Scientific name: Rhapidophyllum hystrix or Rhapidophylum hystrix

Common names: The Needle Palm is also known as Porcupine Palm.

Family: Arecaceae

Origin: It is native to the southeastern United States.

Appearance: It doesn’t form a trunk, instead has stems growing very tightly together from a single base. Stems are slender, about 6-7 inches in diameter.

Leaves are palmate, or fan-shaped, deep green color, about 2ft long and 4ft wide. About 10-13 leaves grow on smooth petioles 2-3ft long, covered with fiber and numerous sharp needle-like spines produced between the leaves. Fiber husk protects the palm from cold winter weather conditions. Spines grow to about 3-4 inches long, very slender, range in color from dark brown to black. They protect the stem growing point from browsing animals. Each leaf has about 10-16 leaflets 18 inches long and 2 inches wide, with square tips.

Flowers/Fruits: In spring or early summer, the Needle Palm produces small yellow to brownish flowers that grow in clusters at the top of the short inflorescence. The Needle Palm is dioecious, male and female flowers are born on separate plants. Flowers are followed by fleshy drupes. Fruits are oblong, fuzzy, reddish-brown, about 1 inch in diameter. They grow close to the petiole surrounded by fiber and sharp needles.
