I was out in West Texas today and snapped a few pics. Enjoy
These first washingtonia filifera were in Midland, TX and saw 8 degrees in 2011, with a daytime high of 18. i saw around 100 filifera around the midland area ranging from small plants to mature ones such as these. additionally there were a few trachycarpus and post 2011 robusta growing. I saw no more than 3 small, aweful looking sabals scattered around town.
