Rhapidophyllum is a genus with one species, the needle palm (Rhapidophyllum hystrix), a clumping fan palm native to the subtropical southeastern US. It is prized for its exceptional cold hardiness and needs hot summers to do well.
Rhapidophyllum hystrix, the needle palm, is a palm native to coastal margins of the subtropical eastern Gulf and south Atlantic states of the United States. Populations can be found from coastal southeast South Carolina, southward to Florida and west across the coastal plain of Mississippi and southern Alabama. It is one of the most cold-hardy palms in the world, and can be found growing in several areas with warm temperate climates.
The needle palm is very popular among palm enthusiasts in temperate climates for its ability to tolerate modest cold. Some reports have claimed survival of temperatures as low as −26 °C (−15 °F) with heavy damage, but with the palm recovering. More realistic estimates are closer to −21 °C (−5 °F) with foliar damage. Recovery of winter damage of needle palms is much more precarious in climates with cool summers like the Pacific Northwest and northwestern Europe.
In the United States, needle palms are reliably cultivated along the East Coast from Florida to Connecticut, and along the entire West Coast from southern California to Washington. Across the interior of the USA, large well-established specimens have been growing in Tennessee, the southern Ohio Valley, and Washington, DC at the United States National Arboretum since the 1960s. It is the most popular landscaping palms in the Chesapeake Bay area of Maryland. Needle palms need hot summers to thrive and the species does not grow well in the cool summer climates.
