The Pacific Northwest area of the
North America includes the
northern area of California, the states of Oregon and Washington and
the southern area of British Columbia,
Canada. In this rather northern region, the climate is moderated
by warm Pacific Ocean currents which allow a very wide range of
plant material to flourish. Many plant species were "discovered"
plant explorers in this region and were
then introduced to the rest of the world.
