Euphorbia characias 'Silver Swan'

Euphorbia characias 'Silver Swan' is a highly architectural and drought-tolerant perennial, prized for its stunning variegated foliage and long-lasting, lime-green flowerheads with white margins. Its upright, bushy habit forms a striking mound of glaucous, grey-green leaves edged with creamy white, providing year-round interest in UK gardens. The vibrant bracts appear from late winter through spring, lasting for many months. This cultivar is particularly effective in Mediterranean-style plantings, gravel gardens, or as a focal point in borders. It requires full sun and very well-drained soil to thrive, tolerating poor soils and coastal conditions. Handle with care as the sap can be an irritant.
