Cypress Tree

Cupressus is the genus of true cypresses, a group of evergreen conifers in the Cupressaceae family. Species range from narrow, upright trees to broader or irregular forms, with small scale-like leaves and rounded cones. ## Choosing a cypress The name covers many species from warm-temperate regions of the Northern Hemisphere, and their mature size, hardiness, and preferred conditions differ substantially. Select a species or named cultivar before planning spacing or climate suitability; genus-level measurements do not predict the mature size of any particular tree. Several species have aromatic foliage, but scent, color, and growth habit vary. ## Site planning Many cultivated cypresses are used as specimens, screens, or windbreaks, but the appropriate use depends on the exact species and its mature form. Check the species-level requirements for sun, soil drainage, water, and cold tolerance before planting. Avoid assuming that drought tolerance or a narrow crown applies to every true cypress.

Keep young trees watered as roots establish, maintain clear spacing for the expected crown, and remove dead or damaged growth with clean tools. The 2025 Yavapai County guide lists Cupressus at genus scope among fire-prone plants. This is a fire-hazard warning, not an individual assessment of every species or cultivar. Follow the guide's placement and maintenance guidance. ## Yavapai County — 2025 source scope and care The [University of Arizona Yavapai County bulletin](https://extension.arizona.edu/sites/default/files/2025-03/FirewisePlants3-14-2025.pdf), page 3, lists Cypress with the botanical cell Cupressus sp. and form T. It places this entry in its fire-prone list. The matched catalog name is Cupressus. Source form codes: C=groundcover, G=grass, P=perennial, S=shrub, T=tree and V=vine. Printed names and form codes can include source spelling errors or historical taxonomic treatments; the source wording is retained separately from the catalog name and plant-specific habit. The bulletin warns that fire-prone plants can ignite readily and burn intensely, and should be removed or aggressively maintained when near a home, road or driveway. For native trees it calls for removing dead material, keeping limbs out of the lower 6–10 feet and clearing shrubs beneath the canopy. For other fire-prone natives it calls for isolated stands more than 30 feet from structures. Apply current local requirements and pruning suited to the identified plant. No plant is fireproof. Keep this Yavapai classification separate from Arizona UA, Utah, New Mexico, Idaho, Colorado and other source ratings and their placement, moisture and maintenance conditions.
