Allium 'Medusa's Hair'

This ornamental onion has snaky, twisty leaves like the legend of Medusa's hair, with nodding flower buds that look like snakes heads, before they straighten to form large round clusters of light amethyst-purple flowers. Hardy and easy to grow. Perfect for patio containers. Butterflies and bees adore the long lasting flowers. This plant dies down in winter to regrow in spring.

Plant Care

Keep well watered until firmly established. Plant into any average garden soil, avoiding wet areas. Feed with a good liquid fertiliser every two weeks in the flowering season.

Planting Instructions

Water thoroughly, or stand pot in a container of water for half an hour before planting. Dig a hole twice the size of the root ball. Remove the pot, place the plant in the hole so that the root ball is level with the surrounding ground and refill, firming if necessary. Keep well watered in dry weather. Feed in spring with a good, general fertiliser.
