Two major spruces are found in the western forests of the United States. Engelmann spruce (Picea engelmannii) is found throughout the Rocky Mountains, from Alberta to Arizona. It’s named after George Englemann, who discovered this species in the mid-1800s. Sitka spruce (Picea sitchensis) is found primarily within 50 miles of the Pacific Coast, from Alaska to northern California. The name comes from Sitka Island, where the tree was discovered in 1892; Sitka spruce is also Alaska’s state tree.
