In particular, small to medium sized perenials? I planted a small border from scratch this time last year and was fairly pleased with how it looked April - August. I'm picking up some Anemone, Muscari and Aconites to spice up the first few months of the year, but I need some more Autumn/winter interest I think.
I have some small evergreen shrubs as a backdrop and have a few evergreen carpet plants like creeping thyme and cotton lavender. The Rudbeckia are still looking good, but I could do with a plant or two which would look nice next to it. Any suggestions?
