old-fashioned hollyhocks plus gmo petunias, with joseph tychonievich

A NEIGHBOR’S CHERISHED hollyhocks were in bloom the other day, looking dreamy. And then I saw some serious flower porn on Facebook featuring hollyhocks, with the perpetrator being none other than Joseph Tychonievich, author of “Plant Breeding for the Home Gardener” and “Rock Gardening: Reimagining a Classic Style,” a true plant nerd with a special love for old-fashioned things like hollyhocks.

Joseph wants to entice us all to grow them, and clue us in to which ones he recommends most (like the species Alcea hohenackeri, above), which he did on the July 24, 2017 edition of my public-radio show and podcast.

Tip: now (summer) is the time to start easy-to-germinate hollyhock seeds for bloom next year. Read along as you listen to the July 24, 2107 program using the player below. You can subscribe to all future editions on iTunes or Stitcher (and browse my archive of podcasts here).

Plus: comment in the form at the very bottom of the page to enter to win a copy of your choice of one of Joseph’s books.

And another bonus: as I scrolled through Joseph’s Facebook page looking at more hollyhocks, I also saw that we are both nuts enough to share a current fascination with recent headlines in the nursery-industry trade press about GMO petunias, so he and I talked about that, too, starting at 14:50 in the audio.

q&a on hollyhocks plus gmo petunias, with joseph tychonievich



Q. First, I should really thank you for taking time right now, because I know you’re, shall we say, a bit distracted?

A. [Laughter.] Yes, I’m standing next to piles of boxes because we are moving in a couple of weeks, but always happy to talk about hollyhocks.

Q. And when a gardener moves, it’s a big deal, because it’s not just the usual—it’s whoof!

A. More plants than anything are moving. [Laughter.]

Q. You’re going from the Midwest to Virginia?

A. Yes.

Q. And you will explore a whole different Zone, and plant-hardiness possibilities.

A. I’m going from Zone 5 to Zone 7, and I am already starting a list of all the things that I couldn’t grow before that I will be able to grow now.

Q. [Laughter.] Uh-oh, uh-oh. Will that include hollyhocks?

A. Hollyhocks are something that are very adaptable, so that’s something I can grow both places. That’s a check mark in their favor, I guess.

Q. One time on the show we talked about your passion for gladiola, or Gladiolus, or however we want to say it, and I think of that as an old-fashioned favorite, too, if maybe of a slightly different vintage. But hollyhocks: I don’t grow them any more, and I lust after them every time I see them in someone’s garden, but I was thinking:

Are they even in the garden centers? Do they sell them, and when do they sell them? What do they look like when they sell them—and I guess that is one of the reasons they are not pushed more, and more ubiquitous.

A. They’re something that you are really going to have to usually grow from seed, because they are a difficult plant to handle in a nursery, probably because they’re just so massive. They can be 6 or 8 feet tall, and that’s awkward to deal with in a little nursery part; they fall over, and they’re hard to ship. So you rarely are going to see them sold as plants in the nursery.

Q. And the ones that are the most traditional, the species that in your plant-breeding book you call “the poster child of the genus,” is that Alcea rosea [above]?

A. That’s the classic hollyhock, and that’s the biennial one. So it’s going to make leaves the first year, and then flower the second year, and then that’s it. A lot of people shy away from biennials, but there are lots of great perennial species as well that can be grown.

Q. It’s really a shame that people shy away from biennials, and when I buy them I’d rather buy them before they put their spike up, and let them get settled in my garden before they flower. Do you know what I mean? I don’t mind getting them young.

A. The right time to buy them would be the first year, when they are just in leaf, but that’s also a hard sell. A lot of people don’t want to buy a plant that’s just leaves; they want pretty flowers.

Q. So it’s either too tall—it can’t even fit into my car at the garden center if they could even make it work in a 2-gallon pot at 6 feet tall; that’s a mess. And on the other hand, and maybe the better time to buy it, it doesn’t look like much except a rosette of leaves.

A. So it’s a great garden plant, and a terrible plant for a nursery, unfortunately. [Laughter.]

Q. So we can grow them from seed, and we’ll talk about that in a minute. You said there are also other species?

photo from Select SeedsA. The one that you are going to find most often is Alcea ficifolia, the fig-leaved hollyhock. That’s a good perennial species. It’s a really beautiful one, and it gets a little less of the bane of hollyhocks, the rust fungus, on its leaves. That one you’re going to find available, and that’s a good perennial to start with. [Select Seeds offers a hybrid of ficifolia, above, called ‘Happy Light;’ a different hybrid is sold at Jelitto Seeds. Photo of ‘Happy Lights’ above from Select Seeds.]

Q. So that’s a perennial.

A. You might also look for a new series called the Spotlight series, which is new hybrid breeding, and they’re really great perennials with a wide color range, and is supposed to be really disease-resistant, too, though honestly I have seen rust on them in my garden as well. But the Spotlight series is really good; another perennial series of hybrids.

Q. I saw on Facebook a photo of one that I didn’t recognize, and you said in the caption: “My favorite #hollyhock, Alcea hohenackeri.” How do you say that? [Laughter.] [Photo, top of page.]

A. It’s one of those species that I have written a lot but have rarely said out loud. It’s a really beautiful perennial, and I have been really impressed with it. It has been long-lived for me, and has the least rust on the leaves of any that I have grown. And it has really silvery fuzzy foliage, which is really nice, and pale yellow flowers.

Q. Yes, the flowers were a beautiful pale yellow, and with that silver foliage it was very appealing. Like I said in the intro: flower porn. That was one of the pictures that got me.  [Laughter.]

A. And it’s such a great plant because it’s so easy. I’ve had it for years, and it’s in dry, sandy soil and I never do anything with it, and it’s just tough and blooms each year, and has really been a standout for me in the genus.

Q. With something like that, did you grow it from seed, or where did you find it?

A. I grew it from seed, yes, and there are a few sources that carry it. Really you’re certainly going to have to do almost any of them from seed, but luckily they’re really easy. They have big fat seeds that germinate no fuss, and make vigorous seedlings, so they are really easy.

Q. When would I start them, or does it depend whether it’s a biennial or perennial? How far in advance am I doing what?

A. Right now is a good time to start either biennials or perennials. If you start them in the summer they will have enough time to get leaves up, and bulk up, and flower for you next year. I often start them later, just because in spring I am busy with so much else. When summer calms down, I can sow out my hollyhock seeds, and there will be leaves this year and whether perennial or biennials, they’ll start flowering for me in the second year.

Q. The rust thing: this is a fungal situation. Tell people who might not know what the deal is. I had them years and years ago—the classic cottage-garden, edge-of-the-garden kind of flower, a backdrop thing—but they’d defoliate or get real nasty on the foliage. Tell us a little more about the rust, because that’s what undid it for me, and I didn’t know to try other kinds at that time.

A. Rust is a fungal disease and it makes these little orange bumps that look like rust…

Q. [Laughter.]

A. …so that’s where the name comes from. Like you said, it can be pretty ugly, and it can defoliate them. The classic one, A. rosea, is probably the most susceptible, and it can get pretty gnarly with the rust. Some of the other species are more resistant, but I have yet to grow one that’s immune.

Everything I grow gets at least a little bit. But there are two things you can do. One is to plant them at the back of the border, with something else in front, and let the bottom foliage get ugly and just plant something else so you don’t see it. Then also you can cut them back hard, like after they flower or even if they are just in leaf. If they get really nasty then cut then to the ground, and they will flush out new foliage that will be cleaner. [Cornell’s factsheet on hollyhock rust, with photos, for more information.]

Q. If you do that with the biennial types you need to leave at least one or two plants probably to sow some seed for next year—to be the sort of mother for the next generation? How does that work?

A. I’m always advocating home plant breeding, as you know. So if you have the biennials, I would say pick out your favorite ones—the ones that had the most flowers, or the least rust, that looked prettiest, and let those set seed, and whack everybody else back hard. And if you do cut them back after flowering, the biennials will often come back for a third year, so that’s a good way to extend the life of the plant.

Q. So it might be sort of “biennial/short-lived perennial.”

A. If they don’t spend any energy on seed, often they will come through for another year.

Q. So back of the border is a good idea, with something that covers its legs as you said.

A. And they are so huge. I saw one that a neighbor is growing, and they fertilize like crazy, and it is literally like 10 feet tall.

Q. [Laughter.] The hollyhock that ate the garden. That’s a big plant.

A. It’s so massive, it’s unbelievable. If you put that in the front of the border it is going to block everything else, so put it in the back, and let it have a little rust.

Q. What about color range and flower forms and heights—you just talked about a neighbor who feeds them a lot and they are 10 feet tall, and you mentioned 6 feet earlier. Do the different species vary in size and color?

A. So the color range can go all the way from black—there are some nearly black flowers– through reds and purples and pinks and pale yellows. There are not a lot of strong yellows.

There are double-flowered forms but I don’t like them, but if you like big powder-puff flowers…. There is also a new series called the Halo series that’s beautiful.

Q. Yes. [Above, two of the Halo series; photos from Annie’s Annuals.]

A. It has this dark eye in the center, and they are gorgeous. They get so much rust in my garden, though. But the flowers are really spectacular and an interesting new pattern.

Q. I read about those. What I recall that years ago when I would get the seed it was a mix—I couldn’t just get the pale yellow or it was unusual to just pick one color. I have seen at places like Select Seeds’ catalog—and I think they may have plants and seeds—that she has single-color strains (and a mix, too). And also Annie’s Annuals, out in California, I think Annie’s has a lot of those Halo ones, actually—and it may be that they get less rust there, in a different environment than we have.

A. Definitely if you have less summer humidity, the rust is less of a problem.

Q. So that would make sense.

A. It really depends on where you are, how much of a problem it will be. Another place to look is Jelitto Seeds.

Q. Jelitto, right.

A. They’re in Germany, and have actually done a bunch of breeding. They have a new line of perennial forms. They have a really nice one called ‘Blacknight,’ which is that black flower which has been only in the rosea, the biennial, which is pretty prone to rust. But ‘Blacknight’ is perennial and more disease-resistant and has really cool nearly black flowers. [‘Blacknight’ photo above from Jelitto.]

Q. I might have seen that at Annie’s.

A. I think Annie’s is carrying it, and if she has plants, you can order them, or you can get seeds from Jelitto.

Q. I think Select Seeds has the ‘Nigra’ one. So there are some ways to get the single color now if you don’t want the riot of color thing that is the old-fashioned, cottage-garden look. So heights—from like 4 feet up?

A. I think 4 feet is about the shortest. There are ones that are annuals that will flower the first year from seed that are really short, which I don’t see the point to. [Laughter.] I could grow lots of 3-foot-tall perennials or annuals.

With most of the perennials, it really depends on how much you water and feed them, especially the biennials during that first season when they are getting up the energy to grow. I am kind of a lazy gardener and they fend as they will, and I don’t fertilize or irrigate, and the deer eat them down occasionally. Most of mine come out around 5 or 6 feet. If you give them rich soil and regular irrigation, you can push them to 8 or 10 feet.

Q. Wow.

A. When they’re really huge, you’ll probably have to stake them, because they are top-heavy, but you can really make a fun statement with them if you pamper them a little bit.

Q. I guess that’s why people plant them near their fence because you could always tie them to the fence. [Laughter.]

A. I’m terrible about staking.

Q. Me, too.

A. I don’t pamper them too much because I know they are just going to smash in the mud if I grow them too tall.

the news on gmo petunias

Q. So hollyhocks: We gotta get us some.  And petunias: I laughed so much when I saw it on your Facebook page, because you might be the only other nut I know who reads these stories. I got so excited—this was around mid-May—and I think it was in “Garden Center” magazine or at least their website or e-newsletter. The first headline was: “Breaking: Finnish report prompts petunia genetics investigation in the U.S.”

A. [Laughter.]

Q. And then a few days later, there was the follow-up story:

“Unauthorized GE [genetically engineered] petunias: USDA, industry weigh in.”

It’s all very grave and serious, and maybe we shouldn’t laugh as maybe it is grave and serious. But what happened with petunias that turned out to be genetically engineered—and this is not all petunias, but we’ll explain that. Give us a little backstory.

A. It seems to me as this story has unrav…unfolded…

Q. [Laughter] Unraveling.

A. [Laughter.] Yes. Back in the 80s, actually, academics moved a gene from corn into petunias. When they moved that gene from corn into petunias, it turned the flowers orange. And they just did it in a lab, to try to figure out what does this gene do, basically. and then, there was one paper published on it, and then this guy was walking down the street in Finland and saw these orange petunias and said, “Hey, when I was in graduate school I remember seeing petunias that looked like this, and they had a corn gene in them.” [Laughter.]

He took a sample—I think it was in front of the train station in Helsinki—and took them back to his lab and ran a test, and it was like, “Yep, they have that corn gene.”

That gene never got approval; they never went through the regulatory process that we have for genetically modified organisms, and now Europe and the U.S. is ordering all of them to be destroyed because they are classified as a biohazard. [Laughter.]

Q. It’s very interesting. For me the funniest part: Until I saw this story, there has only been one petunia I ever really fell for in a big way, and I don’t know how long ago—not 10 years ago, but not the last 3 or 4 years. Anyway. I haven’t really seen it since, but it caught my eye because I am an orange person. [Update: It was 2011, and the story is here.]

It was called ‘Papaya’ [above] and in the Potunia line from a particular breeding company, and it was so distinctive, like the inside of a papaya color. I just loved it, and grew it for a year or two and then it disappeared. I wondered why it was orange, but didn’t know it has corn genes, and sure enough it’s on the list of all the naughty petunias.

This is really a regulation issue, they are saying, not a safety issue, because petunias aren’t a food or fodder crop that we are either eating ourselves or feeding to animals, but they broke a rule by not filing that they were doing this. It’s a regulatory issue.

A. I think most people would say that 1, we’re not eating it, with the orange pigment—and 2, it’s not like with corn where they put these insecticidal genes in it, and that might have impacts on the environment. An orange pigment in a flower seems to have little safety concerns or larger ecological ones.

In Europe it will probably be very difficult to get deregulated. In the U.S., our rules are laxer on that. So yes, they probably could have gone through the proper channels and got this released legally.

What’s interesting is that the trait popped up in like four different companies’ breeding at around the same time, and they are all saying, “We have no idea where it came from.” [Laughter.]

Q. [Laughter.] [Above, two presumably GMO varieties Joseph saw recently for sale in a nursery.]

A. You have to wonder: You see this crazy new color and everyone’s like, “We don’t know, it sort of just arrived.” It will be interesting to see. Everyone’s just saying, “Gosh, we have no idea how it happened; we’re destroying them all.”

It would be interesting to know how the gene moved from a university research program into all these different petunia-breeding programs around the world, actually.


Q. Interesting to do the forensics—maybe it could be the next season of ‘Sherlock,” with Benedict Cumberbatch. They can investigate it.

A. [Laughter.]

Q. What a spokesperson for the USDA said in one of the more recent stories is that, again, since it’s not a risk to human health since we don’t eat them, they’re not asking consumers who might have an orange petunia in their garden, or retailers that have them in stock, to destroy them this season. They’re just saying that breeders, growers and retailers should “voluntarily withdraw GE plants from distribution,” and destroy them. It’s not like you the gardener is breaking some law or has something dangerous. It’s a compliance thing, not a safety thing.

Then I read a later story I couldn’t even understand:

“A spokesman for USDA-Animal and Plant Health Inspection Service-Biotechnology Regulatory Services (USDA-APHIS-BRS) says, ‘the exact genetic identification has not been confirmed.’”

They’re still testing, in other words—and not just the corn thing, but what else is going on in there. Because they are not all exactly the same, and there is a whole list as you say from multiple breeders. [Update: Testing continues to see if all the orange petunias have the corn gene, or something else is at work, and also to test other colors of petunias, some of which have also been found to be affected.]

And they say: “…we are advising organizations to test for the presence of Cauliflower mosaic virus 35 S RNA promoter…” and it’s like in language that’s not even English, so I am like, “What?” What does this all mean?

A. What that means weirdly is that in the U.S. for non-food crops we don’t actually regulate genetic engineering per se. So if it’s just the corn gene, you could insert the corn gene and release it with no approval, and that would be perfectly legal in the U.S. You couldn’t do that in Europe.

But what they usually do is a combination of the corn gene and this Cauliflower mosaic virus that you just mentioned, and that virus gene is regulated. If they have the corn gene but not the virus, it might be OK, but if they have the viral gene plus the corn gene then it definitely is not.

Q. Oy, vey, Shirley—I’m telling you. My head is spinning over here! [Laughter.] This is the crazy intrigue.

A. What I think is interesting is because like you just said that technically they could recreate this if they just avoided using the viral DNA and used the corn DNA—you could recreate it legally. But I bet a lot of companies are watching the reaction to this, because there really hasn’t been a lot of public outcry that I have noticed, anyway.

And they may be saying, “Well maybe we’ll just wait a couple of years and then we’ll do this”—to make essentially the same thing but just tweak it to avoid the regulation, and release it. It will be interesting to see if this opens up a brave new world in petunia breeding.

Q. It’s a little bit of a test case. Or in other breeding, for that matter—they could use this case as a standard. Joseph, I love the fact that I finally found someone who’s as interested in kooky, strange things as I am. [Laughter.]

  1. KarenMarie Minnis says:

    I have always loved hollyhocks–as a young girls, my sisters and I would pick blossoms from a neighbor’s garden, and turn them into ‘dancing dolls’ by adding floral wire arms and tiny heads of modeling clay. I’m currently re-working some of my garden beds, think I’ll add some hollyhocks, just for fun.

  2. Marie Labrie Nickerson says:

    I work in an island garden, zone 5b. As a historic garden, we have been planting heirloom varieties and Botanical Interests carries althea rosea “Indian Spring” which has been averaging 6-7 feet tall, with no staking. Because so many plants have been introduced to this garden over many years, we have quite an eclectic collection of hybrids with unpredictable colors. They, and the poppies are one of the biggest draws to the garden. Even the patch growing wild by the sea is awesome. Joe spoke for our group of Master Gardeners this spring… had I only known his love for my favorites, the hollyhocks! Visit Celia Thaxter’s Island Garden FB page for more lovely photos.

  3. Ann says:

    I had completely forgotten about these lovely flowers, but now remember them in my grandmother’s garden back in the 50s! Thank you for reawakening treasured memories! I will be studying the seed catalogs Joseph mentioned and can’t wait to get started!

  4. marty says:

    have enjoyed and grown hollyhocks my entire life. Especially the dark ones that Thomas Jefferson liked. My partner thought those dark ones were evil looking !!! But I like all of them. Thanx for the additional info

  5. Chris Evans says:

    I stole some Hollyhock seeds while on a volunteer vacation in New Mexico in fall 2014. Back in Southwest Virginia, I forgot to plant them until fall 2015. The first year, 2016, there were beautiful leaves only. This year, 2017, the flowers were magnificent and grew to be 10 feet tall. Ultimately, the plant has succumbed to rust so it probably was the common “rosea” type. After reading this flower porn article, I have a plan to cut back and save a few seeds, just in case.
    I would like to attach a photo. Is that possible?

  6. Kathy Purdy says:

    I have grown Alcea ficifolia in the past. Not currently growing any, but I think I want to try that Alcea hohenackeri. Lots of members of the Mallow family get rust, and it doesn’t seem to be bad on any of them this year. We have had some pretty humid days, but we’ve also had frequent rain, and I wonder if most plants get rust when they’re not getting optimum growing conditions. Maybe they just like more moisture than they usually get? Just thinking out loud here.

  7. Carolyn says:

    I have grown hollyhocks. I didn’t have rust problems even though I garden in central Maryland but the flowers and I surrendered to the sawfly larva. Sigh.

  8. Judy says:

    I found this information very interesting–bought 3 plants last year in a garden center–the plants didn’t grow much and didn’t reappear in my zone 5 garden this year–guess I didn’t approach this correctly.

  9. Barbara Bullemer says:

    I adore the hollyhocks, I have the Alcea rosea from my mother, I would love to have a a group planting of a few different varieties.
    Thanks for this podcast I am ordering some seeds to plant now.

  10. Nancy Sciarretta says:

    Began the nearly black ‘nigra’ from seeds last year. This year I’ve got incredibly tall plants that have blown over from our heavy rains. Not sure how to keep them propped up but do love the look of such a large neutral color in the garden.

  11. Kat Springer says:

    I was lucky to find a small patch of white hollyhocks when I bought my house. I have no idea what kind they are, but they are just lovely. I’ve been thinking about adding another color. Please include me in your drawing. Thanks!

  12. Joan Adams says:

    I noticed a plant in my garden that I didn’t plant and then recognized it as, I believe, Alcea rosea perennial. I’ll try to harvest the seeds this summer. I was very excited to see it appear in bloom. I only recognized it after reading your conversation with Joseph. Thank you.

  13. Mary lou Spencer says:


    Kind of a different query:

    Can you recommend a really good brand of gardening pant and short? Jean cut-offs are just too stiff and lighter cottons don’t hold up. I thought I could surf the internet for days or save myself some time and ask you.
    Thank you,
    Mary lou

    PS. After discarding a couple of pairs of gardening knee pads, I’ve now discovered mason’s knee pads, much sturdier and available in the tool department.

    1. margaret says:

      Hi, Mary Lou. Truth be told I always wear stretchy former yoga pants or the equivalent, because I cannot stand the stiff stuff, either. But they are not cool (and I never wear shorts, but that’s just a personal preference, and most friends do). One gardening friend is now using Craghoppers brand of outdoor-gear insect-repellent pants and shirts (treated with permethrin), sales of which benefit National Geographic, apparently…but I don’t know how I feel about that stuff. But I do think the outdoor stores like EMS that specialize in durable stuff might be worth exploring if there is one near you. Wish I had a good answer. I am comfortable in my stretchy pants, but often overheated in the warmest weather.

  14. Carol says:

    Bought 2 hollyhocks from different nurseries this year. No flower stalks so not annuals but I don’t know if they’re perennial either.

  15. Celia Brown says:

    Well, here in Georgia I’ve really struggled to keep hollyhock alive with the major rust pronlem. Have actually found them offered at discount in bare root plastic packages. Look for in early spring for sale. Of course more choices as seed. Good luck growing in Virginia. ……I’m a transplanted Texan where I watched my grandmother grow beautiful plants and of course make dollies for me!

  16. Rhody says:

    I did but not any more, too much rust. And larvae from a corm borer, I think. One year I cut the stem along its length, squashed all the larvae, and then tied up the stem with raffia. As much as I love hollyhocks, I’m not doing that again. Please count me in on the book. Rock Gardening, please.

  17. Susan says:

    I grew hollyhocks a very long time ago, maybe 25 years ago. Yikes where does the time go. Anyway I didn’t start them from seeds of that I’m sure. I have no idea which they were either. They were beautiful. We moved and that is one of the reasons I didn’t plant them again. I was also looking to plant mostly perennials at the time. Now that I know they have some that are perennials I’ll try them again. Hope they like Virginia because we are moving there too.

  18. Christine Semidei says:

    Thank you for your informative article on Hollyhocks. I live in Brooklyn, New York, zone 7, and it just so happens that in my neighborhood there is a small garden with you guessed it Hollyhocks! I waited patiently for the seed pods to develop and dry on the plant. When I walked away with those precious seeds, I felt like I was so privileged to have the knowledge of the power that was contained in those seeds. So this is my first attempt at sowing Hollyhock seeds, and with much care and appreciation, and God’s help, up came the little shoots. They are only about 1″ high, but they mean the world to me. I’m looking forward with whatever patience is needed to see them to maturity. P.S. Patience, that is one of the most valuable teaching lessons I’ve learned from my garden.

  19. Nickolas Paullus says:

    I grow Hollyhocks. They seem to perpetually go to seed and pop up in a new place. I live in an alley cottage, and the fence on the east side of the alley has a few maroon/wine colored hollyhocks that are about 9 feet right now. Luckily, those are the most vibrant and striking of colors in the garden right now… so I’m loving it.

    And those are unfertilized, barely irrigated, and not staked… just to note. Not much rust either (Colorado gets very little summer humidity)

    -N (Littleton, Colorado)

  20. Nickolas Paullus says:

    One additional comment is that Japanese beetles seem to love the Hollyhock blossoms (not the greenery) in the area, but avoid mine because they are fringed by delphiniums and larkspur which the beetles are notoriously averse to.
