Why not consider the dry dead foliage of plants as architectural beauty in the winter?
Just because the fall has come and winter is either already here for you personally or just around the corner the garden is still something to be considered and acknowledged as something beautiful. Dried landscape material can be tied back like an artistic creation of architectural art in the garden. These photos were taken at the North Carolina Arboretum in Ashville where the beauty of fall splashes against the deep green background of Carolina evergreens.
These grasses and hydrangea would even be pretty covered in a light blanket of snow.
Tip: A nice balance of grasses against a back drop of evergreen looks great in every season.
