Here's the first part of the yard to thaw: the spring that rises on the back slope and flows into the rain garden (and forms icy puddles beyond). Snow cover doesn't last long over this spot. Every year the configuration of damp ground changes in this general area. This year, there seems to be more dampness and more ground involved.
Despite the snow and ice, the blue flag irises seem to love this cold muck. Who knew you could be so happy standing outside all winter with your feet in icy water?
