Longleaf pine is a unique native tree


I admit I’m not like everyone else. Most people go to Florida to see Disney World or just sit on a sunny beach. Roberta and I drove down there for a wedding and stopped on the side of the road several times to take dozens of pictures of longleaf pine (Pinus palustris) at various stages of growth. I shot off several rolls of film.

At that time we hadn’t spent much time in coastal Carolina where there are also significant populations of the species. The longleaf pine range extends from coastal Virginia through Florida except for the extreme south. They also spread westward to easternmost Texas and substantially inland into Georgia and Alabama.

Longleaf pines are quite unique. They undergo a grass stage. I know of no other tree that does this. For one to seven years trees resemble a clump of grass. Long needles protect a white fuzzy growth tip.

Eventually, when roots have grown sufficiently, this bud shoots vertically and the tree develops. Long flexible needles in groups of three congregate at the tips of the branches. Young seedlings and limbs almost resemble bottle brushes.

Longleaf pine seedlings tolerate fire extremely well during the grass stage.  Sometimes at this time, seedlings may become infected with a fungus called brown spot needle blight. Needles shrivel and fall off. When infestations are severe young seedlings die.

This pine species generally develops straight trunks with few branches. It is the leading tree for utility pole production in the southeast. Wood density is high, making it stronger than most pines. Quality is far better than other common species like loblolly pine. Loblollies are the most common pine tree in North Carolina.

Longleaf pine also yields the highest quality pine straw for mulch. As the name indicates, this species has longer needles than any other pine species. Longer needles are easy to bale. They also keep their shiny reddish color longer. These needles last longer too, so re-mulching is less frequent.

Probably the biggest reason longleaf pine isn’t used more in pine plantations is that it can be difficult to establish. Proper planting depth is critical as are moisture levels and planting time. Once established, trees grow exceptionally on otherwise poor soils.

Like nearly all pines, longleafs are what we call shade intolerant. This means seedlings require sunlight to grow. One rarely finds young trees amongst older ones. That’s a major reason why pines are adapted to a clear-cut type harvest system. Eventually, if we selectively cut them we would have none left, since we wouldn’t reduce shade sufficiently.

Longleaf pines have other uses as well. Large cones are often used in crafts. They can be the size of footballs. Longleaf pine resin is antimicrobial and in a pinch can be used to dress cuts and scrapes.

Those desiring to increase their intake of vitamin C might wish to try pine needle tea. Steep a handful of green needles in hot water for a few minutes and enjoy the unique flavor. Too much might give your kidneys a workout. It’s also a fairly strong diuretic.

About tedmanzer

I grew up in Old Town Maine and got a B.S. at the University of Maine in Plant Sciences/ minor in Botany. From there I moved to West Virginia and earned a M.S. in Agronomy at WVU. I also met my wife there. She grew up in rural WV as the daughter of tenant farmers who raised cattle and hogs. Their lifestyle at times was one of subsistence and I learned a lot from them. I've always been a foraging buff, but combining my formal botanical knowledge with their practical 'Foxfire-type' background opened up my eyes a little more. I now teach agriculture to high school students at Northeastern High School in Elizabeth City, NC. My wife teaches with me and we make a great team. I also write a weekly nature/foraging column for the local paper (dailyadvance.com) and frequently publish articles in several other newspapers in northeastern North Carolina. I also have written several Christian nature/adventure novels that I plan to publish eventually. One is a five book family saga I call the 'Forgotten Virtues' series. In the first book, Never Alone, a young boy comes of age after his father dies in a plane crash, and he has to make it alone. Never Alone is now available in paperback, Kindle and Nook. The second book, Strange Courage, takes Carl from his High School graduation to his recovery from a nasty divorce. The third book, Second Chances, takes Carl from his ex-wife's death and the custody of his son to his heroic death at age 59. The fourth book, Promises Kept, depicts how his grandchildren react and adjust to his death. In the final book, Grandfather's Way, his youngest and most timid granddaughter emerges from the shadow of her overachieving family and accomplishes more in four months than most do in a lifetime. I use many foraging references with a lot of the plants I profile in these articles in those books.

    Didn’t someone just write about this? I know it is a common tree within the natural range, but it is fascinating here because we do not have anything like it.

      I don’t know. I wrote this for my newspaper column a few weeks ago and just got around to posting it here.

        Yours looked different. It obviously was not the same article, but I know I read about it somewhere. I do not write much about our native pines because we do not use them in landscaping. I still like the Monterey pine, because they were more common when I was a kid. They do not fit into modern urban gardens though.
