Alligator juniper

The bark is usually very distinctive, unlike other junipers, hard, dark gray-brown, cracked into small square plates superficially resembling Alligator skin; it is however sometimes like other junipers, with stringy vertical fissuring. The shoots are 1-1.5 mm diameter; the leaves are arranged in opposite decussate pairs or whorls of three; the adult leaves are scale-like, 1-2.5 mm long and 1-1.5 mm broad. The juvenile leaves are needle-like, 5-10 mm long. The cones are berry-like, 7-15 mm in diameter, green maturing orange-brown with a whitish waxy bloom, and contain 2-6 seeds; they are mature in about 18 months. The male cones are 4-6 mm long, and shed their pollen in spring. It is largely dioecious, producing cones of only one sex on each tree, but occasional trees are monoecious.

Juniperus deppeana is native to North America. Range may be expanded by planting. See states reporting alligator juniper (opens a new window). More
