==Description==
[[File:Picea schrenkiana Rogów 2.JPG|thumb|left|''Picea schrenkiana'' tree in Rogów Arboretum, Poland]]
''Picea schrenkiana'' is a large [[evergreen]] [[tree]] growing to {{convert|40|-|50|m|ft}} tall (rarely to {{convert|60|m|ft}}), with a trunk diameter of up to {{convert|1|-|2|m|ft}}. It has a narrow conical crown with level branches and sometimes pendulous branchlets. The shoots are pale buff-brown, and glabrous (hairless). The [[leaf|leaves]] are needle-like, 1.5-3.5 cm long, rhombic in cross-section, dark green with inconspicuous [[stoma]]tal lines.

The [[conifer cone|cones]] are cylindric–conic, 6–12 cm long and 2 cm broad, purple when young, maturing dark brown and opening to 2.5–3.5 cm broad 5–7 months after pollination; the scales are moderately stiff and smoothly rounded.

===Subspecies===
There are two [[subspecies]]:
*''Picea schrenkiana'' subsp. ''schrenkiana''. Eastern Tian Shan, in Kazakhstan and Xinjiang. Leaves longer, 2–3.5 cm long.
*''Picea schrenkiana'' subsp. ''tianshanica'' (Rupr.) Bykov. Western Tian Shan, in Kyrgyzstan. Leaves shorter, 1.5–2.5 cm long.

It is closely related to, and in many respects intermediate between Morinda spruce (''[[Picea smithiana]]'') from further south in the [[Himalaya]], and Siberian spruce (''[[Picea obovata]]'') further north in [[Siberia]].

==Uses==
Schrenk's spruce is an important tree in central Asia for [[timber]] and [[paper]] production, where few other large trees exist. Its slower growth compared to [[Norway Spruce]] reduces its importance outside of its native range.

==Cultivation==
''Picea schrenkiana'' is grown as an [[ornamental tree]] in large [[garden]]s and public parks in [[Europe]].
