trilliums in trouble, with mt. cuba’s amy highland

Flowering shrubs can grace your garden, adding color, interest and sometimes fragrance to the home landscape. For the biggest, showiest flowers, you’ll also need to take into account the sun exposure of the garden site. But never fear, there are flowering shrubs for landscaping that like sun and others that like shade.

Lee’s tips for growing pawpaw or American persimmon couldn’t make it sound more appealing, or simple:“Plant it, water it, and keep weeds and deer away for a couple of years, and then do nothing,” he says. No fancy pruning (like those apples crave), no particular pests–and a big, juicy harvest. More details on how to choose which variety to grow are included in the highlights from the April 29, 2013 edition of my public-radio show and podcast, transcribed 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

Adam and I talked about not just the Japanese types, but also other garden-sized maples for adding interest in every season and garden situation–in pots or the high shade of woodland gardens, to full-sun locations.my maple q&a with adam wheelerQ. When I was at Broken Arrow recently, there were many choice things to look at—but I kept noticing the maples you offer, particularly. How many do you grow?A. In the collection at the nursery, I suspect we have 150 or 200 different maples, and really that’s the tip of the iceberg with this genus.Q. There are a lot of native A

On my public-radio show, Arboretum director Mark Weathington took me through the years-long process of “discovering” new plants. Plus, Mark highlighted some Arboretum specialties that may belong in your garden, including standout redbuds and mahonias, and the lesser-known evergreen shrub Illicium, and even showy native dogwoods selected to withstand increasingly saline soils in tricky coastal areas.What’s now called the J.C. Raulston Arboretum at North Carolina State University is where I met my first Cephalotaxus–a near-lookalike to our common evergreen yews but excitingly deer-resistant. And then a moment later I met another one–this time a columnar form–an

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-

Let me admit: I have a soft spot for old apples, and the massive, century-plus-old trees I’m blessed to cohabitate with deliver loads of imperfect but delicious fruit with the occasional soft spot—or at least various marks of character.The venerable trees have taught me an appreciation of botanical history, more than some modern idea of perfection. That lesson was underscored in 1999, when I visited Seed Savers in Decorah, Iowa, where about 10 years earlier founder Kent Whealy had begun the orchard, each tree bearing a name, and a backstory, I’d never heard before. Apples such as the ones up top (clockwise, from top left): ‘Franklin,’ ‘May Queen,’ ‘Woodard,’ and ‘Blue Pearmain.’Dan Bu

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.

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
