What can I do with flower boxes in winter?
I have two flower boxes that look like these on the fence in front of my condo.
(These aren't mine - just an online photo)
In the spring, summer, and fall I have seasonal flowers, but in the winter I normally just take them down.
Now that we're showing our condo to sell, I'd like to keep them up with some kind of wintery flower/decoration/something. It doesn't actually have to be a plant - I'm open to all sorts of ideas!
