Parts of it. Texas is a BIIIG state (and worth visiting - especially the parts that are not Houston). Even us d*** yankees know it.
my guess is the armeniacum and micranthum will be ok, the other two maybe not.
Not sure about the others, but the Parvi species should be all right. Many years ago, the late Dr. Jack Fowlie visited armeniacum habitat in China and it was so cold there, ice crystals had formed on the buds.
