This ornamental onion has snaky, twisty leaves that will remind you of the snake hair from the Medusa legend. ‘Medusa’ forms a low mound of grey-green, narrow foliage with leaves the twist slightly at the end. The nodding buds look like snakes at the tips of the stems, before they straighten to form 1¾-2” rounded clusters of light amethyst purple flowers. Similar in flower color and flower foliage to ‘Blue Eddy’, but in a much larger form.
Alliums are charming plants for the rock or herb garden. When the foliage is bruised, it smells like onions since they are in the onion family. Butterflies and honeybees adore the flowers' sweet nectar but deer and rabbits steer clear of this perennial beauty.
