Palmettos in the Landscape

Saw palmettos in my front yard provide a bold tropical statement. Also, cinnamon ferns have put out their fall fertile fronds in this fall photo.

There's nothing like a palm or palmetto to add a bold, tropical touch to your landscape. We are lucky that the previous owners left several saw palmetto (Serenoa repens) thickets when they cleared out the lot.

Once or twice a year we trim away the yellow and brown fronds to tidy these native plants, but no other care is needed. These dramatic accent plants are exceptionally easy to care for.

Several times, I've tried to transplant small offshoots from these plants with no success. I'll keep trying, though, because there are some areas where I'd like to start new batches at the edges of our meadows to provide better cover and more privacy. Several lots near us that used to be wooded have now been cleared, so our palmettos and other native shrubs on our property offer a much-needed haven for birds.

The Sturdy Saw Palmetto

The hard, recurved teeth on the stems (petioles) of the fronds give the saw palmetto its common name. When trimming away the old fronds, we wear leather work gloves and are careful where we walk because those teeth can gouge your skin. Palmettos make an excellent impenetrable border.

Despite their low survival rate when transplanted from the wild, palmettos are difficult to get rid of if you don't want them. The roots run deep and are extensive, so digging up a palmetto stand is a lot like work. It burns readily, but burning it will not kill it. Palmettos are fire tolerant and will sprout new growth within a week or two of burning. If you are in a high fire risk neighborhood, you should remove all palmettos within thirty feet of any buildings and keep them separated into bunches elsewhere so they don't offer a continuous source of fuel. Our neighborhood is not a high-risk area, but our palmettos are away from the house.

My bluestem palmettos

A friend gave me three bluestem palmettos (Sabal minor) a couple of years ago. They have survived and are now growing slowly. . .Oh so slowly. I've planted two of them near the front pond and the third is in a low spot near some sweetbay magnolias (Magnolia virginiana), but it will be a long time before they will make a "statement" in the landscape. Patience.

Palmettos are true palms, not like the sagos (Cycas revoluta), which I wrote about earlier. Sagos are cycads and not palms, no matter what people call them.

Palm Background

The blue palmetto is more closely related to the cabbage palm (Sabal palmetto), our state tree, than the saw palmetto, which belongs to a different genus. The scientific species name of the cabbage palm, "palmetto" confuses the issue of palm vs. palmetto. Generally, a palmetto is a shrubby plant. The trunk of a mature palmetto isn't usually vertical for more than few feet. The fibrous trunk grows either underground or it lies on top of the soil. While palms are not true trees, they do eventually develop vertical trunks. For the first five to ten years, a palm will look much like a palmetto while it develops a trunk. Once the trunk is established, the palm will grow vertically, but the girth of its trunk does not usually increase.

Palms and palmettos are monocots and do not produce wood like true trees, which produce new layers of wood each year: their annual rings. Palm trunks are more like a grass with bundles of woody tissue throughout. This means that palms do not have bark and cannot heal wounds like true trees. It's unfortunate that many palms in Florida are located in the middle of lawns and are injured at each mowing by lawnmowers and string trimmers. The gouges in the trunk will not heal and become entry points for insects and fungi. These wounds also weaken the trunk, so while palms usually survive hurricanes, injured palms may break off at the soil line. To save your palms, replace about 18 inches of lawn around the trunks with mulch, but don't pile it against the trunks. This also makes it easier to mow.

When cabbage palms are transplanted from the wild, they will generate a whole new root system. Hundreds of unbranched roots grow directly from the bottom of the trunk and only after the new roots have been generated will there be any growth of the fronds. This is why almost all of the fronds are trimmed off when they are prepared for planting and they are often staked for a few months to keep them upright. At no other time should green fronds be trimmed from a palm. Almost all of the cabbage palms used for landscape plantings are transplants from the wild because they take so long to get started.

There are two major classifications of palms and palmettos based on leaf (frond) shape: the fan palms and the feather palms. Our palmettos and the cabbage palms are fan palms where the stem (petiole) is bare and the frond is palmate or arranged so that each section of the frond is arranged like spokes in a wheel. A feather palm has pinnate fronds with the sections arranged along a center stem like (guess what?) a feather.

Using Palms

Over the years, palms and palmettos have been employed in many ways:
- The Seminoles used palm fronds in building their chickees and today thatched roofs made of palm fronds are still used as tropical shelters for restaurants, resorts, and campgrounds.
- Seminoles and others have used the palm fronds for weaving baskets and hats. The fronds also are a source for long, strong fibers that are used for rope and for other weaving.
- Herbalists have used saw palmetto berries for prostate problems, but studies have not shown this to be more effective than a placebo. (Our berries are used only by wildlife and I cannot vouch for any effects they might have experienced.)
- Florida's DOT encourages palm plantings along highways and in median strips for shade and traffic calming. Palms break up the long view and are thought to slow drivers down. Since they will not branch out, good visibility is preserved. Roots of palms don't increase in girth, so road and sidewalk surfaces last longer.
- Palm trunks were used in construction and you can see palms used as columns in a few of the older buildings at Flagler College in St. Augustine.
- Palm hearts are eaten and the cabbage palm got its common name because people thought the heart tasted like cabbage. Occasionally you can find whole palm hearts for sale, but mostly they are chopped up and canned. Since the heart is the only growing portion of a palm, you kill the whole plant when the heart is removed.
- Each spring thousands of palms are trimmed to satisfy the market for fronds on Palm Sunday.

One of these days I'd like to plant a few cabbage palms on our lot, but until then I'll continue to enjoy our palmettos.

Ginny Stibolt moved to northeastern Florida in 2004 and even though she's a botanist and lifelong gardener, Florida gardening was a shock. She started writing The Adventures of a Transplanted Gardener columns for the Times Union newspaper in Jacksonville. This is one of those columns archived here on Floridata.com for your enjoyment. Now she's written three Florida garden books published by University Press of Florida: Sustainable Gardening for Florida, 2009; Organic Methods for Vegetable Gardening in Florida with Melissa Contreras, 2013, and The Art of Maintaining a Florida Native Landscape, 2015.
