(Euphorbia marschalliana marschalliana)
Euphorbia myrsinites, the myrtle spurge, blue spurge, or broad-leaved glaucous-spurge, is a succulent species of flowering plant in the spurge family Euphorbiaceae. The plant is native to southeastern Europe and Asia Minor, from Italy east through the Balkans to Crimea and Turkey. Myrtle spurge is an evergreen perennial. It has sprawling stems growing to 20–40 cm long. The leaves are spirally arranged, fleshy, pale glaucous bluish-green, 1–2 cm long. The flowers are inconspicuous, but surrounded by bright sulphur-yellow bracts (tinged red in the cultivar 'Washfield'); they are produced during the spring. Plants spread primarily by seed and are capable of projecting seed up to 15 feet. Euphorbia myrsinites is cultivated as an ornamental plant for its distinctive silver-gray foliage, and is used in garden borders, 'modernist' mass plantings, and as a potted plant. It is planted in drought tolerant gardens in California and other dry climates. In the United Kingdom, the cultivated plant has gained the Royal Horticultural Society's Award of Garden Merit.
