Environmental Artist, Activism Protect Nature

Patterson Clark’s least favorite invasive plant is Japanese stilt grass. That’s because he hasn’t figured out how to use it in his art. Boiling it yields weak brown ink. Its fibers don’t make for strong paper. It’s not even good for fuel. “It got over here as packing material. If that’s your best use, you’re a pretty sorry little plant,” he said wryly.

I met Clark, a hyper-local plant patriot and environmental artist, over coffee, a brown brew whose use no one questions. American country music played in the background as he spoke about his mission to rid the world—at least the wooded area around his studio—of alien weeds. With authority and training from the National Park Service, he frees native species by harvesting invasive plants in a section of Washington, DC’s Rock Creek Park. Then he makes art out of them.

By day, Clark creates science graphics for the Washington Post. So think Clark Kent and Superman—for nature. Even their names are half the same.

Back in Arkansas, our Clark majored in biology, a broader field than his father’s botany. After studying conceptual art and painting as a graduate student at the California Institute of the Arts, he got caught up in the art of journalism.

“Visuals for newspapers must relate to a horizontal demographic. They have to appeal to people from a lot of different backgrounds. Fine art is oriented in the opposite direction. It has more of a vertical appeal, with a narrow audience, generally with an education in art. So I was won over by the egalitarian pursuit of journalism and focused my energies on that.” For a good while, he did op-ed illustrations for the Arkansas Gazette and Miami Herald. Until recently, he wrote the Urban Jungle column for the Post.

His superhero cape, or smock, was thus infused with environmental and social justice. By now, it’s well stained with the blood, or sap, of enemy plants.

Fine Invasive Art

Unlike stilt grass, most invasive species don’t flummox Clark. His website, Alienweeds, features not only finished pieces, but also the botany, chemistry, and environmental activism behind his art. Some of it’s quite complicated. For pigments, there’s Amur, or bush, honeysuckle, which yields turquoise, and leatherleaf Mahonia, which makes fluorescent yellow. To get purple, he crushes Asiatic dayflower, whose beautiful blue petals burst forth at dawn.

Out of white mulberry trees, Clark makes a bright, tough paper, perfect for prints. Paper mulberry, traditionally used in Japanese washi, is easier to harvest, but the pulp dries into a cream color, isn’t as brilliant as the stock he gets from its cousin. Armed with bamboo pens, porcelain-berry brushes, Norway-maple woodblocks, and other homemade tools, Clark minted “weed currency” out of his inks and papers. He determined the denominations by the number of invasive plants in each.

For carving, a favorite is Callery pear, whose blooms whiten the margins of highways come spring. Its well-known hybrid, the Bradford pear, hardly stayed sterile. Look nearly everywhere in forty-two U.S. states, and you’ll find Ailanthus, the so-called Tree of Heaven, rightly dubbed the “stink tree.” It contains a ton of water and tends to warp, check, and cup. But once its honey-colored wood stabilizes, Clark can plane and carve it to reveal its brown grain. Like Irish ivy (not to be confused with English ivy), boiling it drives him from the house for the funk.

Bad Plants

Both species are evil-smelling, evil-doing varmints of the plant kingdom—according to most environmentalists. And we humans are in part responsible for the infestations. Yes, every species has a use and, certainly, a right to exist, somewhere. Many are quite attractive. But what seems like a good green introduction in one era proves disastrous later on.

Take Ailanthus again: American botanists found it standing tall on Chinese temple grounds, alone, it turned out, because its roots released a noxious chemical that retarded the growth of surrounding plants. Ditto here, where, unlike most plants, it thrives on road salt and knocks out every native around it. If you whack back its branches, even its young trunk—bam—it comes back with a vengeance. Never mind all the seeds.

Invasive plants breed like rabbits. They spread quickly, often with little interference from hungry animals and diseases. Their weaponry includes runners and rhizomes and countless survivalist seeds with myriad methods for dispersal. Although native animals prefer to dine on indigenous species, they do eat invasives and poop the pips.

Birds drop them, while mammals amble about with pods stuck to their feet and fur. Kernels wedge in our shoes and dangle from our tractor blades. They muck up our mulch. Once mature, the invaders degrade ecosystems by competing with native plants for resources and pollinators. Rare species disappear. In no time, diverse landscapes turn into manic monocultures.

Clark removes the troublemakers. “My first act is always one of environmental restoration.” Usually, other non-natives grow in the spaces he frees, but some local wildflowers will take down stilt grass, unless deer devour them first. The Park Service has its own invasive-plant treatment programs. He can’t interfere by, say, sowing native seeds.

Invasives Anyone?

Like other environmentalists, Clark doesn’t favor using gasoline-powered tools and herbicides to manage the bad guys. “There’s a fellow in North Carolina who uses the Boer goat, a meat goat. He takes them into kudzu patches, and they fatten themselves up on the vine. They love it. He just keeps hammering with the goats until he exhausts the kudzu, without using a lot of poison or disrupting the ground. Why not provide food for people?” Japanese, who can claim kudzu as their own, and, increasingly, Americans in the Southeast make jellies, tea, even noodles from it.

Clark is an invasivore, too. He eats the grape-like, blue berries of leatherleaf Mahonia, which are loaded with vitamin C. Then there are the raspberry-ish wineberries, sold at posh farmers’ markets. Mulberries, the dark ones with native red genes, are tasty. They’re juicier than pure white mulberries but not as sweet, according to Clark. Garlic mustard, before it bolts, cooks into a delicious winter green. Pair it with a slab of invasive feral hog, deer, or Canada goose—if you’re into meat. In that case, best to slug some Mahonia juice first: like other members of its family, it contains berberine, an antimicrobial.

Educational Outreach

When hunting down art supplies (or foodstuffs), dog walkers and park goers sometimes spot Clark. He estimates that one out of ten people asks him what he’s doing. “I tell them what I’m up to. Mainly, they give me a wide berth. Dogs get weirded out by me and start barking. So people finally come over and put their dog on a leash. Sometimes they’re curious.” More receptive are the Weed Warriors, gardeners, scientific and botanical illustrators, environmentalists, and art and science students to whom he speaks regularly. Nurserymen, still intent on selling homeowners some of the nasties, haven’t asked him to share.

Right now, he’s working on a calendar for the American Printing History Association. He’s producing 136 sheets of paper for the month of May and designing an image to print with verse by his sister, a poet. In September, he’ll take off for SUNY/Fredonia to deliver a series of lectures on art and invasives.

Unlike Clark Kent, though, Patterson Clark rarely flies. Environmental artists and activists like him don’t like fossil fuels. But they do drink caffeine. So powered by an Americano with extra shots, he bade me goodbye to return to his day job. Like Superman, he was ready to save the forest floor with his handsaw, to make art from the vanquished.

    This is a fascinating and informative article! By converting invasive plants into expressions of beauty, Patterson Clark offers a unique fusion of art and environment.

    I paint with oils, depicting native and invasive plants I’ve encountered in wilderness area, vacant lots, and on the edges of my own back yard. Through color and gesture, I convey the exuberance and resilience of things that grow wildly without invitation or cultivation. I invite you to visit my website, http://www.lorriefink.com.
