Euphorbia 'Ascot Rainbow' is a semi-evergreen perennial that can take full sun to part shade, lots of heat and humidity. This photo is a close-up of the bracts (flowers). Other Euphorbias (Spurge) have burgundy, blue-green or chartreuse foliage, a plant with multiple seasons of interest. One note, wear gloves when cutting Euphorbias, as they release a white, milky sap that can irritate skin. Ruth Consoli Design
