More Information About Rhapidophyllum
Needle palms get their name from the long, sharp, porcupine-ish needles produced between the leaves that protect new growth from foragers. Rhapidophyllum is more of a palm shrub than a palm tree. The main trunk grows to about 4' tall and is topped by large leaves on long petioles. The entire plant usually maxes out at around 9' tall. With great age, needle palms will take on a more tree-like form.
