#1 MEDITERRANEAN FAN PALM, Chamerops humilis
Med fans are cold hardy to 16-17 degrees – and thought to be hardy as low as 0 degrees. I do know that they suffered little damage in Dallas during the winter of 2010 – and those temps dropped into single digits! They are a short multi-trunked, fan-leafed palm. Meds make a great accent and also work in a foundation planting. They also come in a silver cultivar. For more information, click here or here for info on silver meds.
