- Description
-
The Arizona Cypress is a conical needled evergreen tree native to Arizona in the southwestern United States and often found in the rocky or gravelly soils of canyons and ravines. The tree cab mature to a height of 70 feet, although most are much shorter, and is noted for its hardiness, thriving in any soil from chalk to acidic sand. The tree will produce inconspicuous brown blossoms and seed cones that mature to gray or brown a few years after pollination. A mature tree will often have multiple trunks with smooth, dark red bark peeling in large scales.
The Arizona Cypress tolerates a wide range of soils and it drought resistant. However, it will not grow in shade and does best sited in full sun.

No known diseases or insect pests. Resistant to cypress canker.
