Bitter cold may impact plants, especially "marginal" shrubs

One cost of the bitter cold may not show up until Spring -- and involves your plants.

With the mild winters we've had, garden centers say people have put in more "marginal" shrubs -- varieties that don't fare well in a deep freeze.

The top tree in trouble is the Japanese Maple.

Broad leaf evergreen types of rhododendron and azalea could also be in trouble.

There have been a number of new cold weather varieties of hydrangeas coming out and they're so new that no one knows how they'll hold up.
