Canby's Mountain-Lover

 


Canby's Mountain Lover (Paxistima canbyi), Scott County, Virginia.

Some plants are absolutely amazing. Canby’s Mountain-Lover (Paxistima canbyi) is one of those plants. Mountain-lovers hang from the high, dolomitic cliffs of western Appalachia, a now-rare plant often known as cliffgreen or rat-stripper. They grow over gorges where ricocheting winds push humidity and cooler temperatures from the creeks or rivers below to their dry, sunbaked home above. Glaciers pushed the species to these southern rock outcrops, and right now, they’re not doing so well. This lonely plant is one of the last representatives of Virginia’s S2 (less than 20 occurrences) population, quite literally dangling from a four-hundred-foot precipice. Luckily, few poachers can reach it without severely threatening their own lives (or without being caught).

An evergreen groundcover in the Celastraceae family, closely related to many tropical, ornamental shrubs, this plant has extreme potential for combining aesthetic and the preservation of local biodiversity in native landscaping. Unfortunately, rising temperatures have forced mountain-lovers even closer to the edge. I’ve had some enriching discussions with horticulturalists like Mike Heim up in Wisconsin, who have legitimate hopes to return Paxistima to their once-indigenous range to the northern U.S. where the climate is now mild enough for them to return.

If we fulfill our roles as fellow members and stewards of the ecosystem, maybe we can help the northern U.S. provide the same refuge for their long-lost plants and animals that the mountains of Appalachia did for northern wildlife during our last Ice Age.
