The last few days have been both very cold and very warm. We have had highs close to the 60s and lows in the 20s. This one morning the temperature dropped into the mid-20s and the ground was frozen and I noticed that frost had decorated the Vinca outside my window. I took a quick photo or two, but this was the only one that came out showing the frost. I am going to watch more closely in the future, perhaps we will see some more of the work of this fierce artificer.
