Description: Arizona Cypress is a silvery blue/teal, conical-to-pyramidal-shaped conifer. It is a fast-growing tree, reaching 40′-60′ tall and 15′-20′ spread at maturity. Its gray-brown bark is rough and shedding. Its closely overlapping scale-like needles encircle the branchlets. They are soft, aromatic, and gray-green. Its dark reddish-brown cones are 1”–1 1/4″ in diameter. Arizona Cypress is heat and drought-tolerant. It’s also a strong choice for windbreaks, erosion control, Christmas trees, and ornamental landscapes.
