General: Cypress Family (Cupressaceae). Red cedar (Juniperus virginiana) is a medium-sized dioecious or rarely monoecious tree from 10-20 m (33-66') tall (McGregor et al. 1986, Stephens 1973). The evergreen tree is shaped like a pyramid or column, with reddish-brown to grayish colored bark that is fibrous and shedding. Branches are usually reddish-brown. Leave are opposite, simple, green or blue-green, closely appressed and overlapping the leaf above, scale-like, and 0.2-0.3 cm (1/16-1/8”) long or needlelike and 0.6-1.2 cm (1/4-1/2”) long. Male and female cones are on separate trees. The staminate (male) cones are yellowish-brown, papery, solitary at the tips of branchlets, ovoid to ellipsoid, and 0.2-0.4 cm (1/16-1/8”) long. The ovulate (female) cones are solitary at the tips of branchlets, dark blue or bluish-purple, waxy and berrylike, 0.4-0.7 cm (3/16-1/4”) long. The female cones ripen from September through October. There are 1-3 seeds per cone. Red cedar seeds are yellow-brown and round, 2-4 mm in diameter, ridged near the base, and sometimes shallowly pitted.
