There aren’t a lot of quality landscape plant options that fit the description nearly every homeowner desires: native, low-maintenance, slow-growing, pest free, drought tolerant while tolerating wet soils, loving both sun or shade, and green year-round. Needle Palm (Rhapidophyllum hystrix) is the rare plant that checks all those boxes and deserves consideration when adding plants to your landscape!

Needle Palm is an endangered native, growing in a narrow range in the coastal Southeastern US, Calhoun and Liberty counties included. It is primarily found in the understories of wet wooded areas along slopes, ravines, and bottoms; if you’ve ever hiked the Apalachicola Ravines or Torreya State Park trails, you’ve likely encountered Needle Palm in the wild! Being native is nice, but what makes Needle Palm an outstanding landscape option?
Needle Palm is the prettier, more refined cousin of Saw Palmetto (Serenoa repens), which it is sometimes confused with. Unlike the rambling, aggressive, stiff-leaved palmetto, Needle palm possesses “softer”, finely cut, lustrous evergreen leaves, allowing it to add amazing texture to any landscape. Also, unlike palmetto, it doesn’t need a yearly “cleaning” to prune out brown, dead leaves, rather its leaves persist green and clean for many years! You might not want to reach into the interior of a Needle Palm plant anyway, as generally unseen 6-8” namesake “needles” surround the base of its trunk. Needle Palm grows very slowly, eventually reaching 8’ tall or so, but is more often seen in the 4-6’ range in landscapes. This is absolutely a shrub that will never outgrow its welcome. It is a nearly trunkless palm, almost always appearing as a shrub, though with extreme old age it can begin to look a bit like a small tree with a muted trunk. With outstanding aesthetics and a low-maintenance growth habit, Needle Palm has a place in nearly any landscape.

In the landscape, Needle Palm does best when sited with some shade in the afternoon but also thrives in full sun. They appreciate regular water during establishment but survive on their own without any extra irrigation after! Needle Palm also doesn’t need much in the way of supplemental fertilization. They do look their best with a light spring application of a general purpose, slow-release fertilizer, but this is not required. Needle Palms are not afflicted with the pest and pathogen problems the much more commonly used non-native Sago Palms (Cycas revlolutas) attracts. I’ve grown Needle Palm for 6 years in the landscape and have never noticed any pest or disease issues. With Needle Palms becoming more common in the nursery trade, I don’t see a place in most landscapes for the inferior, high-maintenance, insect infested Sagos. If you want the tropical, textured look of Sagos, plant Needle Palm instead.
Needle Palm is an extremely attractive, low-maintenance Northwest Florida native plant that you should absolutely seek out and add to your landscape! If you want more information or have any questions about Needle Palm or any other landscape/garden topic, please give your local UF/IFAS County Extension Office a call. Happy Gardening!

Spring has arrived and so have the insects. Caterpillars are crawling around and one possesses a unique appetite.
Neodiprion spp. is the most common defoliating insect group affecting pine trees. In all, there are 35 species that are native to the U.S. and Canada. The redheaded pine sawfly, Neodiprion lecontei, is the primary species found in the Florida Panhandle.
Adult sawflies can be as large as 1/3 of an inch in length. The female can be two-thirds larger than the male and are mostly black with a reddish-brown head, with occasional white coloration on the sides of the abdomen.

The ovipositor, the tube-like organ used for laying eggs, is saw-like, hence the common name. During the fall, females make slits in pine needles and deposit individual eggs, up to 120 eggs at a time. The eggs are shiny, translucent and white-hued. Mature larvae (caterpillars), as seen in the accompanying photo, are yellow-green, emerge in the spring and feast on pine needles. After weeks of feeding on needles, the mature larvae drop to the ground. The cocoon, a reddish-brown, thin walled cylinder, is spun in the upper layer of the soil horizon or in the leaf litter; this is called the pupae stage. The pupae overwinter, and adults emerge from the cocoon in the spring of the following year.
Mature larvae are attracted to young, open growing pine stands. Pine is the preferred host, but cedar and fir, where native, are secondary food sources. Neodiprion lecontei is an important defoliator of commercially grown pine, as the preferred feeding conditions for sawfly larvae are enhanced in monocultures of shortleaf, loblolly, and slash pine, all of which are commonly cultivated in the southern United States. Defoliation can kill or slow the growth of pine trees as well as predispose trees to other insects or disease.
Are there control methods? Yes, biological control is a major factor, as natural enemies are numerous. Disease, viruses and predators help regulate population control. For small scale control, physically removing eggs or larvae is key. Again, most infestations occur on younger tree plantings, so they’ll be in reach. Be sure to scout young pines for signs of infestation. Horticultural soaps and oils are effective chemical controls, if needed.
For more information, contact your local county extension office.

It’s always fun to add new plant to the landscape. And it’s even more fun to propagate your own plant material. The question is, what plant propagation method is best? The answer depends on a number of factors such as:
- How much time and money is available?
- Is a uniform crop desired or is trait variation preferred?
- What is the plant species being propagated?
Plants can be propagated either by seed (sexual propagation) or by segments of vegetative material (asexual propagation). Sexual propagation takes far less time and effort because new plants are being started from the seeds (offspring) of parent plants. This type of propagation promotes genetic diversity because offspring may not have the exact characteristics of the parent plants. Sexual propagation increases the possibility of hybrid vigor, which is the improved quality of plant material to that of parent plants. Asexual propagation usually takes more time, but generally ensures that propagated plants will maintain the same characteristics as the parent plant. For some species it may be the only way to pass on desired traits to subsequent generations and it may be the only way to propagate certain species. A plant produced vegetatively can become larger than a plant produced by see in the same amount of time.
Tips for Successful Sexual Propagation
- Seed Collection – Seeds should be collected when fruit is ripe, just before they fall to the ground. In general, seeds should be cleaned, dried, and stored at 40 degrees Fahrenheit (in a refrigerator). However, palm seeds should be planted immediately after harvesting and cleaning.
- Seed Dormancy – Some seeds have thick seed coats the inhibit germination. Some seeds need to be scarified (breaking of the seed coat) and/or stratified (stored in a specific environment) in order to germinate.
- Seed Sowing – Seeds can be germinated in flats or other suitable containers in a seed starting media. Seeds should be planted at a depth of two to three times their diameter, but no deeper than 3 inches. Cycad seeds should be planted just below the medium surface.

Tips for Successful Asexual Propagation – In general, asexual propagation is the propagation of plant material from cuttings of stems, leaves, and/or roots.
- Rooting Hormones – Increase rooting percentage, hasten root initiation, increase the number of roots per cutting, and increase root uniformity. Auxin based rooting hormones (Indolebutyric acid (IBA) and Naphthalenacetic acid (NAA)) are available in dry or liquid forms. It is important to use the correct concentration for the particular plant species because over application can cause damage to cutting base.
- Sticking Cuttings – Cuttings should be stuck in the medium only deep enough to support the cuttings and hold them upright (1/2″ to 1″ deep).
- Post-Rooting Care – Fertilization should be applied as soon as roots emerge from the cuttings. However, overfetilization can increase soluble salts and burn roots.
Examples of Asexual Propagation
- Softwood Cuttings – Taken from woody plants usually three to four weeks after a new flush of growth. Commonly propagated species using this method include: crape myrtle; magnolia; oleander; azalea; jasmine; and boxwood.
- Semihardwood Cuttings – Similar to softwood cuttings, but the lower portion of the cutting has become lignified (woody). Usually taken from new shoots six to nine weeks after a flush of growth. Commonly propagated species using this method include: camellia; pittosporum; junipers; and some hollies.
- Hardwood Cuttings – Taken from the previous season’s growth, just before or during the dormant period. Commonly propagated species using this method include narrow-leaved evergreens and deciduous species during the dormant season after leaves have dropped.
- Leaf Cuttings – Comprised of only the leaf blade or the leaf blade and petiole (leaf stalk). Cuttings are stuck upright in the propagation medium with the basal end (petiole end) of the leaf inserted into the propagation medium. Commonly propagated species using this method include begonias and peperomias.
- Root Cuttings – Taken in late winter or early spring from two to three-year-old plant material. Plants propagated by root cuttings may not reproduce true to type if they are budded or grafted. Commonly propagated species using this method include: plumbago; bayberry; oakleaf hydrangea; and yucca.

Florida is home to some amazing and gorgeous plants that are underused and underappreciated in the home landscape. One such plant is an evergreen and easy-care large shrub or small tree known as black titi or buckwheat tree, botanically known as Cliftonia monophylla.

Black titi is commonly found in wet areas and at the edges of swamps in USDA hardiness zones 7B through 9A from Louisiana through the Florida panhandle and into South Carolina. This is a perfect plant for those areas of your landscape that are low and consistently moist.
Early spring brings clusters of small white flowers at the tips of the branches. Occasionally one can find the pink-flowered variety of black titi in the native nursery trade. These fragrant flowers provide an early season nectar source for bees in February and March. The flowers give way to golden-amber seed pods that resemble buckwheat. The seed pods turn a pleasing orange-brown and persist on the plant through winter. The shiny dark green evergreen leaves along with the seed pods provide an additional ornamental quality to the tree in fall and early winter.

Resurrection Fern on Pecan Tree. Image Credit Danielle Sprague, UF/ IFAS Extension
This week, I received a call about identifying a plant growing on a pecan tree in someone’s yard. With the recent rain we’ve experienced after a rather dry period, I had a pretty good feeling it was a resurrection fern. A quick picture sent in to me by the homeowner confirmed this.
Resurrection fern, Pleopeltis polypodioides is a native fern found in many hardwood trees throughout the southeast. In our area, it is found most often on the branches and trunks of live oak and pecan trees. The resurrection fern gets its name from its ability to withstand extensive periods of drought by shriveling up and appearing dead. When it is exposed to water again, it will ‘come back to life’, uncurling its fronds and appearing bright green.
This creeping fern has a long, skinny stem to which the fronds or leaves are attached. The stem is less than 1/12″ in diameter and fronds are anywhere from 4 to 12 inches long. Unlike other plants, resurrection fern reproduces by spores, not seeds. These spores can be found on the underside of the fronds in clusters known as sori. The sori look like brown to black scales.

Resurrection fern is a perennial epiphyte or ‘air plant’, meaning that it attaches itself to other plants, but it does not steal water or nutrients from its host plant. Instead, it absorbs water and nutrients that collect on the outer surface of the bark. One of the questions posed by the homeowner was the need to control the resurrection fern, however, since it is an air plant and does not harm the tree, there are no chemicals recommended to control it.
In 1997, the resurrection fern made its first debut in outer space! Because of its unique attributes, the National Aeronautics and Space Administration (NASA) launched into space for an experiment to study the ‘resurrection’ in zero gravity. Amazingly enough, they found that the resurrection fern was able to rehydrate and recover in zero gravity!

Master Gardeners demonstrate correct tree planting techniques.
Last week, we celebrated Florida’s Arbor Day. “What?” you may say—“Isn’t Arbor Day in the spring?” Well, yes and no. National Arbor Day is celebrated in the spring (April 24 this year), usually within a day or two of Earth Day. However, because of the wide range of climatic environments throughout the United States, each state has its own date based on ideal growing conditions. As it stands, Florida’s is the 3rd Friday in January, as we are situated so very far south. Alabama and Georgia, where so many of us north Floridians experience similar weather, hold their Arbor Days in late February.
Contrary to popular opinion, the optimal planting time for trees is not in the spring, but in fall and winter. Planting during dormancy allows trees to focus their energy resources on growing healthy roots. In the coming spring, a steady supply of warmth, sunshine, and pollinators will bring on leaf growth, flowers, and fruit.
Check with your local Extension offices, garden clubs, and municipalities to find out if there is an Arbor Day event near you! Several local agencies have joined forces to organize tree giveaway events and sales in observance of Florida’s Arbor Day.
Saturday, January 25th
Leon County: UF/IFAS Extension Leon County Master Gardeners will assist with the county’s Arbor Day tree planting at 9 a.m. Martha Wellman Park, 5317 W. Tennessee St., Tallahassee.
