growing hellebores and more, with barry glick
I’M OFTEN ASKED by frustrated gardeners how I managed to get my big old hellebore plants to grow so lustily—as if they are finicky, or difficult. To me they seem easy, but since reader questions persist, I decided to ask the guy with 6 acres of mature plants and decades of hellebore-breeding experience, Barry Glick of Sunshine Farm and Gardens. In my latest radio-show (transcript highlights are on the jump if you prefer to read, not listen) we also covered when to divide woodland wildflowers, and some deer-resistant recommendations for the shade garden, too.
Background: Barry Glick–a serious plantaholic who’s even a vegan and is sometimes also referred to in mock botanical Latin as the Glicksterus maximus–is a native of the Philadelphia area, and has been gardening since childhood. In 1972, he purchased 60 acres of a 3,650-foot-high mountaintop in Greenbrier County, West Virginia, that became Sunshine Farm and Gardens (which you can stroll though and shop from at sunfarm.com, and even go visit in real life by advance appointment). Barry’s a garden writer, a longtime lecturer and a major expert on plant propagation—but most of all I love how he was described in one magazine article I read recently:
“The Flower Child Who Became the Flower King.”

GROWING HELLEBORES, and multiplying them plus woodlanders like trillium and Virginia bluebells, was the topic of the latest edition of my weekly public-radio program with guest Barry Glick. Listen anywhere, anytime: Locally, in my Hudson Valley (NY)-Berkshires (MA)-Litchfield Hills (CT) region, “A Way to Garden” airs on Robin Hood Radio’s three stations on Monday at 8:30 AM Eastern, with a rerun at 8:30 Saturdays. It is available free on iTunes, the Stitcher app, or streaming from RobinHoodRadio.com or via its RSS feed. The April 29, 2013 show can be streamed here now. Robin Hood is the smallest NPR station in the nation; our garden show marks the start of its fourth year this month, and is syndicated via PRX.
snippets from my q&a with barry glick
IN THE TEXT BELOW, I harvested just the briefest details from conversations with Barry before, after and during the show taping, so be sure to listen in as well as read, for extra unexpected goodies. (Examples: the fact that a Number 8 “camel-hair” brush—which Barry uses for hand-pollination of hellebores—is actually made from squirrel fur. Or that the longest-lasting way to enjoy hellebore flowers is to cut them with about a quarter-inch of stalk left behind each bloom, and float them in a bowl of water, where they will last a couple of weeks.)
Q. I have grown hellebores—the ones I still call the orientalis hybrids—for about 15 years, and they have never missed a beat. Do people tell you they find them hard to grow, too, and ask you for the “secret”?
A. Hellebores are of the most idiot-proof plants in the world—and the only way I have been able to kill them is to plant them in puddles. If you’re in Florida or South Carolina and plant them in full sun and don’t water them, you’ll probably have problems, too, but they can grow in every state in the United States.
The ones that were called orientalis are actually Helleborus x hybridus—and draw on the complex genetics of about 19 species of hellebore that go into the mix. You can tell if you see ones with divided foliage that they may have Helleborus multifidus in their background, for example; viridis brings green flowers and of course purpureus beings purple. The species odorus, which sounds like it’s about fragrance, brings the yellow color. The hybrids are very easy to grow. They prefer rich, moist soil with good drainage, part to full shade.
Q. People always ask me when to divide hellebores–but I never have! What about you?
A. Hellebores don’t require division. I’ve had plants continue to flower for decades, and yes, maybe some plants after 30 or 35 years have shown a little dead in the middle. But mostly why divide them? By the way: The x hybridus types can live over 100 years.
If you want to share or multiply a specific plant, though, here’s what to do: Mark the particular plants you want to divide while they are flowering. Dig it up the following spring before flowering time—when the soil is just thawed. Wash the soil off so you can see where to make your divisions and make accurate cuts, using a sharp knife (I use a steak knife). Be sure to leave a couple of buds on each division.
I use an anti-shock transplant formula when I transplant (including Vitamin B1 and chelated iron and other ingredients). I also a high-Phosphorus fertilizer to encourage good rooting.
A. Yes, wait till they have their first set of true leaves to move.
A lot of people are disappointed that the seedlings, if they were self-pollinated by the parent plant, aren’t as vigorous—but you might get something interesting, if it was pollinated by another nearby plant.
Q. Compared to my hybrids that just get bigger and better year after year, staying in ever-widening clumps, Helleborus foetidus seems to move from one end of a bed to another as it wishes.
A. Helleborus foetidus is a shorter-lived perennial, and does indeed sow around the garden. There are many good selections within this species, with very different foliage. [Here’s ‘Frenchy,’ for instance, with very lacey leaves.]
A little background: foetidus is what’s called a caulescent hellebore (as is the species argutifolius). The acaulescent species (meaning “without a stem”) are those that contribute to the x hybridus types—all those other species we talked about.
Q. OK, let’s switch gears to other plants: When should I divide Virginia bluebells, Mertensia virginica? [Those are some, above, in Margaret’s front yard.]
A. Again—why divide them, as they will sow themselves around and make more, so it’s not a necessity to divide them (the way it is every few years with something like Heuchera). But if you need to propagate:
There are dormant buds all over the rhizome, so if you get a seven- or eight-year-old plant you can dig it up after flowering and after the seed drops. Cut up the rhizomes into a couple of pieces and plant them right away, and new buds will develop. Make sure the soil you put on top of it is loose.
But again: there’s really no reason to propagate, unless perhaps because you get a white-flowered one and want more of it. They’ll make a nice colony from seed themselves.
Q. What about deer? Are they a problem for you, and if so, what escapes their browsing?
A. The deer are so bad here, I say that they eat the paint off the barn. Want me to send you some?
But some things among many that they don’t eat: Mertensia, ferns, Primula japonica, Arisaema, Cimicifuga, Caulophyllum, Iris, Actaea, Delphinium, Paeonia, Thalictrum…
