Geranium macrorhizum foliage is scented FG and, in a mild winter, turns red and stays until spring when it can be tidied up in time for flowering and fresh green foliage..
I cut all my geraniums back, regardless of type, once they finish their first big flush of flowers. I just cut them all back to an inch or two, scatter on some general purpose fertlitiser such as pelleted chicken manure and water them. In 3 weeks time they'll have grown back fresh, healthy leaves that look good with our without new flowers.
My scented leaf pelargonium has only flowered once and that was years ago. Now I keep it pruned and tidy so it has fresh leaves for my ice cream infused with its foliage. The flowers are really insignificant anyway.
