our classic formative garden books, with ken druse
DO YOU REMEMBER your very earliest gardening books—the ones that transported you into the world of plants, whether that was last year or years ago? Or other books that have earned a permanent spot on your bookshelf as old trusted friends along the way? Ken Druse and I got to talking on the phone about our favorite formative volumes the other day, and decided we’d let you in on the conversation, too.
My regular alter ego, Ken Druse, needs no introduction, but he is of course the author of not a small number of gardening books himself, 20 at last count, including some I know changed the way I look at plants. He’s back today to take a stroll through our mutual garden bookshelves.
Plus: We’ll have a giveaway of a couple of favorites; enter to win in the comments box at the bottom of the page. Note that we checked that all of these books are available–often used–with a little Google searching for those that are out of print. With the ones I’ve given Amazon links for, there are used copies in all prices and conditions available, so dig deep.
Read along as you listen to the March 15, 2021 edition of my public-radio show and podcast using the player below. You can subscribe to all future editions on Apple Podcasts (iTunes) or Spotify or Stitcher (and browse my archive of podcasts here).
our formative classic garden books, with ken druse
Margaret: Hi, Ken, how are you?
Ken: Hi, I’m Margaret. I’m your alter ego?
Margaret: Yes, I think so. I’ve decided. Some days I’m you [laughter].
Ken: I thought that I was like Clark Kent and you’re Superperson or vice versa [laughter].
Margaret: Well maybe we should get a couple’s therapist and see what they have to say about that.
Ken: What’s your take on capes? No, books. Books.
Margaret: Books. So I think what we should do is have a giveaway of one of the books, but I don’t think we know yet until we chat, which one it’s going to be. So we’ll tell that with the transcript, but there will be a book giveaway of one of these goodies.
So, do you remember your first sort of gateway books into this world, where you and I have spent more decades than we may care to admit [laughter]?
Ken: I’ve been asked this question many times-
Margaret: Oh.
Ken: … and the first book that comes to mind is, I know, it’s probably the first book that comes to mind for you, too, because it’s seminal, and it’s “The Principles of Gardening,” by Hugh Johnson.
Margaret: Oh, yes, yes, yes. It’s a very unusual book.
Ken: Well, he mostly known as a wine author, writer, and blogger now, too, he’s still doing it. But this book contains mostly two-page color spreads on all sorts of aspects of gardening with short text, big captions and photos. The Dorling Kindersley books, kind of… this was the progenitor in some ways. But there’s photos and drawings and paintings from history of gardening to greenhouses, to wind and rain, to gardens around the world, to landscape history, to plant families and names, to alpines and hedges.
It’s just everything—perennials, trees, color design, and they’re all in these bites that are two to four pages, and it’s a turn-on, but it’s also… Well, he has history on landscape architecture and William Kent. You just learn so much, but it’s so easy to digest, and someone like me who likes non-fiction and doesn’t read so well, it’s perfect.
Margaret: The book is so different from the table of contents of a first gardening book that you would expect. So it doesn’t have like perennials. I mean, it does have perennials, but it doesn’t have… or chapters like spring, fall, summer, winter, it’s not traditional in its organization. But you’re just transported into all of these different, as you said, these different ways of looking at and connecting really to the garden—through the weather. And so it’s not like sections like spinach—how to grow spinach, or how to grow tomatoes. Do you know what I mean?
And it’s like historical examples of different cultures in history, how they’ve related to the garden. And I mean, it’s really, it’s a must. I think it first came out in ’79 and then was revised in ’96 or ’97, so there’s old copies out there, but it’s a must. It goes on both our lists, right?
Ken: Well, I don’t know about your list, but definitely. It probably does.
Margaret: So that was one of your early, early books that you-
Ken: Yes.
Margaret: Yeah. Yeah. I mean, I think quite a different kind of book, in a more traditional structure and so forth, that would be right around the same time, maybe a couple of years earlier, was James Underwood Crockett’s “Crockett’s Victory Garden.” And we’ve talked about that probably in the past. I mentioned it a lot, because it was my first how-to book. But it’s outdated because things are different now, chemicals that he used and so forth, we wouldn’t do a lot of those things. But the idea of looking at the garden through all the seasons is still very important. And so, it was sort of the companion to the PBS series that he did and so forth. Yeah.
Ken: When gardening was actually on television.
Margaret: Yes. Remember, remember? So what else was early for you in the formative, Ken Druse’s formative-
Ken: I think in the earliest days I was into indoor gardening when that was… and it’s back, and now people are doing that again. But yeah, I started indoors, in an apartment. And I think one of the earliest books, the first books, was “Garden in Your House,” by Ernesta Drinker Ballard. It’s a black-and-white book with photos by her husband, Fred, and it’s arranged in exposures. So, there’s plants for north-, east-, west-, and south-facing windows.
Margaret: Oh.
Ken: And I really… I just read it, and re-read it, and re-read it. And that reminds me of kind of a plant porn book, “Exotic Plant Manual” by Alfred Byrd Graf, which is a reference book. Do you know that book?
Margaret: I have seen the book. I don’t own the book. I don’t own either of those book two books actually. Huh.
Ken: I would spend hours with the black and white “Exotic Plant Manual.” I don’t know, it weighs about 4 pounds. And I just would look at the plants and look at the plants. The plants for greenhouses, windows, and warm climates outdoors, and how to grow them, and some description of what they’re like. And then a small version came out of that. And then a big version came out called “Exotica,” and then a big version in color came out called “Tropica.” But “The Exotic Plant Manual” is… I don’t know how I could do it. I would look at that for, really, actually, hours over and over, and learning so much.
Margaret: Interesting because the “Exotica” and “Tropica,” the later sort of iterations, I have both of those, but I don’t think I have the original. Yeah. And it is, it’s really… Well, and I think those titles… I think, actually, the title “Exotica” really describes that sort of genre of book. It’s perfect for those books right, because it is… It’s like you’re saying, you’re like transported and you couldn’t close the original one.
It’s like you said, you just kept looking and looking at all these exotic creatures and wanting to learn more about them and where they came from and so on and so forth.
Early on, I got some house houseplant books, too, and I still have it on my shelves, especially Thalassa Cruso. She was British-born, but lived in the U.S. and I think she… didn’t she make that… yeah, it was a public TV show for WGBH in Boston. She had a show, “Making Things Grow,” and don’t… wasn’t she on like Johnny Carson or something? Did I make that up?
Ken: She was on “The Tonight Show” with Johnny Carson. I didn’t see those originally, and I’ll bet you can still find them on YouTube. I wouldn’t be surprised, because they were kind of funny. And it was like the cooking things where she would try to do something and he’d be making faces in the background, but she was a very good sport. And that book… She would have sort of projects, so it would be indoor plants, but it would be: how to make an indoor plant tower.
Margaret: Right, right, right, right. Aspirational [laughter]. Yeah. That was… I bet hers was one of my first… Crockett had an indoor garden, I think it was just called like “Crockett’s Indoor Garden” or something like that book too. But Thalassa Cruso’s would have been one of my others, and early-earlies.
My earliest books, when I started thinking about making a garden outdoors, not just having houseplants, were kind of like hippie dreams and back-to-the-land focused, and they weren’t horticulture exactly. And I still have my copies of these, which were vintage even at the time, what was it called—”Five Acres and Independence,” which was a 1940 book by someone named M.G. Kain. And it was, again, a back-to-the-land Bible, and then Helen and Scott Nearing’s in the 1950s-
Ken: Oh, wow.
Margaret: ... they wrote “Living the Good Life.” They were in Vermont and then eventually to Maine, and they were an inspiration for so many people that I’ve met over the years, including Eliot Coleman, the great organic farmer and inspiration to an entire generation, since they inspired him. So the Good Life series of books, especially “Living the Good Life,” I don’t know. I just, I wanted to learn to can and put up my food and grow my own, and it just, again, it was like aspirational in a way.
And I guess that’s why… that’s what led me not to have a garden in the city where I grew up. or even on Long Island at the beach front or whatever, but to come to a rural place. I think it was really those books that directed me north into the Hudson Valley/Berkshires area—you know what I mean?—into a rural setting were books like those. And then, of course, Ruth Stout. Did you ever read any Ruth Stout books? Speaking of the 1950s?
Ken: Yeah. When you’re saying that, I always think of the bales of hay, when you say-
Margaret: [Laughter.] I know. I know. What she would call “mulch gardening,” meaning throw it all down on the ground, like piling… I mean, I think they ended up calling that recently, like lasagna gardening, and in farming, they call it sheet mulching sometimes. But she just would pile stuff up to suppress the weeds and tease it back, and plant in between it. And yeah, I mean…
And the thing about that and about the sort of hippier books, is they hold up because, again, the chemical thing, they never used chemicals. It was sort of organic gardening before we’ve talked about it exactly that way. And so, whereas some of, as I said before, the Crocket stuff and so forth, it feels a little wrong, because it’s a lot of times about a chemical intervention.
So these more natural, sustainable, etc. books kind of hold up technically, even though they’re funky and funny, and obviously, from another period. Again, they were even vintage when I read them or you read them. But, yeah, Ruth Stout, definitely had… Her books were like “How to have a Green Thumb without an Aching Back,” I think that was one title and “Gardening without Work.” And she gardened in Connecticut, and anyway, she was born in Kansas, she gardened in Connecticut. But she’s definitely was a pioneer of… I don’t know, I just loved her. I love her. So I could still read those books.
Ken: Well, those books, which are kind of general advice, the thing about these old books that bugs me is that the plant names have all changed so much.
Margaret: I know.
Ken: It’s frustrating. Not that we can’t figure it out, but that’s one thing about old books. Right?
Margaret: Right. Right. Right. And I next dipped into a British phase, because I think when you and I were really starting to garden keenly and became garden writers around that time, we Americans all looked to the British for our inspiration. It was… Do you know what I mean? They were/are, I mean, they were those that you look to for inspiration, leave it at that.
Ken: Well, they just had been doing it a whole lot longer.
Margaret: Right, right.
Ken: And there were a whole lot more, and they have so much more forgiving weather, and great soil, and the temperature’s just wonderful, and long hours of daylight in the summer. So it’s not really fair, but just like everything, when you say a house is old here, it’s like 1840. And when you say a house is old there, it’s like 1610 or something [laughter]. They’ve just been doing all that stuff so much longer.
Margaret: Right. So we mentioned Hugh Johnson, we mentioned his “Principles of Gardening” already. Yeah.
Ken: Oh yeah. I don’t even think of that in that same group, but yes.
Margaret: No, no. I know, but I’m just saying, I was just going to bring up the idea of British… books from people from the U.K. And in preparing to talk to you today, I found that at 81, he’s still blogging. He has Trad’s Diary dot com, derived from Tradescant, or like Tradescantia the plant. And so he’s definitely one, but many others. I mean, obviously early on, I read vintage books by Gertrude Jekyll and so on and so forth. William Robinson, who’s Irish, not English, but William Robinson. Yes?
Ken: William Robinson, well, he did a book that was very popular called “The English Flower Garden,” I believe, but I had a book called “The Wild Garden”-
Margaret: Yes.
Ken Druse: … by him before that. And when we hear the word wild, we think native, but wild, in this case, is naturalistic, and he encouraged naturalizing plants. But he would show fields of daffodils and there is one native daffodil to Great Britain, so it’s different. But that book was… Just that whole style, just think how that influenced American gardening, even to this minute.
Margaret: Yes. And “The Wild Garden,” it’s credited with leading to the popularizing of the style of cottage gardening, looser, not the formal within parterres of boxwood, putting your flowering plants inside the rigid… it was like getting away from that. And he was a big critic of that formality, really.
Ken: Yeah, it’s a backlash.
Margaret: Yeah. Yeah. And so by loosening it up, then the cottage garden style, I believe, became more popular.
Ken: People don’t even know what bedding is now. You say bedding out-
Margaret: Bedding schemes.
Ken: … or carpet bedding, people don’t… Americans don’t know what that is.
Margaret: Right. So that sort of formal stretches of color within usually sort of geometric-shaped, again, like boxwood and so forth parterres and yeah, yeah.
Ken: Mostly annuals, too.
Margaret: Yes. Lots and lots of color.
Ken: That’s a really long story, because Great Britain colonized all these places that had annuals, and then they could make greenhouses inexpensively for the middle class. It’s a big, long story, and then William Robinson said, “To heck with this.”
Margaret: Right. Loosen it up, baby.
Ken: I want to see the woods, right?
Margaret: Loosen it up. Right. Right. And he was very influential in garden writing, garden journalism, not just his own writing, but he started “The Garden” magazine and “Gardening Illustrated” and other… He founded a couple of gardening magazines, etc., so he was… I mean, I highly recommend “The Wild Garden” as a book to read.
And when he… With his success, he ended up buying Gravetye Manor, which was another English home of note, and so forth. So lots to learn, I think, even now from his books. I think that The Wild Garden, I think it was written in like 1870 when he was in his 30s or something, so it’s an oldie.
What about Margery Fish? Did you read any of her books?
Ken: Well, I was going to just say that Gertrude Jekyll was his disciple.
Margaret: Oh, was Robinson’s, right.
Ken: She wrote for his magazines and her books, like “Wood and Garden,” her books were enormously popular and she was, still incredibly popular. But anyway, she worshiped at his feet until they probably had a fight over some sentence or two [laughter]. Sorry. Now, where were you going?
Margaret: I was just going to say, did you ever read any books by Margery Fish, a bit more contemporary?
Ken: Yes. And I think I had her “Gardening in the Shade” book. I remember… Reading her was… they say these things like having a friend in the garden?
Margaret: Yes.
Ken: It’s really like having a friend in the garden.
Margaret: Yes. Yes. She, Margery Fish—so the book of hers that I love and recommend, and I think it was reissued maybe 2002 or something, I think as recently as that. It’s this tiny little book and it’s called, “We Made a Garden.” And apparently her working title, which I love this, was “Gardening with Walter,” Walter being her husband. And basically it’s like, between the plantsmanship and the inspiration that you get from reading it, but also the, “You’re not putting that over here.” “Yes, I am.” “No, you’re not.”
Ken: [Laughter.]
Margaret: You know what I mean? But her publisher said, “I’m sorry, nobody will buy a book called ‘Gardening with Walter.’” So they called it “We Made a Garden.”
Ken: Oh, I think that’s a better title, actually. Not as funny.
Margaret: I know, but anyway. But Margery Fish, I love her. And maybe that’s one of the ones we should give away, because it is, again, it’s been reissued, and it’s out and so forth. Any others you want to share?
Ken: You’re mentioning a husband-and-wife team, and that makes me think of, when I lived in Rhode Island. But I had a book that was, everybody had this book, “America’s Garden Book: The Only Book You’ll Ever Need to Plan, Design, and Grow your Garden,” by Louise and James Bush-Brown, people call it Bush-Brown.
Margaret: They call it Bush-Brown. Yes.
Ken: And that was a general book on just about everything, in black and white, my copy was black and white; I don’t know if it’s been reissued with color. But it had hedges, paths, things like that in a very digestible way and very thorough. But they were from Providence. But I used to walk by where they used to live.
Margaret: Huh? I bet you read “Green Thoughts” by Eleanor Perenyi.
Ken: It’s funny. I’ve just was talking to someone about that book, and I can’t remember who it was, but we both agreed that it was the right book at that time [laughter].
Margaret: I think it was like ’80-ish or ’81, or is that right? Something around there.
Ken: Is it really that long ago. Huh?
Margaret: Yeah, I think so. I think it was ’81. And it’s just 72 little essays, some of them are half a page, some of them are two pages long, strung together alphabetically, you know what I mean? So it could be, T is for trowel and P is for petunia, whatever. It’s just… Those are not necessarily two of them, but it’s idiosyncratic, it’s not linear.
Ken: I’m sure P was for peony [laughter].
Margaret: Maybe. Yeah, it was called “Green Thoughts” from Eleanor Perenyi. That’s another one that’s been reissued repeatedly. But the cultural stuff doesn’t hold up, for me, because again, the recommended ways of feeding plants and dealing with pests and so forth, seems so out of date, or they are so out of date.
Ken: Yeah. Well, you’re right. [Laughter.]
Margaret: So any others in the last few minutes that you want to share, that you are keeping on the shelf?
Ken: Keeping on the shelf. Why do I have “Wyman’s Gardening Encyclopedia”?
Margaret: Me, too, honey. I have it, too. And it’s a one-volume… It looks like a thick dictionary, kind of a book, and that’s what it is like it’s alphabetical, isn’t it? You can look up each entry, pruning or whatever, or a Latin name of a plant.
Ken: And I have “Hortus Third,” which I haven’t touched for years, and probably all the names are wrong in that, but we used to go to that for plant names.
Margaret: Right. And now you go to… I go to theplantlist.org, which is the multiple botanical institutions around the world, collaborating on the latest Latin taxonomic correctness. And what’s named what, and what’s a synonym of what. So, now I do it online. I don’t even have a book for it.
Ken: You were talking about the Thalassa Cruso, and I was thinking she was like the Julia Child of indoor gardening [laughter].
Margaret: That’s well-put. Yes, yes, yes.
Ken: Later I would say on my reference list would be Michael Dirr’s “Manual of Woody Plants,” which is an enormously popular book. [More recent from Dirr: “Dirr’s Encyclopedia of Trees and Shrubs.”]
Margaret: Yes.
Ken: Lucky him, right?
Margaret: Yes. And it’s been updated and so on and so forth, and yeah. Yeah. But that’s a… it’s a reference book. It’s not a read from page one to page whatever, it’s a reference book; I use it as a reference book.
Ken: Although you could read it from page to page, and it has so much in it. And it seems to be every student, even kids who go to school for landscaping, they get that book.
Margaret: Yeah. So do you have one more that you want to tell us before we bid adieu?
Ken: Well, I guess in a way, I might say “Noah’s Garden” by Sarah Stein, which is-
Margaret: Oh, wow, yes.
Ken: … also many years later, but that really changed a lot of things.
Margaret: Speaking of loosening us up and making us look differently at… yeah, so speaking of wilder [laughter].
Ken: Right. Well, she wrote a book called “My Weeds,” I think. And then she got religion and she realized that, wait a minute, I don’t want to just let everything grow that wants to grow. I want to make it local and indigenous and native, and she did. And that got… That was revolutionary. That’s when the habitat garden [Ken’s book “The Natural Habitat Garden” that he and Margaret worked on together] came out.
Margaret: Correct. Yeah.
Ken: And we were promoting native plants-
Margaret: Yes.
Ken: … and now that’s not even outrageous.
Margaret: No, no. Well, Ken Druse, we’ve used up another segment. It’s good—I’m going to go dig through my book bookcase and put some on the bedside table. So thank you for reminding me of some of these, because some of them like Margery Fish are going to get another read. So thank you. And I’ll talk to you soon. O.K.?
Ken: O.K., great. Thank you.

Here in Southern California, it all started with Sunset’s “The Western Garden Book!”
Garden Witchery: Magick from the Ground Up By Ellen Dugan
I loved learning about the symbolism of plants.
One of my favorite vintage garden books was Peacock Manure & Marigolds; A “no-poison” guide to a beautiful garden by Janet Gillespie. This is the book that inspired my gardening style of using the resources around me to build healthy soil without chemicals. I remember reading it from front to back and if I see copies in used book stores I buy them for gifts.
For me it was A Year at North Hill by Wayne Winterrowd and Joe Eck. I love garden essays, and to find a gardening book written about my climatic zone was pure heaven. Perennials: How to Select, Grow, and Enjoy by Pamela Harper and Fred McGourty taught me a lot. The New American Landscape Gardener by Phebe Leighton was helpful in thinking about design. Caring for Perennials by Janet Macunovich helped with the nuts and bolts.
A.A. Milne’s book of poems for children: When We Were Very Young. My mom used to read it to me all the time, and there’s a one I never forgot about a dormouse who lives in a bed of delphiniums blue and geraniums red. The flowers make him so blissed out and lazy that the fusty old doctor is called- who promptly orders them ripped up and chrysanthemums (yellow and white) put in place instead. The dormouse then proceeds to tuck his head into his body tightly, so as to block out the sight, and keeps on dreaming of delphiniums and geraniums.
I’ve finally escaped NYC after 20 years and am looking out on my first-ever expanse of arable (I hope) *land* and a table full of too many seeds that I’ve been unable to resist over the winter months, and yes, planning my inaugural garden around delphinums blue and geraniums red.
My mom got me started with Crockett’s Victory Garden.
“Away to garden” I loved your book and started me on my gardening book journey!
Square Foot Gardening.
Vita Sackville West was very inspirational, she wrote about gardening at Sissinghurst Castle, in Kent, England ,where she lived.
I remember reading Green Thoughts many years ago. I’d love to reread it along with We Made A Garden
I have a bookcase of garden books. Choosing a start for inspiration is impossible.
Suddenly winters are not long enough to read all the good books that are out there: old & new books!
But, so happy that it is spring!
Love old books! One of my favorites is The Nature Notes of an Edwardian Lady by Edith Holden. More observations than instructions but inspirational.
Scott and Helen Nearing’ s The Good Life, influenced my twenty something life…. Crocketts Victory Garden, and Organic Gardening by Rodale Press, as well….
At 65, with a a small yard but lots of sun and wildlife, I still adhere to an organic, compostable lifestyle. I have a productive, working compost pile, and both raised beds and inground beds. Retiring shortly, I will have more time to devote to my passion. I’d love to have “We Made A Garden”…. thank you
My first was The Complete Guide to Garden Flowers- An Encyclopedia of Garden Planning Edited by Herbert Askwith
Tottering in my Garden: A Gardeners’ Memoir and the Square Foot Gardener
My grandmother was a gardener (WWII ‘Victory Garden’) and a rosarian and as a child, I read the numerous volumes of the American Rose Society yearbooks from the 1940s and 50s, matching them to what was in her garden. Now too shady for roses, her backyard featured perennials and beds of roses that she would nurture. She also nurtured my life-long love of gardening before I could read, like around 4 years old, as she taught me the basics. As the Dr. E.M. Mills Rose Garden was in nearby Thornden Park, a 15 minute walk away, gardening became a permanent part of my life. Now, I’m mostly “gone native”
Thalasso Cruso- first the one on indoor plants and then because it was such good reading, the one on outdoor gardening, even though I lived in an apartment and didn’t have a place to garden yet. Katherine White’s book was inspirational. I bet you could tell our ages by the books we read first!
From the Ground Up by Amy Stewart.
I think the first gardening book that made an impression on my was “A Garden of One’s Own” by Elsa Bakelar. She lived in Ashfield where I live, and gardened in Heath, I think, as well, so her advice was very local. And it was a lovely book to read. Would love to try one of your give-aways! thanks! Leslie
I’ve gotten really interested in using native plants in the garden, so I love Doug Tallamy’s books (Bringing Nature Home, etc). Of course, Square Foot Gardening was one of the first vegetable gardening books I bought. While I am not organized enough to make it work, I gleaned some good tips from it. I guess Ruth Stout’s no work methods are more my speed!
Probably Maria Thun’s “Aussat Calendar” with all the interesting things about Permaculture – and the effects of the time of planting or transplanting…I still use it and it’s over 20 years since I started gardening.
The VIctory Garden
So many books…so little time…
Just finished Life in the Garden, by Penelope Lively (Viking, Penguin Random House, LLC, NY, NY)
Reflections on gardens and art, literature, growing things, time & memory in this marvelous little book.
Started in late 70’s with James Crockett’s Indoor Gardens followed by Square Foot Gardening in the 80’s. I have passed these much used and much loved books along to my daughter, now a fabulous gardener, too.
Loved hearing about so many books that are old favorites of mine. It was books like Crockett’s and Ruth Stout’s started my passion for gardening. Ken’s Making More Plants started me on propagation and I used it for as a reference for many workshops. Since I live in the deep south, regional authors were always good for specific to the location. Dirr and Armitage are always at hand and Elizabeth Lawrence for when I need a pleasant relaxing afternoon.
