I'm not certain, but I think this is the latest spring I've experienced as a midwestern gardener. I look out the windows and see so much snow still, and the ground beneath it is frozen solid. Highs in the 30's all week, and no end in sight. I know last March is was in the 70's and 80's this week, which was the earliest spring I had experienced. Scary because if we would have had a late freeze after that I could have lost A LOT of plants... but we didn't, and things bloomed swimmingly, and early. Here are some shots of early april last year in my Minnesota garden.
