Euphorbia 'Excalibur'

Euphorbia ‘Excalibur’ is a vigorous, clump-forming herbaceous spurge grown for its striking variegated foliage and vivid early-summer display. Upright stems carry lance-shaped leaves with creamy margins, offset by showy orange bracts in early to midsummer. Best in sun or light shade and moisture-retentive, fertile but well-drained soil, it forms bold clumps around 60–90cm tall, adding strong colour and structure to mixed borders in Irish gardens; cut back spent stems after flowering and handle with care due to the milky sap.

To help give a clear sense of scale, the stone wall shown in our photos measures approximately 265cm in height. We also use familiar garden tools as visual references: a digging fork (110cm tall) and a hand fork (30cm tall). These are included purely as size guides to help you better judge proportions when viewing the images.
