Alligator juniper (Juniperus deppeana), also known as checkerbark juniper, is a distinctive native species found in Arizona’s mid- to high-elevation woodlands, typically between 4,000–8,000 feet. This small to medium-sized tree usually reaches 30–50 feet in height, though some specimens can grow taller. Its most recognizable feature is the bark, which forms hard, dark, square plates that resemble alligator skin—an easy field marker that sets it apart from other junipers in the region. The foliage transitions from juvenile needle-like leaves to adult scale-like leaves, typically dull gray-green to glaucous blue depending on variety. Alligator juniper is largely dioecious, producing separate male and female cones; the berrylike seed cones mature over about 18 months and are an important food source for birds and mammals. Arborists should note that while the tree is highly drought tolerant and adapted to dry, rocky soils, it often develops multiple stems or split trunks, which may require structural pruning considerations in managed landscapes. |

Why Are There So Many Palm Trees in Phoenix?
KJZZ Phoenix
When you think of the landscape of Phoenix, you might think first of cactuses, mountains — and probably palm trees. KJZZ's Q&AZ project asked: Why are there so many palms trees in Phoenix when they don't provide any shade? The story begins almost 150 years ago. |
