New York Ironweed (Vernonia noveboracensis) has always been a volunteer wildflower on my floodplain. That’s the native habitat for this passionately purple wildflower. This year when we built a new pollinator flower bed, I had an excuse to plant more ironweed. New York Ironweed tops out between five to eight feet, but I decided to try a taller species to plant behind some of the other flowers I added. I chose Vernonia gigantea ‘Purple Pillar.’
Purple Pillar is supposed to reach heights of nine to ten feet, but in its first year for me, it achieved about half that — not bad at all for a late-spring-planted newbie in a new flower bed. I planted two specimens; both bloomed profusely, attracting a wide array of native pollinators, including these:
Ironweed species native to my region of the southeastern US piedmont all bloom in late summer/early fall. Purple Pillars can theoretically bloom through October, but mine shifted to seed production by late September. I’m hoping that next year the plants will be larger and bloom even longer.
I didn’t do any formal record-keeping, but from my photos and my observations, it seemed to me that my ironweeds attracted a wider diversity of insects/arachnids than my enormously floriferous Joe Pye Weeds. Between these two species, I think just about every butterfly in my neighborhood found my new pollinator bed.
Although this wildflower naturally occurs in moist places, it is highly adaptable both in its moisture and light requirements. It will thrive in a typical flower bed. I pampered all my plants in my new pollinator bed with extra water this year, because they were just getting established. Next year, I’m hoping they will grow larger with no additional water from me — unless we are plagued with significant drought, of course. I’m certainly not going to let these beauties die from extreme weather conditions if I can prevent it.
At a distance or up close, covered in butterflies or standing solo, ironweeds are a native perennial wildflower that every piedmont gardener should grow. If you don’t have this species in your garden yet, plan on adding some next spring. You — and your local pollinators — will be glad you did.
I know that many of my readers are, like me, dedicated long-time gardeners. We speak fair botanical Latin. We know what we mean when we say “part sun,” or “drought-resistant.”
But we also see plenty of neighborhoods full of houses landscaped with lots of fescue lawns, perhaps a sad little tree or two stuck in the middle of the green expanse, and some evergreen shrubs planted along house foundations, often pruned into geometric shapes not found in nature. Many of you old-pro gardeners may not realize it, but living in many of those regimented-looking, nearly biologically sterile neighborhoods are folks who would like to do more with their yards. They want butterflies and birds, but they haven’t got any idea how to attract them. And they don’t know where to start.
That’s actually why I started writing this blog back in January 2011. And it’s why I volunteer at the plant help desk at the NC Botanical Garden. I enjoy sharing what I know, trying to make that information accessible to folks new to the southeast (They are legion.), or just new to gardening.
I’ve been telling my readers about the NC Botanical Garden’s upcoming Fall Plant Sale for several weeks now. It’s the weekend after this coming one, by the way. That sale can be a bit overwhelming to some folks, because an enormous array of native species is offered for sale — table after table of pots of various sizes, all organized alphabetically by their Latin names. There are signs for every species with photos of mature plants and their flowers, information on how big they will grow, what growing conditions they need. But, still, it can be hard to know where to begin.
Thus, I am delighted to share with you that, this year, the folks at the NC Botanical Garden will be making it a bit easier for less experienced gardeners to pick out plants suitable for their yards with two new features. First, I am working with the staff to develop lists of suggested plants for certain situations. For example, at a table on Members’ Night, you’ll be able to pick up a list of suggested natives — all for sale that evening — suited for a sunny pollinator garden to provide blooms throughout the growing season. This list won’t contain all the possible options; we intend these lists to be starting points. With the pollinator garden list in hand, you can find a plant on the list, read more about it on the sign on the table, and decide if it is something you want to add to your garden. There will be lists of plants that like moisture (as for rain gardens or pond or stream banks) and ones for dry areas too. Again, these lists won’t be exhaustive, but they will give you a place to start.
The staff at the NC Botanical Garden has come up with one other new feature that any gardener trying to add native food sources for our pollinator and other insects will appreciate. As Douglas Tallamy wrote in his now-classic Bringing Nature Home, without the native trees, shrubs, wildflowers, and grasses that insects eat during their larval stages, their adult stages will not be available to pollinate our crops, and birds and other animals will die if they don’t have these immature and/or adult insects to eat. An entomologist by profession, Dr. Tallamy compiled lists of which native insects rely on which native plant species. Many insects only eat one species of plant. If it disappears, so do they.
That’s why I think it’s wonderful that the staff of the NC Botanical Garden has created the sign above to inform customers about how many insect species rely on particular plant species. These numbers come from Dr. Tallamy’s research, so you won’t see these signs for every plant at the sale. But when you do see one, you’ll know that the plant in question plays a key role in our local native food chain. When you buy a native blueberry plant, you’ll get a beautiful addition to your landscape that will produce berries and lovely fall color; but you’ll also be increasing available food sources for native insects, birds, and other wildlife — a win-win all around!
I hope I’ll see many of you at the plant sale on Sept. 23-24. The staff at the NC Botanical Garden has worked hard to contextualize their offerings to make it easy for you to figure out what will work best for your landscape. Please come out and pick up some plants to feed your local natives — and to support the only public garden in piedmont North Carolina with the central mission of educating folks about the beauty and importance of native plants.
My corner of southeastern US Piedmont has been blessed with steady — but not excessive — rainfall all summer this year. I cannot remember a growing season like this one. All the plants — weeds included — have responded with enthusiasm. And so have the animals, including most every native pollinator — and pollinator predator — that one expects to see in my region.
This growing season will be remembered by me as the summer of the Eastern Tiger Swallowtails. Never have more of these beauties adorned every blooming plant in my yard, animating the landscape with their slow, drifting flights from flower to flower, often bumping into me as I stood nearby, camera in hand, trying to capture their wondrous abundance. Many flowers have attracted these butterflies, but of all my plants, my healthy stand of native wildflower, Joe Pye Weed (Eutrochium purpureum), deserves special recognition for its power to attract, not only Eastern Tiger Swallowtails, but also just about every other native pollinator in the neighborhood.
Truly, it has been a perpetual pollinator party on the Joe Pye Weed since it started blooming over a month ago. And it is still blooming! I cannot recommend this native wildflower enough for anyone planting — or adding to — a pollinator garden bed. It’s a can’t-miss pollinator magnet. For those of you interested in planting for native birds, Joe Pye Weed is an excellent choice. Insect-eating birds will delight in harvesting a few pollinators as they work Joe’s flowers. And when the pink flower heads ripen to tan-brown seed heads, seed-eating birds like our native Goldfinches will happily dine on the seeds.
This native wildflower naturally occurs along creeks and wetland areas, but it adapts with no difficulty to garden beds, as long as you water it a bit during dry spells. My clump has grown larger every year without much supplemental water at all. The species can top out at about 6 feet, which might be a bit tall for some landscapes, but it is easy to find shorter cultivars at local nurseries that stop at three or four feet, and I’ve found that if you cut the growing stalks of the tall form by about half in early summer, they will bloom at about four feet instead of six, making them less floppy after summer thunderstorms.
Joe Pye Weed is also not picky about the amount of sunlight it needs. It will bloom a bit more prolifically in full sun, but I’ve got stands of it in shady spots in my yard, and the flowers on those plants are almost as abundant — and also enjoyed by numerous pollinators.
I confess I have spent perhaps too much time this summer sitting in front of the Joe Pye Weed in my new pollinator bed (more about that soon). The constant dance of pollinators drifting in and out, the drama of predators snagging unwary insects, the kaleidoscopic colors — it’s all very hypnotic — and soothing.
We are fast approaching the optimal season for planting perennials, shrubs, and trees in our region. Fall is for planting, as we say in these parts, because the air is cool but not icy, so roots can establish thoroughly before plants go into winter sleep, enhancing their vigor and drought resistance when the spring growing season arrives. If you are planning to plant — or add to — a pollinator- and/or bird-friendly garden this fall, be sure that Joe Pye Weed is part of your plan, whether it be the straight species, or one of the many fine cultivars available.
There’s no better place to purchase all the native plants you need for your upcoming fall-planting projects than at the Fall Plant Sale at the North Carolina Botanical Garden in Chapel Hill. This year, Members’ Night is Friday, September 23, and the sale is open to the general public on Saturday morning, September 24. Not only do members get first dibs on the vast array of natives offered at this sale, they also get a 10% discount on their purchases. And for you procrastinators out there, you can join at the door on Members’ Night. I encourage all the native plant lovers within driving distance of Chapel Hill to put this don’t-miss plant-buying party on your calendars now. And be sure to pick up some Joe Pye Weed, so your pollinators can party on it next growing season.
