which season?

So I am pretty well convinced that it is fall. There are leaves coming down all over the place, especially in yesterday's wet, windy weather. It gets cooler each day. The days are getting shorter - or at least, the amount of daylight in each day is decreasing.
But look at this!

This is a skunk cabbage! And I took this picture less than an hour ago!
I thought skunk cabbage was a SPRING plant. I'm not sure exactly what this means, but I am very surprised and curious. It has not been a particularly warm fall. I don't think that the flies that act as pollinators for skunk cabbage are still around. I found three of these today, the first by accident as I was inspecting the edge of my stream, and the subsequent two when I searched for more. Will they last in this stage through the winter? Are they mutants? Is it the result of climate change? It will be interesting to watch...
