USDA Symbol: HEAR22
Arizona cypress is a graceful, pyramid-shaped tree, 30-40 ft. high (usually taller in the wild) by 15-20 ft. wide. Evergreen tree with conical crown and stout, horizontal branches. Soft-textured, pale, gray-green to blue-green, evergreen foliage is scale-like and flattened against the branchlets; the overall effect is like a braided bullwhip. The rough outer bark of older trees scales off to reveal an inner bark that changes color from tan to plum to red.
Arizona Cypress is often grown for Christmas trees. The durable wood is used locally for fenceposts. As many as 5 varieties, based on minor differences of foliage and bark, have been distinguished.
