Favorite or New Plant

Blue Euphorbia
Amongst a desert palette of unusual-looking plants, blue euphorbia (Euphorbia rigida) still stands out as eccentric. Blue foliage and chartreuse flower bracts combine to produce a cool, but nevertheless vibrant, splash of color. Blooms appear in mid-winter to early spring. This species is hardy to 15 degrees F., is drought tolerant, and takes full sun or partial shade. It spreads fairly slowly in low-growing mounds, reaching about 2 feet high and 3 feet wide. No thorns, but it exudes a milky sap that is irritating to skin.
