Picea breweriana (Pinaceae) is a rare evergreen conifer endemic to the Siskiyou Mountains of southwestern Oregon and northwestern California. It grows 50 to 80 feet tall, forming a narrow pyramidal crown with the most dramatically weeping branches of any spruce: secondary branches hang vertically up to 2.5 meters like curtains from the horizontal main limbs.
Brewer spruce is considered one of the most beautiful native conifers. It requires a cool, moist climate and grows slowly. In the wild it is restricted to high elevations on serpentine and other nutrient-poor soils. It is rarely offered in the nursery trade. Hardy in Zones 6a to 8b.
