Pseudotsuga menziesii is
strictly a cultivated species in Wisconsin. It does
not escape from cultivation and is found only where it has
been planted. It is included in the list of gymnosperms
because it is a horticultural species in Wisconsin and because
it (along with Pinus nigra, Taxus cuspidata
and Picea pungens) is a useful addition to the small
list of native species of gymnosperms, for teaching purposes.
The needles are very similar to Abies balsamea, but
it can be easily distinguished from that species by the
cones which are pendulus, with conspicuous three-pointed
papery bracts clearly exposed beyond the stiff scales that
remain intact at maturity. The cones of Abies balsamea
are born upright on the branches, lack the conspicuous exserted
bracts and the scales fall off the axis of the cone at maturity.
Pseudotsuga menziesii is
a species of the western United States from British Columbia
and Alberta to California and along the Rocky Mountains
south to New Mexico and Arizona. It is not particularly
commonly planted in Wisconsin, but appears to be perfectly
hardy where cultivated.
