We get plenty of the freezes here...it's an altitude thing. We are truly in the Hill Country of Texas. Last winter, of course, was an aberration, with lower temps than I'd seen in a long time. The nurseries did well in the spring, sold lots of plants to replace what died (or what people thought had died), either from severe drought (ended in the fall last year) or from cold. Many plants just came up extremely late this year, from the roots.
