P. breweriana is endemic to the Western United States. You can only find them in the Klamath Mountains in Southern Oregon and in the Siskiyou Mountains in North California. In these regions, the Brewer Spruce climbs to nearly 6561.7 feet (or 2000 metres). I found this one however in the botanical garden of Solingen, West Germany.
