Botanical Name

Plant Common Name

Alberta Spruce

General Description

A variety of white spruce, this large evergreen conifer is native to Southwest Canada, Montana, and Wyoming. It is best known for its slow-growing cultivar 'Conica', commonly known as dwarf Alberta spruce.

Broadly pyramidal when young, Alberta spruce becomes more columnar with age. Its cones are relatively small. Crushed needles emit a pungent, skunky smell. Many cultivars of white spruce are available, including the compact, pyramidal 'Conica'.

White spruce grows best in sun and moist, well-drained soil, and tolerates drought, salt, extreme cold, and other environmental stresses. Excessively dry, cold winter winds can eventually kill foliage. It is useful for screening, hedges, windbreaks, and as a specimen. It is also sometimes used as a Christmas tree, although the needles do not persist long once the cut tree dries.
