Cupressus arizonica var. arizonica
A moderately large cypress to over 25 m (80 ft.) tall, native to western Texas, New Mexico and southeastern Arizona between 900 to 1500 m (3000 to 4900 ft.) and northeastern Mexico to 2700 m (8900 ft.), where it grows on dry slopes and in canyons. The scale-like leaves on much-branched shoots have a silvery-blue hue. While young trees have a conical shape, old plants develop a dense, broad, spreading crown. Hardy to drought and severe freezes, it is best suited to dry temperate climates in USDA hardiness zones 7 to 9. Seeds require cold stratification for a month after sowing.
