Picea pungens. COLORADO SPRUCE. Wyoming, Utah, Colorado, New Mexico
PINACEAE (Pine family)
ore common in cold climates but Colorado spruce can be
found in the Bay Area, often installed by transplanted gardeners who grew up with
them or those who are setting out live Christmas trees. The short needles of Picea
pungens are sharply pointed, ranging in color from green to gray green to blue
green; the toothed cones are slightly more than an inch in diameter, cylindrical,
around 3 inches long. Examples are in Serra Grove between Sequoia Hall and Serra
Mall, and at 1012 Vernier Place. Most campus specimens appear to be the blue-gray
variety P. pungens glauca
, Colorado blue spruce. See one on the north side
of the Old Union. An attractive tree at 828 Lathrop Drive was planted in 1964.
One of the two specimens at 225 Santa Teresa Lane is approaching 35 feet in height.
A mature specimen is adjacent to the garage at 775 Mirada Avenue; trees also can
be seen at 788 Cedro Way and 850 Esplanada Way. Many other cultivars of this formal
tree, which is the most popular spruce, are available, including interesting dwarf
and pendulous forms.
