Winter has settling in my gardens in Omaha.  Since my personal garden is small I have to enjoy the joys of big color in the gardens I design for others.  I recently went to one of my larger properties to cut some stems for my winter pots.  I was so pleased to see the display of Redtwig Dogwood (Cornus sericea) against the evergreen foliage of various varieties of Spruce (Picea sp.).  What are the favorite colors of winter in your area?
