Picea chihuahuana
Picea chihuahuana is a medium-sized evergreen conifer from the mountains of northwest Mexico, growing to 25 to 35 m tall, and it is rarely grown outside its native range. It needs cool, moist conditions, which suits it to mountain-valley streamsides rather than hot, dry sites.
Picea chihuahuana, the Chihuahua spruce, is a medium-sized evergreen tree growing to 25–35 m tall, and with a trunk diameter of up to 1 m. It is native to northwest Mexico, where it occurs in 25 small populations in the Sierra Madre Occidental mountains in Chihuahua and Durango. It grows at moderate altitudes from 2300 to 3200 m, growing along streamsides in mountain valleys, where moisture levels in the soil are greater than the otherwise low rainfall in the area would suggest.
The bark is thin and scaly, flaking off in small circular plates 5–10 cm across. The crown is conic, with widely spaced branches with drooping branchlets. The shoots are stout, pale buff-brown, glabrous, and with prominent pulvini. The leaves are needle-like, 17–23 mm long, stout, rhombic in cross-section, bright glaucous blue-green with conspicuous lines of stomata; the tip is viciously sharp.
