Needle Palm trees may be the most cold hardy palm on the planet! They have the ability to withstand brief temperature dips down to approximately -15 F with little to no damage.
With some protection, Needle palms can possibly survive even colder temperatures.
Due to their tolerance for such frigid temperatures, they are quite popular in areas where other palm trees wouldn’t survive.
Let’s take a closer look at this amazing palm and find out if it will be a good fit for your climate.
What Are Needle Palm Trees?
The Needle palm, known by its botanical name Rhapidophyllum Hystrix, can thrive in many growing zones across North America and Europe.
They are native to the southeastern U.S. from the southern Atlantic coast and west into Alabama and Mississippi.
It is a slow-growing shrubby palm getting up to 6 feet in height and 5 to 6 feet in width with a dense crown of fronds.
The glossy green palmate fronds can reach up to 6 feet in length.
They emerge from several stems from a single base and are covered in sharp needles up to 6 inches in length.
Needle palms will develop a trunk, but with their glacier slow growth rate, this can take SEVERAL years.
Needle palms are dioecious, meaning that male and female flowers will grow on separate trees to make viable seeds.
They are suckering palms and propagation can also be achieved by separating the suckers and planting separately.
Where Will Needle Palms Grow?
Needle palms enjoy hot, humid conditions and thrive in lowland swamps.
They are hardy down to the high zone 6 range without winter protection.
Temps in zone 6 can regularly get below zero during the winter months.
While that is pretty impressive for a palm tree, they will have significant damage to their fronds at these temperatures.
These palms will need to be grown in areas with hot summers to get the most out of their growth.
They can be grown successfully in areas with cooler summers, but will also grow much slower.
For this reason, they are not highly recommended for mild Mediterranean climates.
Needle palms have become popular in areas such as the Pacific Northwest of the U.S. and Northwestern Europe, but can struggle during excessively cold winters.
They are grown throughout certain areas of the midwest and northeast U.S. with hot, humid summers and freezing winters.
Who Are Needle Palms For?
Needle palms are for anyone living in areas with extreme seasonal temps where many other palms may bite the dust.
Due to their limited height, they are excellent for growing underneath taller trees in the landscape.
Needle palms will tolerate varying amounts of sun if kept in warm areas.
These palms are relatively drought-tolerant and can adapt to a wide range of well-draining soil types.
They will also do well in moisture-rich, swampy conditions similar to their natural habitat.
Since these are wide, shrubby palms with excessively sharp needles, they can also be good for growing along fence lines. This is ideal for acting as a barrier for unwanted wildlife.
Needle palms are great for folks wanting a slow-growing shorter palm, but also have room for the palm to spread out.
Since the needles of these palms are very sharp, they are recommended for open areas away from paths like entryways and doorways.
Needle palms are relatively worry-free from pests and other diseases.
They can be subject to spider mites and mealybugs, but this can be maintained with proper soil care.
While highly moisture tolerant, Needle palms can develop yellowing fronds from over-watering.
This is more common in areas with long cool weather periods.
Over-fertilizing can also cause this, so only fertilize twice a year if needed.
As mentioned before, these palms develop very sharp needles, so great care is advised when planting near high-traffic areas.
Provide plenty of room and when handling, be sure to wear thick gloves to avoid getting stabbed.
The Wrap Up
If you live in zone 6 or higher and have always wanted a palm for your landscape, the Needle palm is a great solution to get you started.
Although very slow growing, taking several years to achieve a mature size, Needle palms are a very easy palm to grow.
They are great for beginners and with very little effort, will provide years of enjoyment for any palm enthusiast.
