Common names: myrtle spurge, creeping spurge
Euphorbia myrsinites L. (myrtle spurge) is an evergreen perennial that is native to Eurasia and has been widely introduced as an ornamental. Plants typically grow to 4-8″ tall from a woody base. Stems are ascending or trailing. Oval, blue-green, fleshy leaves are arranged in close spirals around stems. Plants bloom in spring; flowers are inconspicuous and greenish, subtended by showy yellow bracts. Myrtle spurge is listed as noxious weed in Colorado, Oregon, Washington and Utah, as well as California. Its leaves contain a latex that is a skin irritant and toxic to animals. This species can spread aggressively and is difficult to control once established.
