List of hardy palms
From Wikipedia, the free encyclopedia
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 where true winter conditions occur, while a few others are native to the warmer parts of the temperate zone in southern Europe, and others are native throughout temperate and subtropical locales in the Americas and Oceania. A few of these temperate climate palms can tolerate hard freezes with little or no damage. Many of these "hardy" species can be cultivated in warmer parts of temperate and subtropical climates.
The cold hardiness of palms varies by species. The hardiest species are found in the tribe Trachycarpeae, Washingtonia, and Rhapis, with species which are found in the wild in areas where the mean temperature of the coldest month of the year is not much less than 5 °C (41 °F), and Trachycarpus, with species which are found in the wild in areas where the mean temperature of the coldest month of the year is as low as 0.2 °C (32.4 °F). Members of the above palms and other genera are sometimes grown in areas where they are not truly hardy, overwintering with the aid of various kinds of artificial protection.[1]
