A Floridata Plant Profile 93 Rhapidophyllum hystrix

Common Names: needle palm, porcupine palm Family: Arecacea (palm Family)

needle palms
Needle palms are perfect for very shady areas. Jack likes to grow them beneath live oaks where they thrive in the cool shade and will make rapid growth if treated to occasional irrigation.


The needle palm is a terribly talented plant that is beautiful, rugged, extremely cold hardy, fast growing and one of my landscape favorites. Rhapidophyllum hystrix is a small shrubby fan palm that grows to about 6 ft (1.8 m) in height. It produces suckers freely, these multiple stems creating an ever widening rounded clump of indeterminate width. Over time the tightly packed stems will form an impenetrable thicket. The needle palm doesn't form a trunk but instead has a slowly lengthening crown that may grow to about 4 ft (1.2 m) long and about 7 in (17.8 cm) in diameter. The stems are composed of old leaf bases, fiber and long slender spines. They are usually erect but in older clumps they may lean or grow prostrate along the ground as they compete for light and space. As each stem matures, more slender spines grow from from between the leaf attachments. These "needles" are dark brown or black, very slender and sharp and grow from 4-10 in (10-25 cm) long.

Each stem carries about 12 erectly held leaves that are about 4 ft (1.2 m) long. The foliage is glossy deep green on top with a dull silvery white underside. The slender petioles (leaf stems) are smooth and are 2-2.5 ft (0.6-0.8 m) long and 30-36 in (76-91 cm) wide. The fan-shaped leaves are deeply indented with each leaflet 1-2 in (2.5-5 cm) wide and 15-20 in (38-51 cm) long. The tip of each leaflet is bluntly squared off and notched as if trimmed with a pinking shears.

needle palm leaves
These two needle palm leaves illustrate the two forms of needle palm that differ in average number of leaflets and tendency to produce suckers.

The needle palm has a tightly compact inflorescence (flower structure) that is about 6-12 in (15-30 cm) long and held close to the stem, barely peeping above the leaf bases. Obscured by foliage and fiber and protected by the sharp needles it is often not visible without serious effort. Tiny yellow to purplish-brown flowers are held on the inflorescence with male and female flowers borne on separate plants (although hermaphroditic individuals are also reported). This palm flowers irregularly with blooms typically appearing in spring and early summer.

I have observed (and grow) two forms of needle palm that have slight differences in form and foliage. One form is shrubbier, suckers more and has leaves with smaller leaflets that are in greater number. The other tends to sucker less, has larger crowns, with fewer leaves that have fewer, but wider leaflets. I've observed the shrubbier form in North Florida growing on hillsides while the other form seems to be more common in Central Florida where I've observed it growing on flat, moist forest floors.

needle palms
These needle palm are growing on a hillside in a forested ravine along the Apalachicola River in the Florida panhandle, one of its natural habitats.

Needle palm seeds are red to brown and roughly spherical. They are about an 1 in (2.5 cm) in diameter and have a fuzzy fleshy covering. They are protected by the sharp needles and are difficult to access - since animals can't get to them and most die in place.


Rhapidophyllum hystrix is native to the southeastern United States. Populations can be found in Alabama, Florida, Georgia, Mississippi and South Carolina. Needle palm grows on shady wooded slopes as well as in moist bottomlands along streams.


Needle palm prefers fairly moist, well drained soils with lots of organic matter but is very adaptable to less than ideal conditions. Light applications of fertilizer a couple of times a year in spring and summer will reward with faster growth rate. Light: Full to partial shade. Moisture: Moist, well drained but tolerant of dry conditions. Hardiness: USDA Zones 8 - 10. Needle palm might very well be the worlds hardiest palm. I once saw a very handsome specimen enduring a blanket of snow in a Georgetown front yard in Washington, DC!. Propagation: By seed or by division of clumps. Although it takes a lot of effort to dig and separate a large needle palm it is relatively easy to successfully transplant the suckers. Seeds germinate in about 6 to 12 months. I regularly scan beneath my needle palms for the occasional seedling. I dig these, pamper them in a pot for about a year before planting them in landscape.


The needle palm is a perfect, low maintenance plant that makes an excellent specimen plant for small spaces near the patio or entryways. In the shade garden the needle palm provides a rich green backdrop of flowering plants and it blends beautifully with azaleas and camellias in the filtered light under a high canopy of pine.

Mass plantings of needle palm can also serve as security hedges. The thick growth and lethal needle form and impenetrable barrier that will deter most creatures, especially human.

Established plants are drought tolerant and are perfect for shady xeriscape plantings. Surprisingly the needle palm is also happy to grow in wet soils and can even survive flooding and standing water. Use near ponds and streams and swampy forests. Needle palm is also useful around swimming pools where it's clean habit and ability to take continual splashes with chlorinated water make it a good choice although don't plant too close to walkways so passersby aren't pricked by the nasty needles.

Being one of (possibly the) most cold hardy palms, gardeners in cooler places can add this pretty palm to their plant palettes. It won't successfully grow in places where the ground often freezes, but in locations like Atlanta, Georgia; Portland, Oregon and Vancouver, British Columbia the needle palm can be planted in protected areas to everyone's evergreen delight!

needle palm
Jack spent more than five hours digging and separating this needle palm. After a trench was dug around the clump an ax was used to chop apart the suckers. The long iron bar at right is used to lever suckers up and away from the main clump of which only a quarter still remains in this photo.

The needle palm grows happily in containers and although not often seen used as such, it is durable enough to grow indoors if you have the space to accommodate it.

Plantings of needle palm are able to trap and "swallow" fallen leaves and other debris. There's no raking and this "automulching" further reduces maintenance - I told you this was a talented palm!


Needle palm competes with the Mazari palm (Nannorrhops ritchiana) for the title of "Most Cold Hardy Palm". In my experience, at least here in the southeastern USA, the Mazari palm is not even a contender. It is a desert palm from Central Asia and tends to fall prey to fungus diseases following cold spells while the needle palm is unfazed by both freeze and disease. Likewise I suspect that the Mazari can probably "out survive" the needle palm in cold arid areas.

R. hystrix is the only species in the genus Rhapidophyllum. You may see this palm referred to as Chamaerops hystrix, which is a synonym, in some older publications. It was formerly considered to be in the same genus of that other cold hardy dwarf, the European fan palm (Chamaerops humilis).


The state of Florida lists needle palm as endangered because it is "commercially exploited". NEVER transplant the needle palm from the wild because it is irresponsible and illegal.
