standout native hydrangeas, with mt. cuba’s sam hoadley

Tom Stearns is founder of High Mowing Organic Seeds in Vermont, with more than 20 years specializing in breeding, selecting and marketing of organic varieties. From microgreens indoors to baby-leaf to mini-heads and up to full-sized heads in the garden, we talked about timing, spacing and making lettuce happy—even which types hold up best in the heat (and ways to help all lettuce do better when summer arrives).Read along as you listen to the Jan. 14, 2019 edition of my public-radio show and podcast using the player below.

If you said Heuchera, you’re right. Perhaps you’re going to reshuffle some shady beds this spring, and know that Heuchera, with their great foliage, can help make garden pictures work–but wonder which ones, and how best to use them. I invited George Coombs, trial garden manager at the must-visit Mt. Cuba Center in Delaware, with 50 acres of native-plant display gardens and 500 acres of natural land, back to the radio show to help make the best choices and grow them to perfection.George knows from Heuchera, having trialed 83 varieties side by side (the exhaustive results are in this pdf). “I say to people, ‘I’m doing Consumer Reports for plants,'” he explains. Though there are countless varieties on the market, many are duplicative in appearance or just not distinctive. “I can honestly say that when it

Brushwood Nursery, aka gardenvines [dot] com, was founded in 1998 in Kennett Square, Pennsylvania, out of a Lord and Burnham greenhouse Dan rented for $5 a year plus upkeep. (Such a deal!) Dan, a University of Delaware horticulture graduate, used to teach at nearby Longwood Gardens and worked with Conard-Pyle, where he got fluent in the propagation of Clematis, which most nurseries call “a nuisance crop,” he says, with their particular trimming schedules and rambunctious intertwining tendencies.Enter a business opportunity: a high dollar-per-square-foot greenhouse crop, and one that not everyone is good at–enter Brushwood. He started selling vines over eBay, eventually launching his own website, and recently outgrew the climate and space in Pennsylvania and moved to Athens, Georgia.The Brushwood collection now numbers more than 500 climbers, with Clematis as the main event—including ‘Omoshiro,’ top photo, which may be the first large-flowered one I ever buy (it’s more than 7 inches across, and fragrant). There are climbing roses, jasmines, passionflowers and more–but let Dan tell

THE FLYER PIQUED MY INTEREST: Dan Benarcik, part of the creative team at Chanticleer Garden in Wayne, Pennsylvania (a must visit!), would be lecturing nearby about “The Art & Craft of the Garden,” and how to personalize a garden using artistic elements, found artifacts, and ornamental containers. I quickly got a ticket—you can, too, for the June 16 event, including garden tours and a garden market, in Spencertown, New York—but also asked Dan to share some of his ideas and images (including the bromeliad-artemisia- urn-and-melianthus moment at Chanticleer, above) with us, no matter whether we can attend. A Q&A with this enormously talented plantsman and garden artist.

A little about Michael:“That’s Michael Dodge,” I say, when I show people around the fall garden, as we pass a large group of show-offy, yellow-fruited Viburnum I enjoy all fall into winter. V. dilatatum ‘Michael Dodge’ is truly a standout plant.But the original Michael Dodge, the one that great shrub was named to honor, is a well-

Kate Spring, and her husband, Edge Fuentes, founded Good Heart Farmstead in Vermont in 2013, which serves up to 100 customers each season who subscribe to their CSA share program. Their farm is a hybrid business structure called an L3C, a low-profit, limited-liability company, where part of the mission is to support Vermonters in need of food access.Kate’s also a writer and the only person I know with her very own brand new yurt, which I couldn’t wait to hear about after having seen it be constructed on her Instagram.Read along as you listen to the December 14, 2020 edition of my public-radio show and podcast using the player below.

In the early 1990s, when I was working on a book called “The Natural Habitat Garden” with my friend Ken Druse, we traveled the country interviewing native-plant enthusiasts and photographing their gardens. One memorable stop was the home of Mrs. Lammot du Pont Copeland, outside Wilmington, which today is the botanic garden called Mt. Cuba Center, with more than 50 acres of display gardens on more than 500 acres of natural land.I’d never seen native terrestrial orchids before, or the vivid red and yellow wildflower called Spigelia marilandica anywhere, and that day I learned that some discerning and forward-thinking experts such as Mt. Cuba’s first horticulture director, the great Dick Lighty, were already busy selecting “better” forms of native plants for garden use–a trend that has accelerated and become one of the hottest areas of contemp

We’ve talked before on the show about your past trials of other native plants like Baptisia and Heuchera—and native plants are the mission of Mt. Cuba, which is both a garden for visiting and a research center, right?A. Mt. Cuba Center is actually a former du Pont family estate, the Copeland family estate, and they left their estate to become a public garden. What kind of sets us apart from others in the area is that we focus on native plants. We broadly define our nativity region as the Eastern United States.We do a lot of work promoting plants in a display capacity in the gardens itself, and then we also do research like what I do, trying to help

Jeff is Director of Grounds and Coordinator of Horticulture at Scott and Swarthmore, where among the extensive and diverse plantings is a whole Tree Peony Garden area, one of the first collections established after Scott was founded in 1929 and now including more than 80 varieties of tree peonies. He is also vice-president of the Mid-Atlantic Peony Society.Why consider these plants? Tree peonies are deer-resistant, extremely cold-tolerant, long-lived and really don’t require a lot of complicated pruning. And oh, those flowers (that’s one of Jeff’s favorites, ‘Nike,’ up top.).Read along as you listen to the April 10, 2107 edition of my public-radio show and podcast using the player below.

First, some background: Great Lakes Worm Watch is a citizen-science outreach organization, working to map the state of the earthworms—and the habitats they’re living in.“We want to know where earthworms are across the landscape,” says Ryan—and that means even beyond the Great Lakes area, where the project began.  (There is a Canada Worm Watch, too, for those across the border; researchers at the University of Vermont, at the Cary Institute in Millbrook, New York, and elsewhere are likewise studying earthworm invasion.)Individuals, schools or garden groups can sign on help collect data on what worms are fou

George Coombs managed the Trial Gardens at Mt. Cuba Center native plant garden and research facility in Delaware. In past conversations, George–who in 2019 was promoted to Mt. Cuba’s Director of Horticulture–has helped me make our way through the daunting selections of Heuchera, Monarda, and Baptisia. George and the trial garden team spent three years evaluating 94 different sun-loving selections of Phlox for eye and butterfly appeal and mildew resistance, plus 43 shade-garden choices, too.  Read along as you listen to the February 26, 2018 edition of my public-radio show and podcast using the player below.

Entomologist Doug Tallamy and his wife have spent 14 years coaxing back to life 10 acres of what had been farmland for nearly four centuries: achieving more diversity by adding layers to its once-flat botanical architecture. Today 54 species of birds nest on their Delaware property, and acorns the couple planted have become 20-foot trees–so many that now editing is required.Tallamy, professor in the Department of Entomology and Wildlife Ecology at the University of Delaware-Newark, has been called the “guru of the habitat gardening movement.” He is co-author with Rick Darke of a recent book, “The Livin
