WE GARDENERS ALL KNOW the expertise of the lack of crops that don’t make it for one cause or one other, from a tomato felled by illness in a too-humid summer time to a venerable outdated tree taken out by a nasty winter storm.
There are losses yearly, irrespective of how knowledgeable you might be, however a few of them actually stand out in reminiscence, indelible.
Vegetation now we have liked and misplaced, however by no means forgotten (like my Aesculus pavia or crimson buckeye, above): That’s our matter this time, with my pal, Ken Druse. You all know Ken, who gardens in New Jersey and is the writer of a powerful 20 backyard books.
Learn alongside as you take heed to the July 24, 2023 version of my public-radio present and podcast utilizing the participant beneath. You may subscribe to all future editions on Apple Podcasts (iTunes) or Spotify or Stitcher (and browse my archive of podcasts right here).
crops we’ve misplaced (and miss), with ken druse
Margaret Roach: Hello, Ken. Misplaced something these days [laughter]? I needed to ask.
Ken Druse: You proposed this as an thought a couple of week in the past, and I may hardly bear in mind those which are lacking.
Margaret: I do know.
Ken: I imply, I can bear in mind the particular ones. Conservatively, I’ve misplaced 50 % of the herbaceous crops, normally within the first yr. However I feel it’s rather more than that. I take a look at footage from 15 years in the past, I don’t even know what these crops are.
Margaret: You stated I introduced this up per week or no matter in the past, and the reason is that in August, you and I are going to do a free webinar about actually particular crops—identical to a biggest hits and issues we suggest for various functions and so forth. We wished to say that, shout that out.
However within the means of determining that webinar and the curriculum, so to talk, for that webinar, we ended up discovering ourselves speaking a little bit bit about, “Oh yeah, do not forget that such-and-such?” [Laughter.]
Right here we’re with a little bit teaser. Ought to we complain first for 30 seconds in regards to the climate? What number of inches of rain have you ever had within the final week? I’ve had 5.2.
Ken: I’m very near that. However the warmth, and now mosquitoes, which we not often have mosquitoes right here. We’ve got mosquitoes like a business for OFF! once they used to point out the man’s arm getting into a field. That’s what it’s like. It’s unbelievable.
Margaret: We’re fortunate, as a result of neither considered one of us for the time being has damaging flood or injury to our homes or something like that. But it surely’s very dramatic, very terrifying, and studying the headlines is much more terrifying. A shout-out to all of you who’re attempting to farm or have had injury or no matter.
Ken: To not point out orange sky earlier than that.
Margaret: Smoke will get in your eyes, proper? Yeah.
So: Vegetation which have gone earlier than. I like music [laughter]. I get lyrics caught in my head, and I’ve a kind of folks with the earworm drawback of a tune going by my head on a regular basis. This matter jogs my memory, I’ve to inform you, Ken, of a Willie Nelson-Julio Iglesias duet. I don’t know in case you bear in mind it, “To All The Ladies I’ve Cherished Earlier than.”
“To all the ladies I’ve liked earlier than/who traveled out and in my door/I’m glad they got here alongside/I dedicate this track/to all the ladies I’ve liked earlier than.”
However that’s sort of like what was on my thoughts after I introduced this as much as you. Who have you ever liked and misplaced? Who do you wish to shout out first?
Ken: Nicely, I suppose to let me a little bit bit off the hook, I’m going to shout out first some crops that it wasn’t my fault [laughter]. It’s most likely by no means my fault.
Margaret: O.Okay. Who’re we going to scapegoat for this?
Ken: One of many tallest bushes on this property was an ash tree, inexperienced ash, I feel [above, background center]. I’d heard about emerald ash borer. Everybody was speaking about it, and eventually it got here right here. This ash was over 100 ft tall and over 100 years outdated. It misplaced department by department, and it needed to come down. That was sort of icky.
Margaret: Wow. Yeah.
Ken: I’ve a lot bother doing that, arboricide.
Margaret: Letting go?
Ken: Or murdering. Yeah, letting go.
Margaret: Taking it and saying, “O.Okay., I quit. I admit defeat. It is a misplaced. I’ve misplaced this particular person.”
Ken: Particularly when it’s over 100 years outdated. Though I can weed, however that’s about it [laughter]. I can transfer a plant if vital.
Margaret: I used to be at a pal’s backyard the opposite day and he requested me to come back over and take a look at an outdated contorted hazel or filbert, no matter we name it, European hazelnut or filbert. Corylus…what’s it… avellana ‘Contorta,’ I feel, you say?
Ken: Proper. Harry Lauder’s strolling stick.
Margaret: Precisely. He had this actually outdated… I imply, after I say actually outdated, I feel it was 25 years outdated and it hadn’t leafed out nicely this yr. He questioned if it was the spongy moths. I stated, “No. It’s not that it’s been defoliated, it’s that it didn’t leaf out.” I regarded carefully and I stated, “I feel it’s a goner. I feel it’s nearly carried out.”
He was identical to, “Aaaah,” as a result of it’s simply this sculpture, as a result of it’s so outdated, it’s wonderful. Thankfully, that one is not going to must be taken down instantly, however may most likely be a good-looking sculpture for fairly numerous years.
Ken: For Clematis to develop on or one thing.
Margaret: Precisely. Precisely. Anyway, however yeah.
Ken: They do have an issue at the moment. The Corylus have some sort of illness.
Margaret: Sure, they do. There’s sure varieties which are extra resistant than others and so forth.
Ken: However typically it’s aesthetic and I do know I ought to do it. I bear in mind after we first moved right here, John Trexler got here and checked out all of the woody crops, the late John Trexler, who was a woody plant knowledgeable. There was a blue spruce that had hardly any department besides on the prime, and it was very tall. John stated, “It is best to do away with that.” I wouldn’t hear of it for over 20 years when it lastly didn’t have any branches. It actually was an eyesore, and an enormous drawback visually and design clever within the backyard. He was proper from the beginning.
Margaret: Usually what the frequent title that folks use for blue spruces is they are saying Colorado blue spruce. That’s one of many frequent names for it. The Colorado offers you a touch about that plant, which is that it’s a plant that grows in a mountain setting. It’s an higher elevation… Not on the very prime of mountains, however you realize what I imply. Nevertheless many generations in the past we turned it right into a cultivated plant, or tried to show it right into a cooperative cultivated plant, as a result of it’s fairly fast-growing, it’s enticing. it offers you a number of oomph in your backyard.
We began utilizing it throughout in a number of areas of the nation, besides its lifespan exterior its pure setting is, in case you’re fortunate, 20, 25, perhaps 30 years, however probably not. You outgrow it in case you keep in your own home on your entire grownup life. Quite a lot of instances it’s not even such as you had been speaking a couple of pest that got here and obtained your ash. Generally it’s simply that we actually shouldn’t be attempting to develop a few of these crops the way in which we’re attempting to develop them, proper?
Ken: Generally it’s the soil, the alkalinity or the acidity, unsuitable place. Generally it’s shade, typically it’s shade. And typically it’s due to I suppose I may say optimism [laughter]. When anyone says, a grower says Zone 7A, and I feel, ooh, that’s nearly the identical as 6B or 6A. Possibly even it’s there for 3 years earlier than the chilly lastly will get it. However now with the blue spruce, the way in which issues get a lot hotter right here than they did 25 years in the past.
Margaret: It’s accelerating what I used to be simply speaking about. I used to be speaking to some plant pathologists from Purdue just lately, Purdue College within the Midwest, they usually had been saying it’s simply folks nonetheless come into backyard facilities asking for it, however good backyard facilities shouldn’t promote it and don’t promote it as a result of they know that it’s probably not proper for that local weather or the Northeast or no matter.
Ken: Round right here, they promote it as a shrub a couple of foot tall.
Margaret: Proper.
Ken: After which it turns into an enormous tree.
Margaret: But it surely’s superb in case you say, hey, it is a short-lived sort of factor.
Anyway, all proper, so that you misplaced an ash just lately. I’m attempting to assume if I misplaced one thing just lately. I used to be pondering extra again to some… I imply, I bear in mind watching in horror, it was my first shut private expertise with the yellow-bellied sapsucker woodpecker, which is a local woodpecker and a beautiful chook and all the things, and has this very methodical, very grid-like geometric sample of drilling into thin-barked crops.
Amongst ornamentals, it loves magnolias. It made mincemeat out of a yellow magnolia. Talking of bark, I had this pine, a Chinese language pine species, Pinus bungeana. What do they name it? I can’t bear in mind the something-bark pine. Anyway.
Ken: Lacebark?
Margaret: Yeah, lacebark. Thanks. It has like a camouflage sample. Beautiful, beautiful bark. After all, what does the chook resolve to do as a result of it’s a skinny bark additionally? It decides to make a large number out of it and weaken the tree. These actually ooze once they’re opened up, when grids of sap wells are opened up, and it croaked.
I might like to have that plant as a result of it was not solely four-season for its coniferous foliage, nevertheless it was four-season for its stunning trunk. It was only a great plant, Pinus bungeana. Such as you stated, lacebark pine. However I don’t dare. I simply don’t dare. However that’s one which I like to recommend to folks. [Lacebark pine, above, at Brooklyn Botanic Garden; photo from Wikimedia Commons.]
Ken: Did it die or did it snap or one thing?
Margaret: No, it simply obtained an increasing number of…
Ken: It bled to demise.
Margaret: Yeah, it actually nearly did. It simply obtained weaker and weaker. It actually relies upon. I’ve a magnolia on the opposite facet of the home, a really outdated magnolia, that was already outdated when the yellow-bellied sapsuckers began being as fascinated about my place [laughter] as they’re. It’s obtained plenty of sap wells in it and it’s completely superb. It’s a Loebner hybrid, ‘Ballerina,’ is the title of it, a hybrid early flowering white magnolia.
It’s humorous to take a look at it particularly within the winter as a result of all you see is the sap wells, the grids of sap wells on the trunk [laughter], however the chook by no means kills it as a result of I feel it was far sufficient alongside and well-enough established. I feel perhaps typically in the event that they get to the plant early sufficient, like with that Pinus bungeana, it by no means had an opportunity to actually…
Ken: Outgrow the injury.
Margaret: Yeah, I feel so. I feel so. That was an awesome plant although. Extremely suggest it.
Ken: I like that plant. There’s one at Wave Hill that’s spectacular that you simply’ve most likely seen. One yr anyone carved a coronary heart within the bark and it was anyone liked anyone. I used to be so outraged. However three years later, it had healed fully so that you simply couldn’t see it, which is humorous. As a result of in case you try this to a beech tree, it’s there perpetually. However the lacebark really healed over. Yours was too younger, too skinny.
Margaret: Yeah, to actually tolerate it.
Ken: After I lose one thing, in fact, I wish to know why. We had a ‘Forest Pansy’ Cercis canadensis [above], which is redbud, and the ‘Forest Pansy’ has purple leaves. It’s very enticing. The one which we grew obtained big. One yr Hurricane Irene and Tropical Storm Lee, the tree was underwater, only for a few days and it died. That made me assume that Cercis, in fact, needs higher drainage, however I’ve sandy soil, nevertheless it doesn’t need… It wants that oxygen. A pal of mine misplaced hers, and I noticed that there was a sprinkler head proper subsequent to it.
She was really drowning this plant. We had seven hemlocks on this property after we got here right here. We solely have one now. There was a big one [below] that had been attacked by woolly adelgid. It was sort of weak. After which in that very same hurricane, when it was below 4 ft of water only for a few days, that’s all it took, as a result of hemlocks, too, have very shallow roots, they usually want air. You don’t take into consideration bushes needing air. You concentrate on them needing water, in fact, however they do want oxygen on the roots.
Margaret: Proper. You may actually suffocate them. You talked about the japanese redbud, Cercis canadensis, and that purple-leafed cultivar, ‘Forest Pansy.’ There’s a bunch of dark-leafed ones, totally different cultivars. I used to be just lately talking to the director of a public backyard on an outdated property in Villanova, Pennsylvania, known as Stoneleigh. On the oldest property home, they espalier a number of native woody crops and vines as nicely.
One of many ones that they like to espalier—which I hadn’t seen carried out, however I imply, I suppose it’s apparent—is issues like ‘Forest Pansy,’ the dark-leafed Japanese redbuds. They minimize out a number of the branches and make a fan sort of factor. It’s simply actually dramatic with these stunning, what are they, heart-shaped, would you say, the leaves. They’re stunning. There’s one which’s a tricolor leaf. Have you ever seen that one, ‘Carolina Sweetheart’?
Ken: Oh, is that the one which’s yellow and orange?
Margaret: There’s a sunset-y wanting one, too, however there’s one with pink in it as nicely, pink and purple. Oh my goodness, it’s beautiful.
Ken: There’s too many. I’ve ‘Silver Cloud.’ I don’t know in case you’ve ever seen that.
Margaret: No. No.
Ken: That has nearly pure white foliage with little touches of pink. I believed that’s going to get broken within the solar. I planted it within the shade, and it actually limped alongside for about three years. I used to be in North Carolina and I noticed that tree rising in a garden in North Carolina and it’s full solar. I dug it up and moved it to a sunnier spot and it’s implausible. It doesn’t burn.
Margaret: The redbuds are nice, and a number of the cultivars with the colourful leaves provide you with a little bit additional oomph so far as the…
Ken: And there are weeping ones. It’s humorous how that occurs.
Margaret: What else? Another ones that you simply wish to shout out that you simply nonetheless bear in mind from-
Ken: Nicely, years in the past, and it’s not that a few years, I used to be waxing poetic about actually most likely the showstopper on this backyard was a sort of Cornus kousa, a Korean dogwood, variegated, known as ‘Wolf Eyes’ [above]. We had been speaking about it and also you stated, “Oh, there’s an issue with ‘Wolf Eyes.’” The Cornus kousa, we all the time thought develop these as a result of they don’t get illnesses like Cornus florida, the Japanese dogwood. It was superb. I believed, oh, what does she know.
Margaret: As a result of she’s an fool. My pal Margaret, she’s like such an fool. It’s unbelievable [laughter].
Ken: I feel the following yr it had so many flowers. Generally when a plant makes a number of fruit or a number of flowers, it’s sort of like a last-gasp. That was one yr it had a number of flowers, and the following yr the branches began to die again. After which the following yr it died. I’d had it for lengthy sufficient that it had the great bark. Speak about camouflage, the bark was stunning. This tree was so beautiful and it died.
Margaret: As you stated, Cornus florida, the native flowering dogwood, is vulnerable to anthracnose particularly in our local weather, within the Northeast and in locations the place there’s humid circumstances that put it on the market. A lot of the kousas are usually not, however ‘Wolf Eyes,’ and there’s like three I feel which are particularly vulnerable to it.
Ken: Now you inform me.
Margaret: I feel ‘Autumn Rose,’ ‘Moonbeam,’ and ‘Wolf Eyes’ or one thing. I had learn that as a result of I had had the plant, pondering the identical factor, years earlier than and had the identical expertise the place it declined with anthracnose.
Ken: I obtained it on the Commerce Secrets and techniques plant sale years and years and yr in the past.
Margaret: The plant sale in Connecticut. Proper, proper, proper. I like the Cornus kousas. I solely have two, however I might be heartbroken if I misplaced them, as a result of they’re so floriferous, proper? I imply, they’re so showy.
Ken: Later than the floridas. The Cornus florida is over. After which in between are these great Rutgers hybrids that to this point, knock wooden, knock dogwood, don’t get illnesses, they usually’re fairly fast-growing. We’ve got ‘Stellar Pink,’ I feel it’s known as, and ‘Celestial Shadow.’ Largely they’ve Rutgers names as a result of they’re from Rutgers.
Margaret: Rutgers College, the breeding program.
Ken: However they take one of the best of each species.
Margaret: One plant I actually miss, one woody plant I actually miss that I had for therefore a few years, and it was sort of a rarity, an actual oddity after I first obtained it, and I don’t even bear in mind, I obtained a tiny little plant from someplace, perhaps it was from Forest Farm Nursery by mail order out West or one thing like that, Aesculus pavia, the crimson buckeye [above, and top of page]. It’s sort of like an enormous shrub, small tree kind of a creature. Possibly you may get to twenty ft technically, however I haven’t seen that too typically. It’s like Southeastern, down into Florida, like North Carolina right down to Florida native, I imply. Its vary goes over to love in the course of Texas and over to Illinois.
So it’s not native right here, nevertheless it’s a Native American plant to these locations that I simply talked about. It has these unbelievable panicles, these stems with flowers coming off them in all instructions—if you realize any of the Aesculus, you realize that look—of deep crimson. They’re simply unbelievable crops. I like that little tree. It simply went kaboom, goodbye. It didn’t decline. It simply croaked. And that was my expertise.
That’s one I’d wish to have once more, and I don’t know why I haven’t made room to place one other one in someplace. However that jogs my memory, that very same expertise was what was most likely, gosh, considered one of my most beloved of all that I had for a lot of, a few years, a Korean maple, not a Japanese maple, however a Korean maple, Acer pseudosieboldianum. It was proper if you got here into the place. You opened the gate and also you got here within the driveway. It was proper there in your proper, this large assertion.
It was good naked. It was like a Japanese-mapley look naked, nevertheless it was particularly stunning in leaf. The autumn shade [below] was unmatched by something I’ve ever seen, as Japanese maples additionally are usually. One yr, perhaps 5, six, seven years in the past, it was completely superb. It obtained its nice fall shade, and many others. It went to sleep for the winter and it by no means awoke.
These are those that not solely make me unhappy, however unhinge me in the way in which that that’s most likely a soil-borne factor like Verticillium or one thing, one thing within the soil. It’s simply mysterious. The trickiest half then is you’ll be able to’t go purchase one other one and stick it in that gap. You couldn’t danger it.
Ken: That’s what I used to be pondering. That’s a superb rule of thumb. If you happen to get one other one, don’t plant it in the identical place.
Margaret: One other plant pathologist advised me, really another person at Purdue advised me not way back, in case you see a kind of sudden-death issues with the woody plant and you believe you studied it may be Verticillium, plant an eggplant there [laughter].
Ken: You imply as a check case?
Margaret: Sure, as a result of eggplants are extraordinarily inclined to Verticillium wilt and use that as your check. Now, you’ll be able to clearly ship plant samples to the pathology lab and so forth, however isn’t that humorous? The eggplant check [laughter]. Any others do you wish to share?
Ken: The nicest Aesculus pavia, which is without doubt one of the dad and mom of the crimson horse-chestnut, that I ever noticed was in Virginia at Williamsburg. They’d stunning ones. However we’ve had one right here for years. It’s fairly small, nevertheless it blooms.
However I used to be pondering with the Cercis, for instance, the redbuds, they develop from Texas into Canada. Not the identical; there’s multiple species. However that one species, canadensis, does develop all alongside the East Coast. Generally you must assume the place did this ‘Forest Pansy’ originate?
Margaret: This particular person, the genetics of this particular person.
Ken: Though we’re shopping for it, or this selection.
Margaret: What ecotype inside that? what I imply?
Ken: Proper. That’s why perhaps if it got here from the mountains, it wanted to develop on rock or alkaline or one thing. That’s a technique. Now we’re speaking about tree forensics and backyard plant forensics. What killed my plant, that great poem by Geoffrey Charlesworth.
Margaret: Sure, sure, sure. I feel you continue to have one plant that I miss very a lot, lo these a few years later, that I lastly misplaced. It’s a rambling rose, and I don’t even understand how you actually pronounce its title, however I say ‘Veilchenblau.’ It’s a historic rose, 1909 introduction. It’s like a semi-double. It’s a rambler. I feel on the time, and even now, I feel it’s billed because the closest to blue {that a} rose will get. [Flower detail above from Wikipedia.]
Ken: It’s the bluest rose.
Margaret: I ultimately misplaced that. I really assume that was when a tree fell adjoining to it and that entire space obtained trashed. I feel that was not a illness sort of a factor. You’ve got ‘Veilchenblau’?
Ken: Sure, in a horrible place, nevertheless it’s alive and it blooms as a result of it’s an enormous plant. It may be an enormous plant if it’s not useless. It does have these violet flowers. I don’t assume they’re aromatic, nevertheless it’s actually stunning.
Margaret: Is there one other one you wish to inform? I’ve another that I may, however I may skip it.
Ken: No, you may, however you’re breaking my coronary heart right here [laughter].
Margaret: Oh, I’m sorry.
Ken: No, that’s O.Okay. I’m fascinated with the hemlocks which are gone and there’s one left. The ashes, in fact, and the spruces. There was Norway spruce, they’re gone; the blue spruce is gone. It’s arduous to recollect those which are gone, until you see a stump.
Margaret: Or take a look at outdated pictures typically. That’s what I discover jogs my memory of one thing.
Ken: Yeah. I’m curious, what’s the one you had been going to say?
Margaret: Nicely, I used to be going to say, you had been speaking earlier than about moist spot can kill one thing. Clematis actually hate moist ft, particularly within the winter. I had two yellow Clematis, which isn’t a typical shade in Clematis. One was tangutica. It was the range known as ‘Invoice MacKenzie’ [above] within the tangutica group. It’s obtained nearly these purple-brown facilities, the stamens, or this beautiful contrasting shade to the vivid yellow, like canary yellow. It’s only a great plant. I had it in a spot that I developed a kind of winter moist spots of roof runoff after which a puddle. I didn’t assist it. what I imply? I didn’t notice it was getting right into a low spot for the winter, and that drowned.
The opposite yellow one was a paler yellow. And by the way in which, I may get one other ‘Invoice Mackenzie’ and I ought to, that’s accessible. However the different one was a paler yellow that I knew was chiisanensis ‘Lemon Bells,’ nevertheless it’s been modified. The title is now Clematis koreana or one thing ‘Lemon Bells’ [below]. But it surely was like pale yellow flushed with pink and the stems, the vine was nearly like a blackish-purple. Oh my goodness, it was probably the most scrumptious, stunning factor.
I don’t have any thought what occurred to it, and that one’s actually arduous to get. That’s typically the worst factor, is when it’s nearly not replaceable or you must go down a ready checklist and hope to “get one sometime in case you’re fortunate” sort of factor.
Ken: You jogged my memory with the drowning and the way typically if in a moist spot, then it turns to ice. The roots can’t take up any oxygen or something.
Margaret: Precisely.
Ken: And it does kill it. However I grew a ‘Woman Banks’ rose, which isn’t hardy the place I’m in New Jersey, in Brooklyn. It grew up in the back of the home and it grew to nearly 4 tales tall. Individuals would come when it was in bloom with a thousand flowers, sadly not aromatic, little double butter-yellow flowers. Even Marco stated, “You may’t develop that right here.” They might stand there taking a look at that shrub and say, “You may’t develop that right here.” I feel Judy Zuk stated that, too.
Margaret: We’re speaking Marco Stufano, previously of Wave Hill, and Judy Zuk, previously of Brooklyn Botanic Backyard. We’ve, in fact, run out of time, however I’m pondering now longingly of that rose on the again of your Brooklyn house.
Ken: I’m rising the white double one now, which is nice, and it’s alive.
Margaret: Good. Nicely, thanks for an additional enjoyable dialog.
Ken: Yeah, that was one thing.
Margaret: See you at our free webinar that we’re going to do August 10.
Ken: Nice.
