description_en: Genus of 50-60 species of evergreen, coniferous shrubs and tall trees from dry forests and hillsides throughout the N. hemisphere. Juvenile leaves are usually needle-like or narrowly wedge-shaped, and 0.5-1.5cm (1/4-1/2in) long. Adult leaves are usually scale-like and overlapping, either lying flat along the shoots or spreading, and 2-6mm (1/16-1/4in) long. In most cases, male and female cones are borne on separate plants: male cones are spherical to ovoid, yellow, and to 5mm (1/4in) across; females develop into usually spherical, fleshy, berry-like fruits, 4-10mm (1/8-1/2in) across, with 1-10 seeds, and are persistent, generally ripening over 2 to 3 years. Junipers tolerate a wide range of soils and conditions, and are useful for hot, sunny sites. Use as specimen plants; the smallest species in a rock garden and the prostrate species as ground cover. Contact with the foliage may aggravate skin allergies.
