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.

There is a great book, written by David A. Francko that I really like, it’s called “Palms Won’t Grow Here and Other Myths: Warm-Climate Plants for Cooler Areas”. It goes into the details on how you can grow cold hardy palms in zones 7, 6 and even 5. This is the perfect foundation book for the gardener who would like to see a banana next to his cherry tree and a palm between his maples. It got great reviews and 5 out of 5 stars rating on Amazon.
Light Req: Partial shade to Full sun.
Water Req: Moderate. The Needle Palm needs moderate watering but is very tough in a drought conditions after establishing.
Maintenance: Easy. To prevent nutritional deficiency, apply good quality palm fertilizer that has continuous release formula twice a year during growing season.
