Distribution en:
Description en: Genus of 30-40 species of monoecious, evergreen, coniferous trees occurring in forest in cool-temperate regions of the N. hemisphere. They have whorled branches and needle-like leaves set singly around the shoots. The woody, oval to oblong-cylindrical female cones, terminal on main shoots and sideshoots, are erect at flowering, later pendent; they ripen in a season from green or red when young, to purple or brown when mature. Ovoid, yellow to red-purple male cones, 2-3cm (3/4-1 1/4in) long, are borne in spring on the previous year’s shoots. Spruces are useful for shelter planting or as specimen trees; several cultivars are dwarf or slow-growing.
Hardiness en: Fully hardy to frost hardy.
