Hardy palms are any of the species of palm (Arecaceae) that are able to withstand brief periods of colder temperatures and even occasional snowfall. A few palms are native to higher elevations of south Asia, and a few can tolerate hard freezes with little or no damage. Many of these "hardy " species can be cultivated in warm temperate climates. The hardiest species are found in the genera Rhapidophyllum, Sabal, and Trachycarpus. Members of these and other genera are sometimes grown in areas where they are not truly hardy, overwintering with the aid of various kinds of artificial protection.
