Juniperus scopulorum is a small evergreen tree that in favorable conditions may reach as much as 20 metres (66 feet) in height. [4] However, on sites with little water or intense sun it will only attain shrub height, and even those that reach tree size will more typically be 4.6–6.1 metres (15–20 feet) tall in open juniper woodlands.

Juniperus virginiana foliage and mature cones. Juniperus virginiana is a dense slow-growing coniferous evergreen tree with a conical or subcylindrical shaped crown [8] that may never become more than a bush on poor soil, but is ordinarily from 5–20 metres (16–66 feet) tall, with a short trunk 30–100 centimetres (12–39 inches) in diameter, rarely to 27 m (89 ft) in height and 170 cm (67 ...

The cones are berrylike, 7 to 13 mm (1 ⁄ 4 to 1 ⁄ 2 in) in diameter, blue-brown with a whitish waxy bloom, turning reddish-brown, and contain a single seed (rarely two or three). [5] The seeds are mature in about 8 or 9 months. The male cones are 2 to 4 mm (1 ⁄ 16 to 3 ⁄ 16 in) long and shed their pollen in early spring.
“Leaves can turn brown if you freeze your plant,” says Borisevich. Avoid this by making sure your plant’s foliage isn’t touching cold window glass. Move any pots on the floor to an ...
A resistant juniper tree surrounded by junipers infected with Phomopsis juniperova. Planting only resistant varieties of juniper is the most efficient method of preventing Phomopsis blight. [10] For information on resistant cultivars contact a local extension office. If blight is already established in a population, then the most effective ...
The seed cones are the largest of any juniper, berry-like but hard and dry, green ripening in about 25 months to dark purple-brown with a pale blue waxy coating; they are ovoid to spherical, 20–27 mm (3 ⁄ 4 –1 in) long and 20–25 mm diameter, and have six or nine fused scales in 2–3 whorls, each scale with a slightly raised apex.
