As I watched TV in the evening, I visited numerous websites on my laptop and got lots of ideas for winterscaping. Many gardeners use perennial grasses for visual interest. Shrubs with brightly colored berries or colorful stems are used as well. Some individuals craft seasonal planters to create a bright spot of color. A great variety of lighting can be used in the landscape -- from home-made ice candle holders to large spotlights that accentuate unusual shapes (a Corkscrew Willow , for instance) at night. Different lighting colors can create a variety of moods in the landscape. My sister-in-law, Sandra, placed twinkle lights on a large trellis by her deck. While sitting in her dining room, the trellis lights are very warm and comforting in the evening.
Decorative ice spheres can be created (of any size) and back lit with colorful lights. The spheres can be made by filling a balloon with water, placing it outside, and letting it freeze. The next day the balloon covering can be removed and you have a frozen decorative sphere. This could be a fun project for your kiddos or grands.
At any rate, I'm armed with lots of ideas and I've got a list! Next winter I will be thinking about winterscaping my yard come November instead of February.
