HINTON, W.Va. -- If you want to visit Enchanter's Garden Native Plant Nursery, be sure to call ahead to fix a time.
Because if you meet another vehicle on the rocky, half-mile-long, one-lane driveway that leads there, somebody will have to back up to where they started. With a steep, eroding cut bank on one side and a close drop-off on the other, that's not a savory prospect.
But upon arriving at the top of the road, the land opens up to a nursery with a greenhouse full of wild and a few rare plants, and a business that is itself an uncommon species in the southeastern United States.
Self-taught native plant expert Peter Heus and his wife, Andy Klopp, founded Enchanter's Garden on about six acres of their 200-acre homestead in 1994 and operated it until Heus retired in March. Ian and Elizabeth Caton moved to West Virginia from Philadelphia to take over.
Today the nursery offers at least 200 varieties of native and wild plants propagated from seeds or cuttings taken from ditches, slopes and river banks on public and private (with permission) lands around the region.
Now it is the Catons who staff the Enchanter's Garden table for a few summer Saturdays at the Blacksburg, Va. Farmers Market, and at other markets and festivals where for many years Heus and Klopp were familiar faces.
"We just want to have fun, make a little money and enjoy our lives, basically," Ian Caton said. The goal is to "not make this place a burden on our nerves."
That desire to simplify looked to be in full flower on a recent Tuesday, when Elizabeth Caton was out back of the greenhouse, elbow deep in pine bark mulch with a cat lazing beside her.
All the plants offered by Enchanter's Garden are native to the eastern U.S., and most are native to Virginia and West Virginia. But Caton said the business sub-specializes in plants that grow on what are known as shale barrens.
Also known as "shale ridge balds" or "shale ridge prairies," shale barrens are rocky outcrops and slopes "endemic to western Virginia, eastern West Virginia, west-central Maryland, and south-central Pennsylvania," according to the Virginia Department of Conservation and Recreation.
These hot, dry and sometimes treacherous patches of soil-poor, decomposing rock nurture a tough breed of plant that can tolerate heat, drought and fire. With their deep roots and hardy constitutions, shale barren species can make low-maintenance landscaping plants, Caton said.
The best known of this plant category are shale barrens buckwheat, shale barrens pussy toes and heart-leaved skullcaps. But sometimes, native plant collectors make thrilling discoveries.
Near the greenhouse's grassy parking area sits a mysterious plant that is not for sale.
"I hope someone who comes and sees it will know what it is," Caton said.
Because neither he, nor Heus, who discovered it on a shale barren about six years ago, knows exactly what it is. They're sure it's a species of bee balm, but as far as they can tell it's heretofore remained undescribed by botanists.
This, too, is part of the Enchanter's Garden mission: to find and preserve the waning biodiversity of the southern Appalachians.
Invasive species such as the hemlock wooly adelgid have already begun to change eastern forests, killing swaths of native trees. In their place, invasive plant species can thrive.
Simply preserving land is not a guarantee of saving natural ecologies, Caton said.
Heus and Caton battle introduced species like tree of heaven and garlic mustard. Overpopulation of white-tailed deer is also a problem. In great numbers the native herbivore can damage native plant colonies in the forest and on the nursery grounds.
A century of fire suppression in the eastern forests is another problem, Caton said.
For much of their recent past, Appalachian forests were shaped as much by fire as by water. Native plants in the eastern woodlands evolved with regular forest fires caused by lightning and intentional fires set by generations of American Indians to clear and maintain meadows that attracted game and made way for farming.
Without fire, some native plant species can't thrive, Caton said.
For this reason, Heus and Caton do controlled burns on the nursery property.
