If you have a regular winter, with snow cover, you should have
much success with many of our plants.
If you live in a cold area with wind, try to be careful of
your planting sites and give them a little protection from this wind.
Desert temperatures are a wonder. There are plants out there
that I know have made it through -12 deg. F., (-16 C) but will freeze
out here at 20 deg. F.(-5 C.). They will not tolerate root temperatures
below freezing. In their area the ground does not freeze even at 0.
