Myrtle spurge

Myrtle spurge is a low, evergreen perennial with trailing stems wrapped in spirals of fleshy, blue-green leaves. In spring, small flowers sit within bright yellow bracts, making the plant conspicuous in rock gardens and dry sites. ## Landscape Use Its spreading form has been used as a ground cover, in containers, and on rock walls. Before planting or moving it, check local rules: extension guidance identifies it as a noxious weed in several western states, and Utah State University reports that it spreads by seed and root in foothill habitats. ## Growing Conditions Choose full sun and dry, sharply drained soil; it tolerates poor, rocky, and sandy ground. The species is evergreen, though cold and wind can damage foliage. North Carolina Extension lists a mature height of 4–6 inches and width of 6 inches to 2 feet, and notes that seeds can be projected well beyond the parent plant. ## Maintenance Remove spent flower heads before seed matures where its cultivation is permitted, and wear gloves when handling it. The milky sap can irritate skin and eyes and is poisonous if swallowed.
