Discovered as a seedling of Euphorbia characias in a garden in Tasmania, this phenomenal spurge has both variegated leaves and flowers, combining blue-green with creamy white. Upright stems are a forest of linear leaves, forming a dense shrubby mound. In spring through early summer, large heads of flowers hover on 2- to 3-foot stems, pale yellow and cream, with small green bow-tie centers. Evergreen where winters are mild. Zones 6-9.
