A day or two after my recent surgery, I was talking with Phil Douglas from Chicago Botanic Gardens. He was working on a PowerPoint about overused plants and asked if I could come up with any. So I Rolodexed through my files of photos to stir whatever those brain impulses are called that make you remember stuff and, surprisingly, came up with some plants. To the list, I added some rude commentary to amuse Phil. Which it did. And, now, I’m hoping, it might amuse you too. Sloppy, cruel, and mean-spirited? Sure. But I was on pain meds.
So what makes a plant overused? Well, that’s pretty easy. Take a combination of a person’s genetics and their life experiences, add a dash of their current mood, and, voila, an opinion. In some rare cases, there might even be an element of expertise, but many consider this to be much less necessary than once thought.
In this blog, the opinions are mine and, truth is, I’m not even sure I agree with half of what I wrote. That the vast majority of the below plants are growing in my yard, just goes to show you how little it should anger you if a favorite plant or two pops up. Or if the commentary isn’t fair.
So my twenty some odd overused plants are as follows.
Acer rubrum (Red Maple): The default shade tree of the very average, overworked, underpaid, and no longer interested landscaper.
Amsonia tabernaemontana (Bluestar): Why, when Amsonia hubricthii (Arkansas Bluestar) exists?
Angelonia: Neither a spiller, filler, nor thriller. Nevertheless, a plant you root for. You think it might achieve, you want it to, there’s a promising moment, and then it disappoints. A perennial (or annual?) “underachiever.”
Berberis thunbergii selections (Barberries): No matter which of its many colors and shapes, always boring. And one that revels in inflicting great pain.
Buxus (Boxwoods): The plant you turn to when you’re desperate and have no other options. Maybe in the next life there will be another choice for when you need a plant that is deer-proof, shade tolerant, evergreen, can grow anywhere, can be shaped like anything, and smells like cat pee.

Neep.
Calamagrostis ‘Karl Forster’ (Feather Reed Grass): Hate myself for even saying it, but it’s true. The Zebco 33 of grasses. But, like boxwood, so damned useful.
Cotinus: As seldom as these are planted, each new one is one more too many.
Crocosmia: Like that drunken boyfriend your crazy sister brought to your New Years Eve party, the life of the party until he puked on everyone’s coats that were piled on your bed. Can handle success for only so long. A time bomb. Great until it isn’t.

Crocosmia ‘Lucifer,’ before the thrill was gone.

Later that summer, having decided no one would notice if it went ahead and just let itself go.
Food Gardens: For those who go 100% in on things like perfecting a dozen yo-yo tricks, punk fashion, and disco.
Geranium Rozanne: Sure, it’s a good Geranium. So are all the others.
Any Hakonechloa except ‘Aureola’. (Hakone Grass): The vain attempt to improve on perfection continues.
Helleborus orientalis: I say this with great sadness.
Hosta: I say this with glee.

Just what the world needs, a hundred more Hosta introductions.
Hydrangea: Indeed, even the phrase “hydrangeas are overused” is overused.

So many hydrangea, so little planet.
Monarda: The feeling you get when you wake up and get that first good look at the “beautiful” person you hooked up with at the honkytonk just before closing time.
Metasequoia (Dawn Redwood): The hackneyed choice of plant geeks who can’t imagine they’d do anything hackneyed.
Narcissus (Daffodils): Just the big ones. They die like bad actors in silent B movies.
Pachysandra terminalis: Elected into the Groundcover Hall of Fame by the International Brotherhood of Weeds.
Pelargonium (Annual Geraniums): Divinely stunning flowers barely held aloft by sinfully ugly plants.

Forgot to mention, they need deadheading too.
Phlox subulata (Creeping Phlox): Only when used wrong, but it is always used wrong. Like an old 4-speed jalopy with a dead battery, always park it on a hill.
Fastigiate Quercus (Skinny Oaks): Why? The best thing about oaks is their unapologetic willingness to manspread.

Admittedly, an upright, uptight, fastigiate oak isn’t the worst thing, unless you want to take your lunch break in the shade!

Few things are as rewarding, however, as when an oak is allowed to truly express itself.
Rhododendron (In high pH settings): Man’s attempt to reorder God’s plan continues unabated. And unrewarded.
Roses: Although responsible for some of the planet’s most beautiful flowers, a difficult plant to include in beds and, like barberries or a bad cat, one that is more than happy to bite the hand that feeds it.
Rudbeckia ‘Goldstrum’ (Black-Eyed Susan): Even the laziest and most clueless of landscapers are getting bored with ‘Goldsturm.’ I think. Maybe I dreamt that. And nobody knows how to spell it.
Salix babylonica or whatever they’re calling the weeping willow: A coal-fired, steam-driven, industrial age disappointment machine for the home gardener.
Salvia nemerosa (and cultivars): A week or two of “okay” followed by months and months when you just look at it and shake your head.
Thuja plicata (Arborvitae): A good plant for screening but not the only good plant for screening.

Like a perp wearing a heavy coat at Walmart in summer raises the suspicions of store security, plantings designed to screen just make you really want to know what they’re trying to hide.
Ulmus americana (American Elm): Because we just can’t seem to learn our lesson about this species.
Over the top, oversized, double perennials: For those who, when riding the subway, can’t help but stare at that guy’s scar.
Lol, yeah, that bee balm really does get on my nerves, but the hummers like it, so there it stays, in its deliberately limited spot on one end of the butterfly garden. Sigh.
Thank you for the laughs for all these plants that might come in third place as runner up for congeniality.
But some of us who live in warm places would kill to grow Hakonechloa and Calamagrostis and even Hellebores well! Are you sure they are overused?
I’m not sure of anything! That said, Hakonechloa is not, I just liked ‘Aureola’ so much more than the others until two plant experts by the names of Paul Cappiello and Hans Hansen put their stamp of approval on ‘All Gold.’ I’m growing both. Still like ‘Aureola’ more, but with less confidence. Calamagrostis is planted a LOT!!! But it is so damned good. Beautiful, easy. Hellebores are borderline but a must because deer won’t touch them. Plus they’re evergreen, easy, bloom in winter, and the breeders are just making them so much better. I’ve got buds about to open on mine right now. If I had written the blog two weeks from now, Hellebores would have probably been left off.
Hilarious!! My favorite is the manspreading oaks, that about killed me.
Thanks, Mary! And to everyone who commented about the humor.
that made me laugh…and squirm I have 6 plants on the list in my UK garden.. I have been guilty of many a rudbeckia + buff grass combo with Rosanne at it’s feet but consider Rudbeckia deamii to be a hint more refined than Goldsturm,
Growing R.deamii with Geranium Patricia instead of Rozanne, I delude myself that by using
a slight variation of varieties I will lend a little originality to a plantng scheme….who am I kidding?
Actually …most people.
Would be curious if folks across the pond had a different perspective on this.
For the mid Atlantic region, I’d add euonymus “burning bush,” nandina, clematis virginiana and English ivy.
As a professional gardener in the mid-Atlantic, I totally agree with Linus. So weary of burning bush and nandina, and Buddleia davidii (butterfly bush) is closing in on runner-up.
I am constantly fighting the English ivy from my neighbor’s property, and I swear I can sometimes hear it whispering “resistance is futile; your garden will be assimilated” as I’m pulling, cutting, and creating inventive combinations of Bad Words.
Import some deer. Now that our local deer herd is out of control the invasive English ivy has been nearly eliminated from our property. Any time the ivy creeps over from my neighbor’s fenced yard the deer come by and gobble it up.
Thanks, Scott, that was funny
I hate that you wrote this and I didn’t. Excellent.
Sticking up for Thuja plicata however. In a world of lackluster Leylands, I am not hating that they are green, mean and on the scene in a big way. I’ll feel differently in ten years no doubt, when that’s all there is. – MW
I would love to see your list, Marianne! Please make this rant a series 🙂
I second that idea! Please make a list Marianne !
Great idea!
We’re lucky in that Leylands are considered not hardy here, although they probably are. Very rare to see one. And don’t hate, Marianne. You’ll write something funny sooner or later. LOL.
Funny! I’m at the point where I’ll take any plant if it will simply grow. My growing conditions? Four months of heavy rain followed by 3 months of drought. Ninety to 100 degrees in the summer with heavy humidity then crazy winter temps where it might be in the 70’s one week followed by -6 F the next….Not to mention a wicked 6-year infestation of citrus mites who have no known nemesis besides an insecticide. Give me the plants that are over-used if they will simply survive here.
Exactly what I have always thought about boxwood! Also autumn clematis.
I loved the list. Everything I want to add is probably included under oversized double perennials. Crepe myrtles and columnar-everything?
Loved this rant!!! Your descriptions were hilarious!!
Excellent! Please now follow with “Twenty Underused Plants.”
seconded
Good idea. I will give it a try.
Roses are surely overused, particularly now that Rose Rosette Virus is running rampant. I’d like to add Crape Myrtle to your list. Between murderous pruning, sooty mold and the Asian Bark Scale invasion, we can all do better, can’t we? Also, I would add the Entosporium leaf spot magnets-Indian Hawthorn and Red Tip Photinia.
I disagree about fastigiate oaks, at least in Texas. Fastigiate oaks seem a better option for small suburban gardens than the dreadful canker and bagworm-loaded Italian cypress, which should also be on a list. So many poor defenseless plants to trash, so little time. Well done, Scott. Hope you are feeling better, soon.
Hey – gardening in an area of heavy deer browse – a number of these plants are my go to plants. Would love to be able to grow other plant material, but I’m not into spending landscape dollars to feed the deer! Perhaps some of the overuse is due to deer??
Oh for sure! Yeah, an overabundance of deer is limiting the plant diversity in our landscapes more than any other factor.
Your crocosmia photo hit a little too close to home! I planted a bunch along my walkway this spring, got zero flowers, and was taunted for months by the sad grassy foliage flattened by wind. Maybe next year they’ll show up to the party.
Hostas, hydrangeas, and azaleas are EVERYWHERE in the suburbs around here! Like everyone hired the same landscaper. Same for spring bulb plantings: crayola colors. I am a hater of school bus yellow monstrosities but those split-cup and tazetta narcissus are a revelation, I tell you. Same feeling about the ubiquitous single tulips versus fringed, parrot, lily flowering and peony. Really I just dislike seeing so many garish mustard and ketchup garden flowers when there are so many other fun colors out there.
Anyone else also annoyed by seeing autumn joy sedum and daylilies everywhere, or is it just me? (And yes, I have some of each at my house)
The previous owners of my house had stuffed the entire property with tiger lilies, the common orange ‘ditch daylily’, and Rudbeckia ‘Goldsturm’. I bought the place in midwinter, so this was a…surprise. :-/ Five years on, I think I have finally eliminated 99% of them. The color orange has been permanently banned from my garden as a result. Clear yellow, yes. True red, yes. But I never want to set eyes on an orange flower again, lol
Can you really say no to Butterfly Weed? I had a client years ago who said “no orange” in her meadow, but I had a hard time envisioning a beautiful meadow with no butterfly weed. So although “Hello Yello” could be a good response, it was not easy to find, and I made a “bet” with her – I’ll plant 6 butterfly weed, and if you don’t like it I’ll replace it with something non-orange of your choice, no charge for planting. I also warned her that at least some of the butterflies it would attract would be orange! She took my bet and when the day of reckoning came the following season, she said that the butterfly weed was her favorite plant, and she had even grown fond of that particular shade of orange as a result!
The funniest thing I’ve read in a very long time. Thanks Scott. We love your sense of humor.
I agree with most everything on this list with the exception of Amsonia tabernaemontana (Bluestar)…that is one spectacular flower! Maybe it is overused in other parts of the country (?), but here in western New York, I’ve only seen one specimen of it in a local nursery’s outdoor plantings and it was gorgeous. I bought 2 small plants online ~2 years ago and waiting for those beautiful blue blooms
Honestly, I don’t think it is overused anywhere. I just like A. hubrichtii a lot more and feels it fills the same niche. Might have been a case where I liked the joke more than I liked the plant. The flowers between the two species aren’t so much different, but they are more striking on A. tabernaemontana. Both species are excellent garden plants.
I’m so happy reading this. Thank you. So much of this I wish I’d written or even cogently thought myself. Omg the barberry! Yes. And boxwood, I have made the boxwood mistake in my foundation planting and can get no one to discuss with me. I’m in Cincinnati – help? Haha.
Maybe we should form a support group? Or, possibly, a 12-step group? Maybe the only one that allows, or even actually encourages, alcohol consumption?
LOVED this rant! Didn’t recognise all of the plants….but enough of them! Sometimes I’ve fallen victim to a couple of them…..until I could find something else.
Rant on!
I also loved your “rant”. I once said that here in Michigan, it is the law that big box stores have to plant ‘Stella D’oro day lilies and the cultivars of honey locust. I truly wish people would stop planting barberry which is invading our woods and harboring ticks and burning bush also invading our woods. Why are commercial landscapers using the same old plants over and over and over!!??
They know no better, or aren’t asked for better? Or, ‘hey, it worked before…’
Kicking myself for forgetting ‘Stella D’oro!’
By all means, attach it as an addendum here! RIP Stella.
I’m so glad you chose two of the Three H’s (hosta, hydrangea and heuchera) for “most overused”. There are other shade plants, after all.
For across the pond, I would nominate verbena bonariensis, alliums and bananas/cannas. Perhaps some of our friends in the UK would like to add their suggestions?
I would have definitely added heuchera to this list. Here in the South (GA), it’s an annual, at best, succumbing to the ever-present heat and humidity, fueling much disappointment and regret as their carcasses pile up in compost heaps.
Most states do have an Invasive Species plant list. It is against the law for growers and landscapers to use or distribute these plants. Here in IN we have Euonymous f. and Euonymous a. on our list, in addition to a plethora of other bad plants. I foresee Callicarpa being added soon. Thanks, Scott for your spot-on column.
I like lace cape hydrangeas. And love my climbing one. I finally gave into the hydrangea frenzy and got 2 munchkins. How could I not? Name from Wizard of Oz! But year one they got a lot of mildew. They may be shovel pruned. And after much dithering over what ornamental shrub was the right one I got a smoke bush. Dang.
Scott, you did make me laugh, you also made me count the number of those plants that I grow. I would really like to see your list of 20 underused plants.
Fun rant Scott! Made me recall my Woody Ornamentals instructor from my college days in the 80’s. He had opinions on certain plants and one was bridalwreath spirea. Clear as day, I can still hear his somewhat high-pitched voice bemoaning the “most overuuuuuuuused” plant in the landscape industry. Funny, I just planted one last spring, and you really don’t see them much anymore. Other spireas, yes, and they, while pretty and durable, lean close to the edge of the overused cliff.
Thanks for the boxwood reminder. Just texted my son that it’s not cats preventing people from using the front entrance of his home. Wondering, however, if planting it will deter the porch pirates around here.
Funny–my crocosmia is the most commented on plant in my garden–none of my friends seem to have seen it before. I’m glad mine is in a pot–that is one messy-looking thing in the ground!
Eh oh. I’ve been bad.
I share so many of these! Crocosmia, monarda, and phlox made me snort a little too loudly sitting here in the airport reading this.
Great! Now I’m going to have to change up one of my beds that contains a barberry, rose bush and black eyed Susans.
I get it about hydrangeas. I have a gazillion hydrangeas in my back yard, mainly grown from cuttings, and just this past summer decided I had too many. Planning to dig up a few early spring and replace them with boxwood, of which, believe it or not, I only have one in my back yard. Need more structure. How did continus (smokebush) make the list? I have one that I hope to finally see the “smoke” this year. Had to learn not to trim it. Its tiny flowers have also gotten decimated by a late freeze, so no smoke. That said, I planted three more smaller continus this past fall and hope one reliably smokes. They really can be eye-catching.
I agree with every single one of these except for the Hellebores, and nearly died laughing too! 😀 The prior owners of my house had planted 12 of the plants on this list, PLUS a plethora of invasives as well (I am still stalking zombie Houttonyia cordata, seven years later…). I did keep the two purple-foliage cotinus, and the eight hydrangea are inoffensive enough. I would respectfully add the ubiquitous yellow threadleaf Chamaecyparis to the Overused list, though. (p.s. – Thank you for saving me from myself by posting the ‘Lucifer’ foliage shot!)
Scott, while you touched on many of my own pet over-peeves, you missed Stella d’Oro; the brash daylily of a thousand nightmares!
And, for that matter, gold-tipped junipers….Yuck!
I have to agree with those that mentioned Crape Myrtles and Stella d’Oro Daylilies.
As for roses, it’s the Knockout roses in particular that were way overused here in Texas, until they brought rose rosette disease with them to the party and wiped out not only themselves, but other much better roses in their disease ridden wake. We used to call them the begonias of roses. Which brings up begonias as bedding plants. It’s really hard to tell if their real or plastic!
Sorry, that was supposed to be …if they’re real or plastic. Wish I could edit!
Wait … what? Food gardens are overused? You want me to **buy** my fruits & veggies & herbs?!?!? I think not.
Great list, but I admit to being a big fan of Angelonia!
Does that mean that you couldn’t get your Metasequoia to grow? Ours is forty feet tall and wonderful…
Thanks for your amusing list! I do have a fond spot for Metasequoia, and can think of good excuses for a lot of the others too. I love Red Maple, and could spend hours looking at the leaf colors in fall – wild ones are as likely to be yellow, or mixed yellow-and-red, as red although the cultivated varieties always seem to be predictably red in the fall.
I am disappointed that another overused maple did not make your list, the Japanese Maple. On a past walk through our neighborhood, my wife and I counted 29 Japanese Maples in a 6 block long area. It was one of the first plants we removed when we bought our house, along with 6 rhodies so old I had to dig through layers of Mt St Helens ash to get them out (Mt St Helens erupted in 1980).
Driving around rural Willamette Valley, you see acres upon acres of Japanese Maples, waiting for some home builder, or designer with a copy of “Outdated Landscapes Quarterly” to snatch them up, and plop them in a yard, just slightly off the the side of the front door and walk.
Those are definitely overused but what can I say they are cheap so.
