Overview
Hesperocyparis arizonica, the Arizona cypress, is a species of conifer in the cypress family, Cupressaceae, native to the southwestern United States and Mexico.
This selection is valued for its unique mature habit and ornamental traits. In our Raleigh climate, it performs best when given enough space to reach its natural size without aggressive pruning.

Foliage & season
Growing & care
Practical notes for establishment and seasonal care in the Triangle—adjust for local soil tests and microclimate.
Light
Full sun is generally required to maintain a dense habit and the best needle color in our region.
Watering Procedure
Water at the base until the root zone is saturated (usually 45-60 seconds for new plants). Check the top inch of soil; if dry, it's time to water again.
Planting & Soil
In our heavy Raleigh clay, this is a great performer if you prep the soil well. Dig your hole twice as wide as the root ball but no deeper. Mix 30% compost with your native clay backfill to open up the soil—this helps the roots breathe and prevents water from pooling. Planting 'slightly high' also ensures the roots stay healthy.
Fertilization
Fertilize sparingly if at all. A light spring application is usually enough; over-fertilizing evergreens in our humidity can lead to weak, leggy growth.
Pruning / upkeep
Prune lightly to maintain structural shape; avoid cutting into old, leafless wood on needle evergreens like Junipers or Cedars.
Common questions
Is Arizona Cypress 'Quick Frost' a good plant for Raleigh and the Triangle?
Yes—when the site matches its light and drainage needs. Arizona Cypress 'Quick Frost' is used in Raleigh, Durham, and Cary landscapes in USDA zones 7b–8a. Confirm mature width, overhead wires, and how wet the Piedmont clay stays after storms before you plant.
When should I plant Arizona Cypress 'Quick Frost' in North Carolina?
Fall (October–November) is the safest window for Arizona Cypress 'Quick Frost' in the Piedmont: soil is still warm, air is cooler, and roots can grow before summer. Spring after the last frost works if you can water deeply through the first hot season.
Will Arizona Cypress 'Quick Frost' grow in Piedmont clay?
It can, with careful planting: wide hole, crown slightly above grade, and no water sitting on the root flare. Heavy, poorly drained clay is the usual failure mode—not summer heat alone.
Does Arizona Cypress 'Quick Frost' lose its leaves in winter?
No. Arizona Cypress 'Quick Frost' is evergreen and keeps foliage year-round, which is why it is used for winter structure and screening in Triangle yards.
