Overview
Rhapidophyllum hystrix is the needle palm, growing 36–72 inches (90–180 cm) tall and 48–96 inches (120–240 cm) wide as a clumping, trunkless palm. Dark green palmate (fan-shaped) fronds 24–48 inches (60–120 cm) across, divided into 8–16 segments. The species name 'hystrix' means 'porcupine' — sharp needle-like spines 4–10 inches (10–25 cm) protrude from the fibrous leaf bases and can puncture skin and gloves. Among palm species grown in North America, this species tolerates temperatures below 0°F (−18°C) and survives reliably in zone 6. The clumping form lacks a vertical trunk — fronds emerge from a dense, low, multi-crowned base close to the ground. Native to the southeastern United States, from southern South Carolina to central Florida to Mississippi, where it grows in moist bottomlands and swamp margins. Dioecious (separate male and female plants). Small dark olive drupes 0.5–0.75 inch (12–18 mm) on female plants. Non-toxic. Deer-resistant (the spines). Full sun to deep shade — tolerates a wider shade range than most palms. Adapts to clay, loam, and sandy soils. Tolerates wet soil (native habitat is bottomlands). Growth rate is extremely slow — 1–3 inches (2.5–7 cm) of height per year. Expensive in nurseries due to the slow growth rate. Remove browned fronds — handle with heavy leather gloves (the spines penetrate standard gardening gloves).
Native Range
Native to the southeastern United States, from southern South Carolina to central Florida to Mississippi. Found in moist bottomlands, swamp margins, and maritime forests.Suggested Uses
Grown as a specimen or understory planting in zones 6–10. Full sun to deep shade. Tolerates wet soil. The sharp spines require placement away from walkways and play areas. Containers of 10+ gallons (40+ liters). Non-toxic. Deer-resistant.How to Identify

Care & Maintenance
Care Guide
Full sun to deep shade. Adapts to clay, loam, and sandy soils. Tolerates wet soil (native to bottomlands). Zone 6 hardy — withstands temperatures below 0°F (−18°C). Extremely slow-growing (1–3 inches / 2.5–7 cm per year). Handle with heavy leather gloves (sharp spines). Non-toxic. Deer-resistant.Pruning
Remove browned fronds by cutting at the base with heavy leather gloves or gauntlet-length gloves — the 4–10 inch (10–25 cm) spines penetrate standard gardening gloves. No other pruning needed.Maintenance Level
