CAN A HISTORIC formal house grow to be the house to a forward-thinking panorama of native vegetation? The crew 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 right 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 residence gardeners, too.

natives in a proper setting, with ethan kauffman
Margaret Roach: Yeah, so we did a “New York Occasions” 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 believe it actually does apply to residence gardeners who’re questioning, sure, however how do I take advantage of these vegetation? I knew the best way to 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 arduous to consider, however I began in 2016 in direction of the top, and the backyard has been open 5 years. So we’ve been within the panorama for the entire seven years, actually. And it’s been such a joyful expertise. This place was attractive after we received right here, and we had this unimaginable alternative, as you mentioned, to rework it to a backyard that not solely serves as a spot of leisure and rejuvenation for our friends, but in addition 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 apart from, I believe, Thanksgiving and Christmas, and what? On Tuesdays to Sundays, is that proper? But it surely’s free. It’s freed from cost, which is simply implausible. So welcoming, actually.
Ethan: It’s. And I believe whenever you stroll into Stoneleigh, you’re feeling that welcoming spirit, that kind of snug, accessible power. And possibly it’s the massive timber. We have now so many actually previous, huge timber right here, and you are feeling, I don’t know, I really feel kind of the sense of security and luxury below their boughs. So it’s actually a particular place.
Margaret: So this was greater than a century of historical past earlier than you all received there. I imply, this was an property on the Philadelphia Most important Line. And inform us a bit of 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 Most important Line has all these estates that have been constructed in the course of the nation place period, from 1870 to 1930, and Stoneleigh’s a type of grand previous estates. And it was a very magnificent and is an impressive 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 bear in mind after we first talked, after we did the “New York Occasions” interview and we have been simply attending to know one another, you instructed me that whenever you received there, there have been seven acres of pachysandra and I believe 14 of mown garden on this 42-acre property [laughter]. In order that’s not very ecological or that that’s fairly the alternative 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 believe, month, there have been simply two of us on the time, and we noticed this pachysandra; we have been simply so able to do away with it. So we didn’t have any tools, so we rented this mini-excavator and the 2 of us took turns and we ripped out about an acre of it, which truly turned our parking zone. So it was very satisfying that first removing of pachysandra. We’re nonetheless chipping away. I can promise we’ll be at it for a very long time, however I believe that’s what makes this place accessible too. We have now a small crew, it’s not occurring instantly. And so our friends and the people 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 residence.
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 might be treating it in a different way, or managing it in a different way.
Ethan: Garden is such an enormous a part of American tradition, and everyone knows that it’s tough on our assets, particularly water, and it’s not significantly productive for wildlife. So with 14 acres, we knew we needed to do one thing and we fairly actually completed our objective by doing nothing. We stopped mowing about half of it. We go away about six toes on the sides to make it appear like it’s cared for, however then the remainder of it grows actually fantastically on this kind 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 have 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 de facto vital. I’ve undoubtedly been experimenting with my areas of turf, which elements can I unmow and make it appear like a part of the plan versus simply, “Oh, she’s being messy.” [Laughter.] So yeah, it actually seems to be lovely within the images I’ve seen of Stoneleigh and the lawns.
So typically individuals, one of many arduous issues about remodeling elements 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 simply go on adventures in a few of the different nature preserves, a few of the different preserved land, that Pure Lands, the group that made this Stoneleigh transition occur, that they’ve below conservation as effectively, or below administration and care as effectively. And also you get seeds from native, regionally acceptable 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, and so they’re a few of the most lovely properties in all the area, in southern New Jersey and japanese Pennsylvania as much as the Poconos. And we’ve got coastal properties. So should you’re searching 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 should you’re amassing seeds to then carry again and showcase to our neighborhood, it’s even higher, I’m telling you. It’s a very implausible 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 have 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 sort of hear about, right here once more, you’ve got this formal place, there’s this, what’s 220-foot-long, stone pergola that’s like this magnificent century-old or older construction, this wonderful factor, but it surely had nothing rising beneath it. I believe 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 sort of executed this entire vertical factor, and never simply with vines. You’ve kind of gone vertical [laughter]. So inform us about a few of these efforts. As a result of boy, oh boy.
Ethan: We have now gone vertical. And it’s humorous as a result of that pergola, earlier than there’s something on it, the primary query we at all times received, “What’s that for? What’s that factor for?” And I’d say, “Effectively, 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 persons are far more accustomed to promenading. So it’s a spot that you’d stroll, a romantic place. However as soon as we received these vines on it and planted it, and you would see this actually romantic construction actually revealing itself with the vines, individuals completely get it, and it’s an awesome alternative to showcase a few of these vines. Persons are typically afraid of vines, however that’s what makes them so interesting. They’re unpredictable. They will simply develop in all these diverse 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 most likely needed to perform a little homework, as a result of off the highest of a gardener’s head, they may not suppose of a complete lot of various native vines. I imply, they may know the trumpet honeysuckle, Lonicera sempervirens. They could find out about that, or one or two. But it surely’s not like all of us have a palette at our fingertips of, hey, what are my native vines? However you’ve got found out plenty of them to incorporate. Sure?
Ethan: Yeah. It surprises some individuals to know that we develop about 100 completely different kinds of native vines right here. And I believe my high three, I’m going to should say crossvine is #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.Okay. And does it have sort 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 huge, lovely orange trumpets. There’s some pink varieties, there’s now a yellow selection on the market. It’s actually lovely. And we’ve received this loopy variegated one, it’s known as Bignonia capreolata ‘Variegata.’ And it’s like no chlorophyll. It’s virtually white on the suggestions. And it flutters within the breeze and I’m pondering, how is that this factor feeding itself? But it surely’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 type of on our timber. So we’ve got all these actually tall timber. And after we see these naked trunks, we expect: What a possibility to, as you mentioned, to go vertical. As a result of it actually extends the backyard in a special aircraft. And never solely that, but it surely’s nice for, it creates a vertical freeway to the cover of timber for bugs, for reptiles, for birds and mammals. So many nice issues come through the use of vines within the backyard.
Margaret: Proper. In order that’s one in every of your favorites. And any others? I imply, I discussed the honeysuckles and I like the trick, effectively, the kind of design trick you’ve got with these. Inform us about these. And in addition with the, what’s it known as, the trumpet creeper, the Campsis radicans, how you employ 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 soak up three flower-color choices, a yellow and orange and a pink, 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 seems to be like fireworks. It’s like this explosion of various colours. And it’s enjoyable. We’ve executed the identical factor with the Campsis radicans or trumpet creeper. Similar colours, orange, pink 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 truly 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 persist with the native ones, which are literally far more behaved, comparatively, for wisteria.
Margaret: And I believe 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 in case you have 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 vital 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 best way, the macrostachya, I actually like virtually 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 thought. And then you definitely’ve additionally included quite a lot of native clematis vines, I believe, as effectively onto the pergola and elsewhere.
Ethan: We have now, and I’m positive you’re a lover of clematis, too, due to the best way it’s a bit of bit extra dainty than most vines. You may let it ramble on shrubs, on particularly evergreens, it seems to be nice on smaller evergreens. It may well simply sort of weave by way of the foliage. After which these flowers, that are spectacular, actually sort of stick out towards the inexperienced.
Margaret: Yeah. The factor that’s nice additionally, is that you simply, guys experiment. You push the vegetation to do various things. And so forth that pergola, you’ve got some shrubs and effectively, some timber 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 believe that’s one thing that plenty of us don’t know the best way to do, that different woody vegetation might be inspired to behave in a vertical method as effectively.
Ethan: Crops are one thing that we will actually use our creativeness. And what’s so enjoyable about horticulture and is that this mixture of artwork and science, and so we will manipulate vegetation in all these other ways, however they do comply with actual world guidelines of nature. So we do should 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 towards the pergola and are coaching it throughout the highest. And should you’ve ever seen yellowwood flower, it sort of does it each three years; it’s fairly shy. When it does, all of them flower as soon as it looks like. And in order that has these lengthy panicles of white flowers, virtually like wisteria. You get a wisteria impact when these items hold down by way of the pergola,
Margaret: Huh. Yeah. And I believe another weeping, possibly 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 effectively.
Ethan: We’ve educated that on a few of our columns all through the backyard, so simply we’re wrapping it round. Lower off the lateral branches, after which when it flowers, you get these white pea-like flowers towards 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 believe 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, possibly columnar, they are often weeping. But it surely permits much more variety in how this native plant can be utilized.
Margaret: Effectively, with the redbuds, there’s a few 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 aspect of the home, and we use ‘Merlot,’ ‘Forest Pansy’ and quite a lot of different completely 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 might be coaching the branches by, you’re pinning them in your case to stone, or it could possibly be different siding, or it could possibly 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 predominant branches, the framework, in place. And then you definitely’re simply trimming the lateral branches after which thinning it within the heart as effectively, to sort of expose the internal kind of structure of the limbs.
Margaret: I’ve a buddy who loves… He’s an professional horticulturist for a few years, and he likes to espalier issues, and he has witch-hazels and all types of issues espaliered towards, he has a board fence, a flat, virtually like a wall-type fence, round his backyard. And it’s simply, I simply am like, oh my goodness, take a look at that. I by no means thought to do it with what he does it with. And you’ve got the identical kind of intuition, which is to provide it a strive. So if I needed to do, say, witch-hazel, and I consider you’ve executed some, what do I do? I cut back the variety of predominant stems first? Otherwise you begin with a younger plant, I assume, to start with, don’t you?
Ethan: Sure. Effectively, to start with, I believe your buddy and I’d get alongside rather well, by the best way [laughter]. I like the espaliering witch-hazels. So yeah, you begin with the younger plant. I believe that’s most likely crucial factor. And truthfully, typically you see a plant within the nursery, and it could possibly be a bit of bit misshapen from an accident or one thing else, and possibly one aspect of it’s gone. And plenty of instances vegetation will sort of encourage you to make use of them in sure methods. So typically you’ll see one, but it surely’s like that’s already flat on one aspect, so it’s half the work is already executed. If you happen to don’t have that, you’ll be able to merely trim the again branches off and the entrance, and also you virtually 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 fix those which can 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 individual there does lovely espaliers with fruit, with completely different kinds of fruit timber and so forth. And so they’re simply so lovely. I imply, they’re irresistible. They’re simply attractive. And but, I believe we gardeners, common residence gardeners, that suppose, “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 simple. It appears difficult, however I believe whenever you’re beginning out gardening and even skilled gardeners, typically we’re afraid to make errors, however I believe we’re actually fortunate that gardening is so forgiving of errors, of what we do unsuitable. And so it’s virtually a part of, not virtually, 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 individuals to take a leap of religion. Go for it. If you happen to mess up a bit of bit, it’ll most likely be wonderful. They’re vegetation and so they develop again. It’s like hair, proper?
Margaret: Sure. Often, often. And so we’ve talked a bit of bit about vines and belongings you deal with as in the event that they could possibly be vine-like, however conversely, you’ve got additionally educated some vines just like the American wisteria into shrubs, haven’t you?
Ethan: We have now, and that’s been plenty of enjoyable. Generally individuals would possibly need to use a plant like wisteria of their panorama, however they may have a small property, so you’ll be able to prune it like a shrub and maintain it in a smaller house. We’ve executed that with woodvamp, Decumaria barbara, as effectively, and at present have one going with American bittersweet, Celastrus scandens, as effectively. Simpler with these woody vines which can be sort of larger 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 good first step. Determine your central chief after which take away, once more, it’s sort of like this worth factor: Simply slowly over time, take away these smaller branches and concentrate on maybe three or 4 predominant 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 know the way it does. Lower these after which all year long, you’ll be able to kind of simply snip them again, too.
Margaret: I simply needed to ask you about a few 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 plenty of historical past to it. And but it was very open, you instructed me, whenever you first got here there and there weren’t plenty of defining hedges and so forth. And you might be 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 few of the hedging specimens that you simply’ve had some success with, that you simply’re liking. What’s occurring?
Ethan: We’re utilizing plenty of various things, and it’s, once more, like espalier, you actually can, if it’s a plant that takes effectively to shearing or pruning, you’ll be able to hedge it. And in order that’s our method. We’ve used a dwarf number of Magnolia grandiflora known as ‘Teddy Bear,’ and it’s actually lovely, about 16 toes tall. It has these tight internal nodes and actually shiny leaves. It’s been an exquisite hedge.
However we’re actually into creating combined hedges as effectively. And so we like that as a result of with one species in a hedge, it may be helpful 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 de facto great. Carpinus [C. caroliniana, hornbeam] is de facto 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 effectively to combine in. However I believe you’ll be able to 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, fascinating. So it’s like a mosaic, like a dwelling mosaic. Fascinating.
Ethan: The secret is to shear them, to make them, once more, similar factor with slicing the 6-foot strip on the fringe of the no-mow. And also you simply need to make it possible for it’s understood that that is intentional and cared for. So shearing it, and conserving it tight actually makes it extra legible.
Margaret: So do you plant them extra-tight in comparison with in the event that they have been only a single specimen? Do you plant them a bit of tighter than you’ll?
Ethan: We don’t plant them any tighter, but it surely’s humorous as a result of individuals will see our hedges and so they say, wow, it seems to be like they’re so tight. I’m like, effectively, should you have been planting arborvitae, it will be the identical distance. So I believe it’s simply this getting used to a special palette of vegetation for hedges.
Margaret: Fascinating. Effectively, 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 have been launched and I’m so glad to be taught extra. So thanks for making time immediately. Now exit and make extra hedges. I hope I’ll speak to you quickly
Ethan: It was a pleasure to be right here. Thanks.
