Cynthia Wood wrote a nice article about the Quarry Gardens that covers four pages of the March issue of Virginia Gardener [http://www.statebystategardening.com/va/]. Such media exposure over the past few years has helped bring visitors and groups to find enjoyment, learning, and inspiration at the Quarry Gardens—so we are grateful to both writer and magazine. Virginia Gardener‘s website doesn’t include articles, so here are a few quotes and photos from it.
“…a new kind of botanical garden that would showcase the unique ecosystems and plants that have evolved around the old soapstone quarries on the property.”
This view from the trail across the old access road into the South Quarry pool includesa group of locally native Arrow-wood viburnums that are among the nearly 100 species that have been added to the 450 legacy plant species found here.]
“…a botanical garden that could serve as a resource for individuals interested in learning about native plants and how to use them in their home gardens.”
These masses of goldenrods, planted near the Visitor Center and quarry viewing platform, are among 14 species of goldenrod here to tempt gardeners.
“The visitor center is a repurposed Quonset hut with an added entrance that gives the building a sense of purpose and ties it to the environment.”
Cynthia took this photo last fall, soon after the Center for Urban Habitats team finished planting in the Visitor Center’s demonstration garden. This season, we expect visitors will be greeted by a much more vivid expression of flora.
“Many of the plants in the Quarry Gardens attract pollinators, such as this Eastern tiger swallowtail.”
This native Moss phlox will be creeping over the rock walls and luring swallowtails again in just a matter of weeks.
“Massive Giant’s Stairs lead down to a lush gallery of spring ephemerals and ferns in a Piedmont basic oak-hickory forest.”
And here we are—Armand, Bernice (with trail guide badges), and Skyla—all wearing goofy smiles, standing by the stairs.
If you are interested in seeing the whole article, we posted this blog entry a few days early to give you a chance to get the Virginia Gardener March issue, which will remain on sale until about the third week of March.

The appetites of northern Europe’s reindeer and North America’s caribou give Cladonia rangiferina its economic value—and its common name: Reindeer lichen.
Reindeer lichens grow in northern temperate forests, boreal forests, and even tundra. Here at The Quarry Gardens, C. rangiferina forms a silvery carpet over the north-facing slope above the South Quarry pool, where only a thin layer of soil covers the rock—and where there is very little competition.
Although its highly branched growth pattern resembles moss—and it is sometimes called Reindeer moss—Reindeer lichen is truly a lichen, a composite organism of fungi and green algae. The relationship is symbiotic: The fungi provides the structure, nutrients, and protection that allow the algae to photosynthesize and produce sugars for the fungi. (Although genetically unrelated, lichens and mosses often appear together in the lousy soils they both tolerate.)
Reindeer lichens are generally latecomers to disturbed forests that have not been burned or logged in at least 40 years. This side of the South Quarry was undisturbed for at least 40 years before we put the trail through, and possibly for much longer, as the quarry access road did not extend so far to the south.
The clumps grow slowly, producing tiny new branches just one-eighth to one-quarter of an inch long per year. The age of a clump can be estimated by counting back through the major branchings along a stem. After about 20 years, the lower parts begin to decompose, so counting can be difficult. Mature clumps—degraded at the center like this one—are often estimated to be 100 years old, or more.
Soft and spongy when wet, brittle and fragile when dry, if overgrazed, burned, or trampled, the lichens may take decades to return. That’s why this slope is designated as a conservation area. Fortunately, unlike reindeer, our local charismatic megafauna have shown no taste for Cladonia rangiferina.
In the same family as Cladonia rangiferina is this Cladonia asahinae, with the apt common name Pixie cup lichen. More widely distributed globally—it also occurs in the southernmost part of South America and in the Antarctic—this cold-hardy lichen has been found growing on mosses near the North Quarry pool.

Our featured image for this issue of the blog is of Ezra and Theo Staengl stalking butterflies. the brothers, aged 14 and 10, live in nearby Afton and are avid plantsmen and birders who, because they are homeschooled, are able to travel widely in pursuit of their interests. Ezra writes a blog and Theo contributes many of the photos that appear on it. If your appetite for outdoor exploration and discovery is greater than your time or energy can support, you might try a bit of vicarious adventuring with Ezra and Theo via the blog Birds and Buds. A recent post featured the Quarry Gardens: https://birdsandbuds.com/2017/12/21/quarry-gardens-ecosystem-modeling-under-geological-constraints/ We’ve seen Great horned owls at the Quarry Gardens, but Ezra photographed this one on a nest in Lancaster County PA last March.
The young men are intrepid. The past year’s entries, for example, trace a coastal birding expedition complicated by an approaching snowstorm, a visit to a rare and endangered Loudon County ecosystem, arduous treks through places with such names as Grimm Prairie, Difficult Creek, Dismal Swamp, and Iceberg Lake Trail, among many others—all in search of rare birds, butterflies and flowers almost never personally observed by those with less spirit. Although not particularly rare, this Zebulon skipper was photographed by Ezra in nearby Orange. It is one of 40 species of butterfly documented so far at Quarry Gardens.
Speaking of plants, Ezra said: “I think I like plants so much because they form the most basic, tangible foundations for nature. Their seemingly never-ending diversity is all around us and is so rarely noticed. They create and define different ecological communities, which host all the other life forms. I also like plants because the rich, multi-species reactions and relationships that define these plant communities are still so poorly understood.” If you think he seems young to be so focused, note that he also plays soccer, and violin in the Evans Orchestra, one of the Youth Orchestras of Central Virginia.
Birds and Buds includes a link to Ezra Peregrine on flickr, a stunning portfolio of hundreds of images that document the brothers’ sightings of plants, birds, butterflies, odonates (dragonflies and damselflies), and other animals throughout Virginia, around the U.S., and on travels to other countries.
The final photos are of Ezra’s Nashville Warbler photographed in northwest Ohio, and his Green jay photographed in south Texas.
