Three weeks ago Johnny-jump-ups were still blooming from last fall, snowdrops were coming up and Helleborus niger was in bloom but the blossoms were still bent down and not yet all the way expanded. Since then we've had more -20F temperatures with no snow cover and more snow and ice. I don't know what things are like under the snow.
The reason it feels like spring is that we have done the bulk of the tapping of the sugar bush at Maple Grove Farm (where I live), boiled a little and are waiting for sap to flow. Once we do the tapping it feels like spring no matter how cold it still is.
