I love gardening, but once September comes, I admit I’m ready to start packing things up and settling in for winter when I can get back to other things I enjoy like reading. That being the case, I tend to get an early start on doing things like tossing spent annuals and vegetables in the compost bin. While I’m doing that, I try to give away plants I’ve got too many of or don’t like anymore—I finally gave away that dreadful Vanilla Strawberry hydrangea (Hydrangea paniculata ‘Renhy’) I’ve been complaining about forever. Honestly, it’s a gorgeous plant in many ways, but the huge flower heads spend most of their time hanging down like the noggins of pouting children. Not. For. Me.
The other thing I do, which I’m sure looks kind of strange, is talk to my plants. Yes, it’s true that scientific studies have produced mixed results on whether talking to and/or playing music for plants has beneficial effects. But I don’t care. I enjoy crawling around on my hands and knees talking with my garden. ‘You don’t look very happy here, so how about we move you over there,” I’ll say to perennials that clearly aren’t blooming well because they need more sun now that the honey locust has gotten taller. Or, ‘I’m sorry, but I simply can’t let every single goatsbeard seedling grow up into a giant 4-foot-tall shrub, so you’ve just got to go.’ Neighbors joke: “Talking to yourself again?” I laugh, ha, ha, ha, knowing that no, I’m doing something so much weirder. I’m talking to (or maybe with) my plants.
I wouldn’t try to explain this to non-plant people, but I figure you wouldn’t be reading this blog if you didn’t love plants. So you probably understand what I mean when I say that I think of my gardens as a living creature, maybe even a friend in some ways. That being the case, when my husband, Mike, kindly offers to help with fall cleanup by using the hedge trimmer to more efficiently cut back plants, I cringe. “The hedge trimmer!” I can almost hear the plants scream. Still, I let him have at it on a couple of areas full of hostas. And then I just can’t bear it, so I go on working with my hand pruner, cutting to the ground leafy things while leaving perennials with seeds for the birds like black-eyed Susan, grey-headed coneflower, globe thistle, Joe Pye weed and golden rod.
As I move slowly from bed to bed in the fall, I take the time to do things like pull weeds along with stray maple and oak seedlings, dig up and toss out plants that are diseased and take note of sparse or overgrown spots. Like you probably do, I have a plant wish list and I’m always looking for an opportunity to squeeze something new in somewhere. Topping the list right now is Persicaria, not the variety with white flowers that you may think of as knotweed. I’d like to get ‘Firetail’, which is commonly known as mountain fleece. Hardy to our frigid Zone 4, ‘Firetail’ has pretty pink/red blooms that last from June to October. Plants are bushy, loved by butterflies, and grow 3 to 4 feet wide and tall in full sun to part shade. But I digress.
Let’s get back to plant whispering. Even if you don’t believe that talking to plants is helpful to them, it probably will be to you. Kneeling in the dirt, thanking plants for their brilliant fall leaves and interesting seedpods while apologizing for my role in their powdery mildew problem and other troubles, I feel calm and happy. Hours go by and it seems like only minutes. And all of the list making, teeth grinding, rush, rush, rush of life slips away as I enjoy the breeze, the sun on my face and watching the butterflies and bees taking the last sips of the season. Everyone should be so lucky to have a love they can get lost in.
Come on over gardener friends! It’s time once again to start sharing seeds at the Little Free Seed Library at my house. As many of you know from all my going on about it, the top shelf of our Little Free Library morphs into a place to share seeds every spring and fall. The library is located on the boulevard on the corner of 45th Street and Washburn Ave. S. in Linden Hills. (For more information and photos, check out this blog post from a couple of years ago.
I’ve already started putting seeds in there from my garden, but it would be great if many of you could bring some seeds too. If you do, please bring them in envelopes or baggies labeled with the name of the plant—one type of seed per container. If you would like to, and have the time, the label (or a piece of paper taped to the envelope or baggie) could include helpful tips like whether the seeds should be direct sown in fall or spring or started indoors before planting. That stuff isn’t necessary, though, if you just want to bring seeds, great!
When I started the Little Free Seed Library, I envisioned having all sorts of information inside about individual seeds and things like saving, starting and storing seeds. Three years on, I haven’t done that yet. I’m having trouble coming up with a way to make that stuff shareable without killing a zillion trees making handouts. I’m thinking about doing some laminated pages that people could look at without taking them. But if your brains are like mine, what you read probably won’t stick long.
Maybe people with smartphones could take pictures of the pages to read later? And yet, I hate to make things reliant on having a phone in your hand all the time. It’s not like I hate technology or anything, quite the opposite. But it makes me sad for the world to see so many people walking around this beautiful, amazing planet with their eyes glued to a stupid phone screen when they could be checking out a cool plant or bird, or maybe even talking with the real-live humans walking right beside them.
But I digress. Maybe laminated sheets are the way to go. If you have better ideas, I’d be grateful to hear them so please email me at my blog. If you come to get seeds and find some you’d like, there are small envelopes inside the box to put them in. You’ll also find pencils so you can label what you’re taking home. As I write this, the library so far includes these seeds: Royalty Purple Pod heirloom bush beans, Pot of Gold chard, Straight Eight heirloom cucumbers, blackberry lily, tropical milkweed (an annual milkweed), red swamp milkweed, black-eyed Susan, Queen Anne’s lace, hyacinth bean, white cleome, purple cleome, gray-headed coneflower and anise hyssop. There will be much more coming soon, and I leave seeds out for sharing until later in November when the whole library gets turned over to books once again.Read More»
Betty Ann Addison was preparing to say goodbye to her beloved, 16-acre nursery, Rice Creek Gardens, when I first met her in 2006. After 20 years, rising taxes and assessments had made running the park-like nursery she and her late husband, Charles, opened on the site of a former junkyard in Blaine a losing proposition. Her eyes were sad, but the joy she felt as she pointed out specific plants, many of which she and Charles had hybridized themselves, was obvious in the way she smiled, or sometimes laughed in that way she does, short, sweet, a cross between a squeal and a giggle. A person would have to be made of stone to not be made happy by that laugh. Hugging goodbye, she admitted that the move was hard, but things were going to be all right, she said, because “I will remember how blessed I’ve been, and I will go on living every moment and, well, isn’t that enough?”
Such a sentiment might sound hopelessly upbeat coming from someone else. But people who know Addison, who is now in her late 70s, know that she is the sort of person who has always lived every moment—and then some. Over lunch at her house in Feburary, she apologized for being tired, explaining that she had just gotten home from the gym and was feeling a bit discombobulated due to floor refinishing, kitchen updating and other house projects in the works. Still, in between bites of the chicken soup she’d made for us, she talked excitedly about the presentation she would soon be doing for the Potomac Valley Chapter of the North American Rock Garden Society in Bethesda, Maryland.
Addison is well known for her rock gardening expertise and has designed and built several public rock gardens including the Peace Garden at Lake Harriet in Minneapolis, as well as gardens in New York’s Central Park. “Rock gardening is the highest horticultural art because it incorporates so many thousands of wild and cultivated plants, combined with rocks, to make a landscape based on nature” she says. To illustrate, she tells the story of how her mother took up rock gardening in her 70s. “My mother passed away at 93 and she was a great gardener all her life. When she told me she wanted to try rock gardening, I built one for her and she said it was the best garden she ever had because every day there was something new to discover.”
For decades, Addison traveled the world with her mother, bringing home plants to try in their home gardens: hers in Minnesota and her mother’s on Long Island where Addison grew up. Sometimes the two of them brought back so many plants in their luggage, they had to send their clothes home in boxes. At a time when Minnesotans had few hardy plants to choose from, Addison’s trials and propagation of thousands of varieties of seeds from worldwide sources helped make the wider selection gardeners enjoy today possible.
Addison is a longtime propagator and breeder of hardy rhododendrons, including large-leaf rhododendrons, which were long thought to be ungrowable in this climate. Recently, she purchased an acre of land across the street from her house for testing rhododendrons and she’s looking forward to seeing some of her hybrid creations bloom this spring. On the day I visited, Addison was most concerned with the immediate need to transplant the hundreds of alpine cuttings growing in flats in the sunny, south-facing greenhouse she had built several years ago. Just a short set of stairs down from her living room, the greenhouse is the starting place for many of the plants she sells at her home-based nursery, Gardens of Rice Creek, in Fridley. The nursery is open every Saturday from 9 a.m. to 4 p.m. starting in May through Labor Day. And as she did at Rice Creek in Blaine, Addison offers an extraordinary selection of rare and unusual plants, including dwarf conifers, alpine and rock garden plants, as well as native wildflowers and rhododendrons.

Whew! I apologize for disappearing for so long. A family member has been ill for several months, and I haven’t had time to post. Things haven’t really calmed down, but I’m going to try to get back in the groove of writing more regularly so, here goes: Let’s talk about new plants for 2015. Or more specifically, new plants that can survive Minnesota’s horrifyingly cold, Zone 4 climate. For those of you who live where it’s even colder, I’ve got a few plants that are hardy to Zones 2 and 3. If you live in much warmer climates, you have the opposite problem. So you’ll want to check to see hot much heat the plants I’m talking about can take before you buy them.
You’re probably familiar with the U.S. Department of Agriculture’s Plant Hardiness Zones, which indicate the minimum temperatures in 11 areas across the country. By checking the USDA’s map, you can see whether a plant you’re considering can take your area’s minimum temperature. For example, in Zone 4b where I live, plants need to be hardy to at least -25° F to make it.
It’s always hard to choose just a few plants to highlight from the long list of new introductions each year. But here are some of my favorites. Before I go on, though, I want to remind you that if you are concerned about the effect of neonicotinoid pesticides on bees, you’ll need to check with sellers before you buy plants. Some retailers have stopped selling plants treated with “neonics” in response to studies suggesting that the pesticides harm bees, particularly honeybees. But this issue is still being sorted out and not everyone is on board. I’ll write more about what’s happening with neonics very soon, so without further ado, here are the plants.
Got shade? Try adding some Solomon’s seal ‘Tiger Stripes’ (Polygonatum falcatum) from Plant Delights Nursery to your garden. This variegated selection has pretty cream-colored highlights and grows to about 18 inches tall. Fruit clusters appear in the fall and plants are hardy to Zone 4. Plant Delights is located in Raleigh, N.C., and is known for offering unique plants that are hard to find elsewhere. Orders can be placed on their website.
I’ve never tried growing cobra lily (Chasmanthe Saturnus) but I’m going to try now. This South African native bulb offered by High Country Gardens blooms in mid-summer and is hardy to Zone 2. Spikes of fragrant, tubular orange flowers attract hummingbirds. Plants grow to between 3 and 4 feet tall and 2 feet wide and need full sun, which is 6 hours or more.
Toad lilies are great for our northern gardens because they bloom late in the season and look so tropical. Tricyrtis ‘Hatatogisa’ from Creek Hill Nursery is a lovely Japanese toad lily with orchid-like, purple-spotted flowers on long, arching stems. This plant is not really new, but it is being freshly promoted. Plants grow 18 to 24 inches tall and 12 inches wide and prefer part shade to full shade. Zone 4.
Looking for a tough, no-fuss rose that’s like no other? Head out to local garden centers and ask for Above and Beyond™ (Rosa ‘ZLEEltonStrack’), the newest rose from local breeder David Zlesak. David gave me this rose to test in my garden a couple of years ago, so I can attest to its hardiness and beauty. Introduced by Bailey Nurseries, Above and Beyond has apricot-colored flowers that open in mid- to late-spring and often rebloom throughout the season. Plants grow 10 to 14 feet tall and about 14 feet wide, which sounds ginormous, but you can easily prune them to be shrubs or climbers. I’ve got mine growing on a south-facing fence. Full sun. Zone 3.
I know they aren’t everyone’s cup of tea, but I like black plants. So I can’t resist suggesting Clematis recta ‘Lime Close’, also known as Serious Black™, a nod to Harry Potter fans everywhere. Unlike vining clematis, this new introduction from Walters Gardens offers dark-purple foliage that looks almost black and grows in clumps to about 6 feet tall. Foliage ages to green as the summer progresses and is topped with white flowers with slender petals. (Plan on supporting plants if they get too tall and floppy.) Walters doesn’t sell to the public, but you should be able to find this plant at garden centers. Full sun. Zone 4a.
If you like baptisia but wish plants wouldn’t flop over after they bloom in early summer, try Baptisia ‘Pink Truffles’ from Walters Gardens. One of several new varieties bred by Hans Hansen, this false indigo is compact at just 2 ½ feet tall and 3 feet wide and offers delicate, pink flowers. Plants are drought tolerant once they are established and should be grown in full sun to part shade. Zone 4.
And last but certainly not least, let me point out a really striking grass from Walters Gardens. (Again, this should be available at local garden centers.) Schizachyrium scoparium ‘Twilight Zone’ is a little bluestem that is now widely available after a limited release last year. In addition to its columnar form, this ornamental grass offers silver/purple highlights. Grows to 4 feet tall and 2 feet wide. Full sun. Zone 3.
Most of these plants should be available at garden centers this season, but in some cases you can order directly from the website I’ve provided.
My dad told all kinds of fantastical stories when I was a kid, and I believed all of them. To this day, I can’t drive past a “Watch For Falling Rock” sign without thinking about the Native American hero named Falling Rock, who disappeared in the desert and was never seen again. If I had kids, I would tell them stories about dragonflies, something about how a magic spell of some sort turned big-eyed, prehistoric beasts into delicate winged creatures that really like water.
I’m not sure exactly when dragonflies started inhabiting our gardens. But these days, they are as nearly as ubiquitous as the butterflies and bees used to be just a handful of years ago. Perched on plants or flitting around from one place to another, the brightly colored creatures are as unreal as seahorses and endlessly interesting to watch. They’re also beneficial carnivores, capable of eating hundreds of mosquitos in a single day.
Attracting dragonflies to your yard is easier than you might think. The most crucial thing to provide is a water source, and even the simplest water feature will do. It’s also important to include a diverse mix of plants, trees and shrubs that can provide cover; offer places to mate and lay eggs; and draw in insects that hungry dragonflies can munch on. But before I go into more detail on how to invite them, here is a bit more that you might not know about these interesting creatures.
What Are Dragonflies?
Dragonflies really do have prehistoric roots. More than 300 million years ago, they were among the first winged insects to evolve. While today’s dragonflies have wingspans that range from about 2 to 5 inches, some dragonfly fossils have been found to have wingspans of more than two feet. That is frightening enough. But the thought becomes absolutely terrifying when you consider that the aquatic insects belong to the insect order Odonata, which is Greek for “toothed one,” referring to dragonflies’ serrated teeth. When they eat, dragonflies most often snatch flying insects in midair, tear them into bits, smush the bits into a ball and chow down.
Look closely and you’ll notice that dragonflies can look quite different from one another. That’s because the insect order Odonata also includes damselflies. Generally smaller than dragonflies, damselflies have slim bodies and eyes that are separated and somewhat protruding rather than flat and centered on their heads.
It’s easiest to tell the two relatives apart by looking at their wings when they’re resting on something, which damselflies do more often than dragonflies. Dragonflies rest with their wings flat and parallel to the ground while damselflies hold their wings pressed together over their backs, like a butterfly. An estimated 5,000 to 6,000 dragonfly and damselfly species have been identified worldwide, and about 140 species can be found in Minnesota. Go here to learn more and see photos of some our state’s dragonflies and damselflies. To hone your dragonfly identification skills, check out Stokes Beginner’s Guide to Dragonflies by Blair Nikula, Jackie Sones and Donald and Lillian Stokes.
Most dragonflies and damselflies need water throughout their entire lifecycle. Every species has its own requirements for things like water quality and the types of aquatic vegetation on which they prefer to lay their eggs—though they also lay eggs in the water. In their larval stages, when they are known as nymphs, the insects spend months, sometimes years, living underwater before emerging as adults.
Adding a pond to your landscape is sure to bring on the dragonflies. If you have the space and resources to do that, choose a spot that gets at least five hours of full sun in an area that’s somewhat sheltered from winds, especially from the north. If possible, create a pond with varied depths so there are shallow areas near the edges and a depth of at least two feet in the center. Larvae will be safer from predators like raccoons in the deeper parts of the pond. Because fish feed on nymphs and eggs, it’s best not to include them in ponds where you’d like to encourage dragonflies to breed.
Stock the pond with water-loving plants, including submerged plants for females to lay eggs on and tall emergent plants for nymphs to climb up when they’re ready to slough off their last larval exoskeleton and transform into flying adults. Adults will also use emergent plants when they stop to perch and scan for potential mates or food sources. There are several submerged plants (also called oxygenator plants) to choose from, but a few good options are: anacharis (Egeria densa), fanwort (Cabomba canadensis), hornwort (Ceratophyllum demersum) and wild celery (Vallisneria sp.).
A few emergent plants to consider are: corkscrew rush (Juncus effuses), dwarf horsetail (Equisetum scirpoides),dwarf papyrus (Cyperus isocladus), blue flag iris (Iris versicolor) and parrot’s feather (Myriophyllum aquatic).
More Water Ideas
Don’t have room for or want a pond? How about a small rain garden or bog garden? Or maybe a water container garden made from a half whiskey barrel, galvanized tub or anything else that’s handy and can hold water will work well. Use the same plants mentioned above to create your container water garden, which should be located in a sunny spot. For detailed instructions on creating container water gardens, see my article on the subject in the May/June 2013 issue of Northern Gardener.
If all of that sounds like too much work, take the easy route and just add a water feature like a simple fountain. We created a few small fountains for our yard using inexpensive pond pump kits that we bought on sale at a local big-box store combined with a galvanized tub or livestock troughs. Be aware that pond kits don’t always come with filtration systems that are adequate enough to handle outdoor debris. So you may want to do what we did and buy an additional filter box that will filter the water before it enters the pump.
Place your container where you want it, put the pump in the bottom of the container and use a rock or brick to hold the cord in place. Next, drape the cord over the edge of the container and use another rock to secure it on the ground before directing it toward a power source. Fill the tub with water, flip the switch and your gurgling fountain becomes a magnet for dragonflies and damselflies. Adding plants will hasten their appearance, but it isn’t necessary. Basically, if you have a water feature, they will come.
Plants for Every Purpose
The plants that you choose for your landscape are nearly as important as the water you provide. Dragons and damsels will use ornamental grasses, shrubs and trees planted within a few feet of a water source as perching sites and to help them hide from predators like birds and spiders. Flat rocks placed around the edge of a pond, water container or fountain will become places to rest and bask in the sun. And although midges and mosquitos make up the bulk of their diet, you’ll see more of these meat-eating beauties if you plant flowering perennials that entice beetles, wasps, moths and other small flying insects that become their prey. (Yes that does include some bees and butterflies.)
Bee balm (Monarda didyma), black-eyed Susan (Rudbeckia hirta), black snakeroot (Actea racemosa), blanket flower (Gaillardia), cardinal flower (Lobelia cardinalis), catmint (Nepeta), coneflower (Echinacea), Culver’s root (Veronicastrum virginicum), golden Alexander (Zizia aurea), goldenrod (Solidago canadensis), Helenium, Joe-pye weed (Eupatorium fistulosum), Liatris, Phlox, Russian sage (Perovskia atriplicifolia), speedwell (Veronica), Salvia, swamp milkweed (Asclepias incarnate) and yarrow (Achillea filipendula) are all great choices.
Ensuring A Safe Haven
Like bees and butterflies, dragonfly and damselfly populations around the world are in decline in part due to pesticides. Studies have shown that the widely used neonicotinoid pesticide, imidacloprid, is particularly toxic to the aquatic insects, as well as other water-dwelling species. So if you want to attract dragons and damsels, do your best to steer clear of pesticides and other chemicals that may be harmful. And if you’ve got one of those bug zapper things to help control mosquitos, put it away because it will zap the dragonflies too. Don’t worry. In a very short time, those hungry little carnivores will thank you by keeping mosquitos in check all on their own.
A version of this article appeared in the 2014 September/October issue of Northern Gardener magazine.
For me, the words “neighborhood sweep” bring to mind the busting up of meth labs and prostitute rings, or maybe less dramatically, a big litter cleanup day in which everybody pitches in. But on Friday, we got a letter from the City of Minneapolis Department of Regulatory Services Housing Inspection Services Division advising us that we were being cited in response to a NEIGHBORHOOD SWEEP (yes, all caps) for the “conditions” of the gardens along the sidewalk on one side of our house. Failing to correct the NUISANCE CONDITIONS (perhaps they should be cited for errant use of all caps) could, they advised, result in the city arranging to do the job one way or another at some future date.
What were those nuisance conditions, you ask? Fall flowers, mostly New England asters and a couple of varieties of golden rod, but I admit that a few black-eyed Susan’s and blackberry lilies also ran afoul of the law by encroaching here and there on the public sidewalk. Growing primarily in our boulevard gardens and heavy with seeds, in the case of the lilies, and blooms in the case of the rest of the flowers, the plants were indeed lolling out onto the walkway an inch or two in a few places.
And there was one rogue aster leaning out at an awkward angle at about fourth-grader height. We also have a river birch in our yard and its wispy branches, which we routinely trim, are at least six feet above the sidewalk. The rule, we now know, is seven feet.
Even with all of this mayhem and out-of-control bramble, two people could have handily pushed a couple of shopping carts or strollers side by side down the walk and been brushed only slightly, if at all, by plants. There are no fat shrubs hogging space or heavy, low-hanging tree limbs threatening to bump heads or poke eyes out. So while it is understandable that in a civilized society we need to have rules about things like keeping public sidewalks clear, this citation seemed outside the bounds of reasonableness to me.
Our neighbors can attest to the fact that we spend a lot of time pulling weeds, pruning and trimming plants, and just generally working hard to keep our yard looking good and out of people’s way. We’ve never had anyone complain about problems getting down the sidewalk. Honestly, people walking by often go out of their way to stop and tell us how much they appreciate the peaceful pocket of nature we’ve cultivated in the city.
Families stop to watch the bees, butterflies and dragonflies flitting from plant to plant. We answer all sorts of gardening questions, and have learned a lot from other gardeners too. People as far away as several blocks often stop to tell us that we’ve inspired them to start their own gardens, and many of us share seeds and plants.
It pained us to cut down flowers that bees and birds were actively feeding on last weekend because rules are rules. And I couldn’t help wondering how many other gardeners had been cited and were experiencing the same thing. So I want to ask whoever is listening, what can we do as a city to rethink rules that require a level of obedience from nature that simply isn’t possible while ensuring that our sidewalks remain safe and traversable? For every person whose day is made brighter by urban gardens, and every creature, especially pollinators, that seeks those gardens out for habitat, it’s a question we need to consider.
