Brewer Spruce
Picea breweriana
Pinaceae · conifer · native
You likely encounter this tree in a sheltered location where its distinctive weeping branches develop fully. Brewer spruce's pendulous branchlets form curtains of foliage that hang like green drapery, a habit that emerges as the tree matures over decades. Yet young trees deceive; they begin life with an open crown before revealing this dramatic weeping architecture that makes them unmistakable in cultivation.
In the Pacific Northwest, this tree thrives in well-drained soils with reliable moisture and moderate shade, though it grows slowly (roughly 25 feet in 20 years). Plant it where its eventual 50-80 foot height and pendulous form can command attention without crowding other plants. Watch for needle cast diseases and root rot in wet sites; good drainage is your best insurance. Spruce aphids and spider mites can disfigure foliage in hot, dry years.
