The Jezo Spruce (Picea jezoensis) is a large evergreen tree growing to 30-50 m tall and with a trunk diameter of up to 2 m. It is native to northeast Asia, from the mountains of central Japan and the Changbai Mountains on the China-North Korea border, north to eastern Siberia, including the Kuril Islands, Sakhalin and Kamchatka. It is found in cold but humid temperate rain forests, and nowhere does its range extend more than 400 km from the Pacific Ocean. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

• Picea jezoensis subsp. jezoensis (Jezo Spruce). All of the range except as below, south to Hokkaido, Japan. Shoots very pale buff-brown, almost white; stomatal bands blue-white; cones pale brown with flexible scales.
• Picea jezoensis subsp. hondoensis (Mayr) P. A. Schmidt (Hondo Spruce). An isolated southern population on high mountains in central Honshu, Japan. Shoots buff-brown to orange-brown, less often very pale; stomatal bands bright white; cones orange-brown with stiffer scales.

Jezo Spruce is very closely related to Sitka Spruce (Picea sitchensis), which replaces it on the the opposite side of the north Pacific. They, particularly subsp. jezoensis, can be difficult to distinguish, with the absence of stomata on the upper surface of the leaves of P. jezoensis being the best feature. Its leaves are also somewhat blunter, less sharply spine-tipped, than Sitka Spruce.
