Euphorbia rigida (Upright Myrtle Spurge) is an erect, then spreading, evergreen perennial with upright ascending stems clad with fleshy, blue-green leaves arranged in close spirals. Through the spring months, it produces small clusters of star-shaped yellow-green flowers within a collar of chartreuse to bright yellow bracts, sometimes suffused with pink. The foliage sometimes tinges bronze or red in cold weather. The stems exude a milky sap that can be irritating so wear gloves when handling.
