Species:hystrix

Family:Arecaceae

The Needle Palm is a compact, temperate palm that reaches a height of up to 5 feet, characterized by its dense, shrubby appearance. This nearly trunkless palm can endure brief periods of sub-zero temperatures, making it resilient in the Southeast. Its sharp spines can make relocation difficult once it is established, posing a risk to both humans and animals. While its natural habitat consists of the swampy regions of the southeastern United States, this species is currently endangered. The leaves closely resemble those of the Trachycarpus. Often utilized as a specimen or potted plant, the Needle Palm demonstrates drought resistance once it is well-established. It can thrive in wet soil and full sunlight but shows a preference for partial shade. This palm grows slowly and is recognized as the most cold-hardy variety, spreading through suckers. It is rarely affected by deer and has moderate tolerance to salt.

**Form:** Spreading clump; trunkless shrub
