and rabbits. May self-sow; remove old blooms if seedlings are undesired. This perennial will naturalize by bulb increase and via seed.

Allium cernuum is native to much of North America. It naturally occurs in prairies, on rocky outcrops and sunny edges of dry woodlands. Blooms are pollinated by short-tongued bees. It is a host for Hairstreak butterflies.

Allium cernuum is a bulbous perennial and prefers sun and moist to average, well-drained soil. It will tolerate light shade. It is drought tolerant once established.

    We ship via UPS or USPS (the Post Office), and their ship rates are automatically generated through our site. We do not profit on shipping costs. We are working with these providers to get our customers the best rates possible.

    All ship times are subject to change if extreme weather conditions are present here at the nursery or at the shipping destination.

    Please note: Depending on the time of year, the foliage of the plants may be trimmed to fit into our shipping boxes. This could delay the flowering of the plant, but many perennials actually benefit from being cut back.

    We are currently not able to ship to Puerto Rico, Hawaii, and outside of the US.
