Allium 'Medusa' Ornamental Onion



Allium 'Medusa' has narrow grass-like leaves that twist around taller stems supporting light purple, nearly 2" spherical clusters of flowers in late summer. The snaky foliage produces a typical onion scent when cut or bruised. As with the other Allium, 'Medusa' is a magnet for butterflies and honeybees.

Allium 'Medusa' prefers full sun to light shade and well-drained soil. This is a drought tolerant, deer-resistant, easy to grow, bulbous perennial. For a winning combination, pair this cool-colored perennial with yellows and golds in the landscape.

    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.
