Euphorbia characias 'Silver Swan' pbr

Common Name:
Silver Swan Spurge

Description:
Euphorbia characias 'Silver Swan' PBR is a striking, evergreen perennial known for its architectural form and beautifully variegated foliage. This compact cultivar features slender grey-green leaves edged in silvery-white, forming a neat, dome-shaped shrub that brings a luminous quality to garden beds and borders year-round. In late winter to spring, it produces tall stems topped with clusters of lime-green flowers with white bracts, providing striking contrast against the foliage. Bred for its ornamental value and improved uniformity, 'Silver Swan' thrives in Melbourne’s dry summers and mild winters, preferring full sun and free-draining soil. It's ideal for modern gardens, Mediterranean landscapes, gravel gardens, and low-water planting schemes. Like many euphorbias, it’s drought-tolerant, deer-resistant, and low-maintenance, though care should be taken when pruning as the milky sap can cause skin irritation.
