Well, I wasn't too worried about a few of my plants I had outdoors, until this morning. I looked out the back window and saw a nice frost over my neighbor's yard. I looked out my side window and didn't see too much frost in my yard. However, when I went out to check on my posts, I found that all but the largest had frozen. So much for that low of 35°F last night. Seems to have gotten a bit cooler than they expected. Right now I am slowly thawing out my Red Dragon, a Green Dragon, and a few smaller pots of S. purpurea ssp. venosa. My D. filiformis ssp. tracyi also got a bit hard.
They should all be fine. They have slowly been going dormant waiting for this type of weather. The pots did not freeze totally as water still ran out when I lifted them from the shallow trays they are in.
I guess I am letting everyone know that is now that time of the year for dormancy and to get your pots protected from freezing. I wish I had taken a photo of my Red Dragon. It was very frosty and sparkled nicely in the morning sun.
