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 female cone (megastrobilus, seed cone, or ovulate cone) contains ovules which when fertilized by pollen become seeds. The female cone structure varies more markedly between the different conifer families and is often crucial for the identification of many species of conifers.
The male pollen cones may be axillary or terminal and solitary or grouped. They have glabrous peduncles. A pollen cone consists of many spirally arranged microsporophylls each with two pollen sacs producing bisaccate pollen. [1] The female seed cones develop from axillary buds. They are often solitary but may also be paired.

The cones are globose to oval, 1–3 cm diameter, with 15-35 scales, each scale with 3-6 seeds; they are mature in 7–9 months after pollination, when they open to release the seeds. The male (pollen) cones are small, and shed their pollen in early spring.
