Description from Digging Dog Nursery
Named after Euphorbus, physician to the king of Mauritania, this robust, sun-loving genus includes the familiar Poinsettia and is over 1600 species strong. Most species have a poisonous milky sap and softly colored bracts that surround subtly defined flowers. Autumn watches their narrow green leaves turn shades of red, orange and yellow.
Distinctive and drought tolerant, this Euphorbia deserves to be used as a specimen. Its cylindrical flower heads are yellow-green and can reach 6 to 9 in. across and 9 in. high. Combine with an understory of Nepeta and Heuchera “Apple Blossom’, and enjoy the dynamic array of bloom color.
Size: 3’5′ high x 3’4′ wide; hardy to zone 7.
