This is the first day I have had the inclination to look at my plants out in the yard. Ice storm, 8F weather for days, wind chills to -13F and my CP's look pretty good. None of them is rated to the temps we had here in North TX. The bad thing was that the cold didn't last a few hours or half a day like normally, it was a long, deep cold spell. These plants are in small pots, out on patio with no protection from the ice, strong winds or temps. I even have one tiny VFT that survived this in a 4 inch pots and I swear the little trooper has some tiny leaves that are green. Too early to tell about my volunteer D. filiformis but the resting bud felt firm and looks alive. Anyone who says they are difficult to grow has not researched their growing needs. They are amazing.
