CAN A HISTORIC formal house grow to be the house to a forward-thinking panorama of native vegetation? The group at Stoneleigh, a five-year-old public backyard on an previous property in Villanova, Pa., says the reply is an emphatic sure.
And their horticultural experiments appear to show that’s true.
Its director, Ethan Kauffman, and I spoke about how he and his colleagues are reinterpreting the grand previous panorama with a natives-only ethos that was handed all the way down to them by the nonprofit known as Pure Lands that conserved the place.
Two-dozen sorts of native vines now climb the majestic century-old stone pergola at Stoneleigh, and space-defining hedges of white pine and American arborvitae, or dwarf Magnolia grandiflora, are amongst these redefining the 42-acre panorama. There’s a number of different classes for house gardeners, too.

natives in a proper setting, with ethan kauffman
Margaret Roach: Yeah, so we did a “New York Instances” column collectively, and that was enjoyable. And studying about what you’re doing down there at Stoneleigh, actually reinterpreting this historic house. And as I mentioned within the introduction, with this native mandate. It’s very, very thrilling, and I feel it actually does apply to house gardeners who’re questioning, sure, however how do I take advantage of these vegetation? I knew how you can use hostas and Astilbe; now what do I do [laughter]? So how lengthy have you ever been there and the way lengthy has this been open?
Ethan Kauffman: I’ve been at Stoneleigh for about seven years. It’s onerous to consider, however I began in 2016 in the direction of the tip, and the backyard has been open 5 years. So we’ve been within the panorama for all the seven years, actually. And it’s been such a joyful expertise. This place was attractive after we acquired right here, and we had this unbelievable alternative, as you mentioned, to remodel it to a backyard that not solely serves as a spot of rest and rejuvenation for our visitors, but additionally helps all our native wildlife and ecology and get to have enjoyable doing it.
Margaret: And it’s free. It’s open to the general public aside from, I feel, Thanksgiving and Christmas, and what? On Tuesdays to Sundays, is that proper? Nevertheless it’s free. It’s freed from cost, which is simply unbelievable. So welcoming, actually.
Ethan: It’s. And I feel while you stroll into Stoneleigh, you’re feeling that welcoming spirit, that form of snug, accessible vitality. And perhaps it’s the massive bushes. Now we have so many truly previous, large bushes right here, and you are feeling, I don’t know, I really feel form of the sense of security and luxury beneath their boughs. So it’s actually a particular place.
Margaret: So this was greater than a century of historical past earlier than you all acquired there. I imply, this was an property on the Philadelphia Foremost Line. And inform us a bit bit about what you inherited. As a result of there’s this mansion, simply there’s some remnants, yeah?
Ethan: Oh, completely. And for millennia, in fact, this was cultivated by the Lenape tribe. After which when it was colonized by Europeans, it was agricultural until concerning the 1870s. And this space of western suburbs of Philadelphia known as the Foremost Line has all these estates that had been constructed in the course of the nation place period, from 1870 to 1930, and Stoneleigh’s a kind of grand previous estates. And it was a very magnificent and is a powerful place. It was designed largely by the Olmsted Brothers, from about 1906 to 1955. So we actually had some nice, nice landscapes to work with.
Margaret: And what I keep in mind after we first talked, after we did the “New York Instances” interview and we had been simply attending to know one another, you advised me that while you acquired there, there have been seven acres of pachysandra and I feel 14 of mown garden on this 42-acre property [laughter]. In order that’s not very ecological or that that’s fairly the other of what your mission was, and is.
Ethan: Yeah, Margaret, I’m not kidding. Once I first walked in there and I noticed that pachysandra, I mentioned, “Oh my gosh.” And turf. And within the first, I feel, month, there have been simply two of us on the time, and we noticed this pachysandra; we had been simply so able to do away with it. So we didn’t have any gear, so we rented this mini-excavator and the 2 of us took turns and we ripped out about an acre of it, which really turned our parking zone. So it was very satisfying that first elimination of pachysandra. We’re nonetheless chipping away. I can promise we’ll be at it for a very long time, however I feel that’s what makes this place accessible too. Now we have a small group, it’s not taking place instantly. And so our visitors and the those who are available our neighborhood can see this transformation happen earlier than their eyes. And it’s very relatable to what they’re doing at house.
Margaret: And with all that garden, you didn’t do away with it with the excavator such as you did with that one acre of the pachysandra, you’re treating it otherwise, or managing it otherwise.
Ethan: Garden is such a giant a part of American tradition, and everyone knows that it’s troublesome on our sources, particularly water, and it’s not notably productive for wildlife. So with 14 acres, we knew we needed to do one thing and we fairly actually achieved our objective by doing nothing. We stopped mowing about half of it. We depart about six ft on the sides to make it seem like it’s cared for, however then the remainder of it grows actually fantastically on this form of 18- to 30-inch-tall, meadowy combine. And as quickly as we began doing that, we noticed birds flying in there, even foxes leaping by way of it. And so we knew we had been heading in the right direction.
Margaret: And that, similar to what you mentioned, that leaving the sting mown simply says, “We’re right here, we’re doing this, however we’re doing it in a gentler manner,” which is absolutely necessary. I’ve positively been experimenting with my areas of turf, which components can I unmow and make it seem like a part of the plan versus simply, “Oh, she’s being messy.” [Laughter.] So yeah, it actually appears stunning within the pictures I’ve seen of Stoneleigh and the lawns.
So generally folks, one of many onerous issues about remodeling components or much more of our gardens to native vegetation, is sourcing the vegetation. And one of many issues I beloved listening to was that you just go on adventures in a number of the different nature preserves, a number of the different preserved land, that Pure Lands, the group that made this Stoneleigh transition occur, that they’ve beneath conservation as nicely, or beneath administration and care as nicely. And also you get seeds from native, regionally applicable native natives, and I don’t know, cuttings I suppose, and who is aware of what, and develop these. So inform us just a bit bit about that.
Ethan: It’s actually particular, as a result of Pure Lands group that we’re a part of, additionally has 42 different nature preserves. About 23,000 acres that we get to roam, they usually’re a number of the most stunning properties in your complete area, in southern New Jersey and jap Pennsylvania as much as the Poconos. And we’ve got coastal properties. So if you happen to’re on the lookout for native vegetation, we actually can discover so many great examples of the range that’s on this area. And it’s superior. Who doesn’t love getting out into the woods? And if you happen to’re accumulating seeds to then deliver again and showcase to our neighborhood, it’s even higher, I’m telling you. It’s a very unbelievable alternative for us. And we hope everybody enjoys seeing these vegetation that they may not usually see, or they may be acquainted ones that they didn’t even know had been a part of their native ecology and panorama.
Margaret: Proper. It’s fairly thrilling stuff. And for me, one of the thrilling issues of all was to form of hear about, right here once more, you’ve gotten this formal place, there’s this, what’s 220-foot-long, stone pergola that’s like this magnificent century-old or older construction, this superb factor, nevertheless it had nothing rising beneath it. I feel you mentioned there was turf and nothing rising up and over it. And so that you’ve with that and different spots on the property, espaliers on the partitions of the property home and different locations, you’ve form of achieved this complete vertical factor, and never simply with vines. You’ve form of gone vertical [laughter]. So inform us about a few of these efforts. As a result of boy, oh boy.
Ethan: Now we have gone vertical. And it’s humorous as a result of that pergola, earlier than there’s something on it, the primary query we all the time acquired, “What’s that for? What’s that factor for?” And I’d say, “Nicely, it’s a promenade. And have you ever ever seen that present “Bridgerton” on Netflix? [Laughter.]
Margaret: Sure.
Ethan: Yeah. In order that’s made it far more relatable, as a result of now individuals are far more acquainted with promenading. So it’s a spot that you’d stroll, a romantic place. However as soon as we acquired these vines on it and planted it, and you possibly can see this actually romantic construction actually revealing itself with the vines, folks completely get it, and it’s a fantastic alternative to showcase a few of these vines. Individuals are usually afraid of vines, however that’s what makes them so interesting. They’re unpredictable. They’ll simply develop in all these assorted instructions. And if we put them within the correct locations, or new locations as you talked about, then they are often spectacular additions.
Margaret: And also you in all probability needed to perform a little homework, as a result of off the highest of a gardener’s head, they may not assume of a complete lot of various native vines. I imply, they could know the trumpet honeysuckle, Lonicera sempervirens. They may find out about that, or one or two. Nevertheless it’s not like all of us have a palette at our fingertips of, hey, what are my native vines? However you’ve gotten found out quite a lot of them to incorporate. Sure?
Ethan: Yeah. It surprises some folks to know that we develop about 100 totally different styles of native vines right here. And I feel my high three, I’m going to must say crossvine is No 1 [coral-colored vine, above, on estate house].
Margaret: And so what’s the Latin identify for crossvine?
Ethan: The Latin identify? Bignonia capreolata.
Margaret: Bignonia. O.Ok. And does it have form of orangey flowers, or coral-colored flowers?
Ethan: It does. And it’s principally evergreen within the north. Undoubtedly evergreen within the south. Has these large, stunning orange trumpets. There’s some crimson varieties, there’s now a yellow selection on the market. It’s actually stunning. And we’ve acquired this loopy variegated one, it’s known as Bignonia capreolata ‘Variegata.’ And it’s like no chlorophyll. It’s nearly white on the suggestions. And it flutters within the breeze and I’m pondering, how is that this factor feeding itself? Nevertheless it’s fairly spectacular, too.
Margaret: And so that you’re utilizing that, is that a few of that on the pergola? And is a few additionally elsewhere getting used vertically elsewhere?
Ethan: It’s. It’s on the pergola. We even have a kind of on our bushes. So we’ve got all these actually tall bushes. And after we see these naked trunks, we expect: What a chance to, as you mentioned, to go vertical. As a result of it actually extends the backyard in a special airplane. And never solely that, nevertheless it’s nice for, it creates a vertical freeway to the cover of bushes for bugs, for reptiles, for birds and mammals. So many nice issues come by utilizing vines within the backyard.
Margaret: Proper. In order that’s one in all your favorites. And any others? I imply, I discussed the honeysuckles and I really like the trick, nicely, the form of design trick you’ve gotten with these. Inform us about these. And in addition with the, what’s it known as, the trumpet creeper, the Campsis radicans, how you utilize the multi-colors of them collectively.
Ethan: Coral honeysuckle is my Quantity 2 favourite native vine, the Lonicera sempervirens. And we’ve had some enjoyable with it. We absorb three flower-color choices, a yellow and orange and a crimson, and we put them in the identical gap in a pair locations on this pergola. And it’s all grown collectively. When it flowers, it appears like fireworks. It’s like this explosion of various colours. And it’s enjoyable. We’ve achieved the identical factor with the Campsis radicans or trumpet creeper. Similar colours, orange, crimson and yellow. After which my third vine, I’ll say is wisteria, is my third favourite. For flower energy that’s.
Margaret: However not the wisteria that so many individuals have, which is an Asian species that’s really fairly invasive. In order that’s not what you’re speaking about, appropriate?
Ethan: No, we’re utilizing the American species. And the Asian species, and I lived within the south for a very long time, and Chinese language wisteria has wreaked havoc on the ecosystem. So we have to get away from utilizing these non-native varieties and keep on with the native ones, which are literally far more behaved, comparatively, for wisteria.
Margaret: And I feel it’s frutescens? Is that the species of wisteria? Wisteria frutescens? Is that proper? Did I make that up?
Ethan: That’s one which we use. And we use macrostachya, too, which is extra central, south central United States.
Margaret: Oh, I didn’t know there was multiple. See, that is the factor, is that we’ve got to do our homework as a result of, and go exploring when you’ve got 42 nature preserves [laughter].
Ethan: Sure.
Margaret: As a result of it’s not so apparent and it’s not in each nursery. All these items are usually not in each nursery, proper?
Ethan: No, no. It’s necessary to get out and discover. And that’s the place public gardens and nurserymen and girls actually can advance horticulture and landscapes, each private and non-private. And by the way in which, the macrostachya, I actually like nearly higher than frutescens as a result of it has for much longer panicles of flowers and it’s barely smaller.
Margaret: Didn’t know, had no concept. And then you definitely’ve additionally integrated plenty of native clematis vines, I feel, as nicely onto the pergola and elsewhere.
Ethan: Now we have, and I’m certain you’re a lover of clematis, too, due to the way in which it’s a bit bit extra dainty than most vines. You’ll be able to let it ramble on shrubs, on particularly evergreens, it appears nice on smaller evergreens. It could possibly simply form of weave by way of the foliage. After which these flowers, that are spectacular, actually form of stick out in opposition to the inexperienced.
Margaret: Yeah. The factor that’s nice additionally, is that you just, guys experiment. You push the vegetation to do various things. And so forth that pergola, you’ve gotten some shrubs and nicely, some bushes that, so in different phrases, not vines but. You’re coaching them, upward pruning them and inspiring them to go up on the pergola. So inform us about that, as a result of I feel that’s one thing that quite a lot of us don’t know how you can do, that different woody vegetation might be inspired to behave in a vertical method as nicely.
Ethan: Vegetation are one thing that we are able to actually use our creativeness. And what’s so enjoyable about horticulture and is that this mixture of artwork and science, and so we are able to manipulate vegetation in all these other ways, however they do comply with actual world guidelines of nature. So we do must be cognizant of that.
However we’re utilizing yellowwood, which is a weeping selection known as White Rain, Cladrastis kentukea ‘White Rain.’ And we’ve leaned it in opposition to the pergola and are coaching it throughout the highest. And if you happen to’ve ever seen yellowwood flower, it form of does it each three years; it’s fairly shy. When it does, all of them flower as soon as it looks as if. And in order that has these lengthy panicles of white flowers, nearly like wisteria. You get a wisteria impact when these items cling down by way of the pergola,
Margaret: Huh. Yeah. And I feel another weeping, perhaps a weeping redbud, a white-flowered weeping redbud, if I recall appropriately, you’ve used that. You’ve educated that in a much less tree-like manner as nicely.
Ethan: We’ve educated that on a few of our columns all through the backyard, so simply we’re wrapping it round. Minimize off the lateral branches, after which when it flowers, you get these white pea-like flowers in opposition to the stone. Or espaliering redbuds on the partitions of the home, too. And so we’re taking this plant that’s identified for its flowers and utilizing it in all these other ways. And that’s why I feel for us, cultivars are very efficient, as a result of it actually opens up the use for vegetation and the panorama and all these other ways that may be dwarf, perhaps columnar, they are often weeping. Nevertheless it permits much more variety in how this native plant can be utilized.
Margaret: Nicely, with the redbuds, there’s a number of the cultivars which have the darkish foliage. Have you ever used a few of these? Purple foliage.
Ethan: We love these. Yeah. One, we’ve got one known as ‘Black Pearl’ on the facet of the home, and we use ‘Merlot,’ ‘Forest Pansy’ and plenty of different totally different varieties. The redbuds have actually exploded, haven’t they? There’s so many alternative cultivars on the market now.
Margaret: And so to espalier them, you’re coaching the branches by, you’re pinning them in your case to stone, or it might be different siding, or it might be a trellis or no matter. You’re utilizing eye hooks or one thing and wire, or what are you doing?
Ethan: We’re drilling proper into the mortar. We simply take a drill, hammer drill, and put within the eye hooks, screw them in there, and begin slowly and small and get your fundamental branches, the framework, in place. And then you definitely’re simply trimming the lateral branches after which thinning it within the heart as nicely, to form of expose the interior form of structure of the limbs.
Margaret: I’ve a buddy who loves… He’s an skilled horticulturist for a few years, and he likes to espalier issues, and he has witch-hazels and every kind of issues espaliered in opposition to, he has a board fence, a flat, nearly like a wall-type fence, round his backyard. And it’s simply, I simply am like, oh my goodness, have a look at that. I by no means thought to do it with what he does it with. And you’ve got the identical form of intuition, which is to offer it a attempt. So if I wished to do, say, witch-hazel, and I consider you’ve achieved some, what do I do? I cut back the variety of fundamental stems first? Otherwise you begin with a younger plant, I assume, to begin with, don’t you?
Ethan: Sure. Nicely, to begin with, I feel your buddy and I’d get alongside very well, by the way in which [laughter]. I really like the espaliering witch-hazels. So yeah, you begin with the younger plant. I feel that’s in all probability crucial factor. And actually, generally you see a plant within the nursery, and it might be a bit bit misshapen from an accident or one thing else, and perhaps one facet of it’s gone. And quite a lot of occasions vegetation will form of encourage you to make use of them in sure methods. So generally you’ll see one, nevertheless it’s like that’s already flat on one facet, so it’s half the work is already achieved. In the event you don’t have that, you may merely trim the again branches off and the entrance, and also you nearly make it two-dimensional. After which begin small, as you mentioned, and easily lower the branches that develop out away from the ball off, and fasten those which might be rising laterally in methods, within the sample that you really want.
Margaret: Yeah. As a result of once I see it in a proper backyard, or there’s an orchard close to me and a woody plant specialty nursery not removed from me, and the particular person there does stunning espaliers with fruit, with totally different styles of fruit bushes and so forth. They usually’re simply so stunning. I imply, they’re irresistible. They’re simply attractive. And but, I feel we gardeners, common house gardeners, that assume, “Oh, I couldn’t presumably try this.” However what you simply mentioned is all it takes, proper? [Laughter.] I imply, yeah.
Ethan: It’s actually fairly straightforward. It appears sophisticated, however I feel while you’re beginning out gardening and even skilled gardeners, generally we’re afraid to make errors, however I feel we’re actually fortunate that gardening is so forgiving of errors, of what we do incorrect. And so it’s nearly a part of, not nearly, it’s a part of gardening and the expansion, and what creates a lot of the magic of what we do. So I’d simply encourage folks to take a leap of religion. Go for it. In the event you mess up a bit bit, it’ll in all probability be high quality. They’re vegetation they usually develop again. It’s like hair, proper?
Margaret: Sure. Normally, often. And so we’ve talked a bit bit about vines and stuff you deal with as in the event that they might be vine-like, however conversely, you’ve gotten additionally educated some vines just like the American wisteria into shrubs, haven’t you?
Ethan: Now we have, and that’s been quite a lot of enjoyable. Generally folks may need to use a plant like wisteria of their panorama, however they could have a small property, so you may prune it like a shrub and maintain it in a smaller house. We’ve achieved that with woodvamp, Decumaria barbara, as nicely, and at present have one going with American bittersweet, Celastrus scandens, as nicely. Simpler with these woody vines which might be form of greater and heftier.
Margaret: And so once more, do I begin with a younger plant and stake it up or one thing? Or what do I do to get going?
Ethan: Staking it up is a superb first step. Establish your central chief after which take away, once more, it’s form of like this worth factor: Simply slowly over time, take away these smaller branches and deal with maybe three or 4 fundamental branches to be the construction of this plant. After which with the wisteria, we trim it proper after it flowers as a result of it sends out these little tendrils, you understand how it does. Minimize these after which all year long, you may form of simply snip them again, too.
Margaret: I simply wished to ask you about a number of the hedge creations you’re engaged on, as a result of that’s the opposite factor is that is, once more, this 42-acre longtime property with quite a lot of historical past to it. And but it was very open, you advised me, while you first got here there and there weren’t quite a lot of defining hedges and so forth. And you’re doing that not with the same old suspects, yew and privet (goodness forbid) [laughter], however you’re doing it with native vegetation. So what are a number of the hedging specimens that you just’ve had some success with, that you just’re liking. What’s taking place?
Ethan: We’re utilizing quite a lot of various things, and it’s, once more, like espalier, you actually can, if it’s a plant that takes nicely to shearing or pruning, you may hedge it. And in order that’s our strategy. We’ve used a dwarf number of Magnolia grandiflora known as ‘Teddy Bear,’ and it’s actually stunning, about 16 ft tall. It has these tight interior nodes and actually shiny leaves. It’s been a lovely hedge.
However we’re actually into creating combined hedges as nicely. And so we like that as a result of with one species in a hedge, it may be useful to far fewer animals than a combined hedge. So it additionally creates a extra resilient plant or planting within the panorama, so if illness impacts one plant, it’s not going to have an effect on all of them, hopefully. And so we combine all these various things. I discovered that Viburnum dentatum, arrowwood is absolutely great. Carpinus [C. caroliniana, hornbeam] is absolutely great.
However we’re doing issues with redbuds, too, placing them in these hedges. And American styrax, Styrax americanus, we’re placing these in hedges, and Hydrangea arborescens, and naturally all of the evergreens like Thuja, arborvitae, they work nicely to combine in. However I feel you may let your creativeness run wild for probably the most half.
Margaret: And so these are like bio-hedges. These wild hedges that embrace, like I mentioned, they will have a number of species and, yeah, attention-grabbing. So it’s like a mosaic, like a residing mosaic. Fascinating.
Ethan: The hot button is to shear them, to make them, once more, identical factor with chopping the 6-foot strip on the fringe of the no-mow. And also you simply need to ensure that it’s understood that that is intentional and cared for. So shearing it, and maintaining it tight actually makes it extra legible.
Margaret: So do you plant them extra-tight in comparison with in the event that they had been only a single specimen? Do you plant them a bit tighter than you’d?
Ethan: We don’t plant them any tighter, nevertheless it’s humorous as a result of folks will see our hedges they usually say, wow, it appears like they’re so tight. I’m like, nicely, if you happen to had been planting arborvitae, it might be the identical distance. So I feel it’s simply this getting used to a special palette of vegetation for hedges.
Margaret: Fascinating. Nicely, Ethan Kauffman, I’m actually, I’m simply so impressed with what you’re doing at Stoneleigh in Villanova, Pennsylvania, and simply additionally actually struck by the truth that it’s so welcoming and even free to the general public and so forth. I’m so glad that we had been launched and I’m so glad to be taught extra. So thanks for making time right this moment. Now exit and make extra hedges. I hope I’ll discuss to you quickly
Ethan: It was a pleasure to be right here. Thanks.
