I took advantage of the nice weather we're having and decorated my front window box so it won't be empty during the winter. I usually just put evergreens in there for the holidays and they stay green for several months. Thought I'd do something different this year and added sedum, grasses, Ivy and a couple dried hydranga. I don't know how long that other stuff will last, but hopefully I can add more evergreens if need be. DD suggested I spray it with Wilt-Pruf to help it keep from drying out too much. It looks nice looking out from the inside too. Something green to look at during the winter.

What do you do with your boxes for winter interest?
