STEM Tuesday– Plants– Interview with Rebecca Hirsch

Welcome to STEM Tuesday: Author Interview, a repeating feature for the last Tuesday of every month. Go Science-Tech-Engineering-Math!

Today we’re learning with Rebecca E. Hirsch, a science writer, educator, and author of more than 90 books for young people. Her 2024 book A Deathly Compendium of Poisonous Plants: Wicked Weeds and Sinister Seeds is a delightful collection of science, folklore, true crime, quotes, and more, all about poisonous plants!

 

Andi Diehn: How did you get interested in poisonous plants? (Should we be worried?!)

Rebecca Hirsch: Great question! And there’s no need to worry, but now you’ve got me laughing! This book grew out of research I had done for a previous middle grade title, called When Plants Attack: Strange and Terrifying Plants. When I was researching that book and deciding what plants to feature in it,I came across a lot of poisonous plants. But poison wasn’t really the focus of that book, so I set most of those plants aside. Nevertheless, the seed had been planted. Several years later, I began to imagine writing a creepy, gothic book that looked at the science and history of poisonous plants.

 

AD: I love that you combine mythology, quotes, history, and science – why include all these elements?
RH: Poisonous plants have such fascinating back stories! People have long used these plants for medicine, as well as for darker acts like warfare and murder. As a science writer, I knew I wanted to share the science of these plants—facts about how and where they grow but also how they interact with and harm the human body.  But I made the decision to start each chapter with an intriguing historical quote and whatever dark and fascinating stories I could dig up. My goal was to entertain readers in addition to educating them. I wanted them to see how captivating and complex these plants are.
AD: Many poisonous plants are useful as well as deadly. Does this make botany even more interesting?

RH: Definitely! Most people think of plants as boring, kind of like green statuary. But plants are actively struggling to survive, like all living things. Plants have very effective ways of fighting back against anything or anyone that tries to eat them. In the botanical world, the most common self-defense tactic is poison. Plants are master chemists. They are very good at concocting nasty chemicals, and some of these chemicals can make animals and people very sick.

 

AD: The chemical explanation of how different poisons work is fascinating. Do you think poison loses some of its fear factor when we learn about why it does what it does?
RH: For me, learning about these poisons made them even more terrifying. It’s alarming to discover how the deadliest of nightshades—belladonna, for instance—can unleash havoc on our brains and bodies. Or how ricin from castor beans can act like a wrecking ball to our vital organs. Or the way cocaine or opium can hijack our brains and produce crippling addiction.
I do think the fear factor can be a good thing, because it can protect us. At least, that’s my hope. I repeatedly encourage readers to steer clear of nearly all of the plants in the book.

 

AD: In a way, this book redefined my definition of poison when I read about peppers. I eat peppers all the time and never thought of the hot ones as poisonous. How does this show that even things we encounter every day can be harmful in large quantities or if used wrong?

RH: Oh yes, chilies are definitely poisonous. These plants manufacture their poison—a chemical called capsaicin—as a way to prevent mammals, including humans, from eating their fruits (the peppers).

Here’s a personal anecdote about chilies: A number of years ago, my garden produced a bumper crop of jalapeños, and I decided to dice and freeze my harvest. One evening, I pulled out a sharp knife and a cutting board, and went to work on a pile of shiny green jalapeños. Foolishly, I did not wear rubber gloves. When I was finished, I had a heap of diced jalapeños—and poison all over my hands. My skin burned, especially under my fingernails. Then I rubbed my eye. Now my eye was stinging and watering. I soaked my hands in milk and yogurt—dairy products are a remedy—but it didn’t help. I ended up staying awake half the night, unable to sleep because of the pain.
By the way, jalapeños measure about 5,000 on the Scoville scale, a measure of chili hotness. One of the chilies mentioned in my book, a variety called Pepper X, has a Scoville rating of 2.7 million! Jalapeños are quite mild in comparison, but even they can be painful in large quantities!

 

AD:What is your research process like? How do you find all the great stories included in your book?

RH: I love the research process. I can get lost in it! My process is to start general and then get more specific. I usually begin with general internet searches, and I also track down books that are written for a general audience. I use the public library to find nonfiction books on my topic, and I use my library’s online research tools to track down magazine articles. When I’m reading a book, I’m flipping to the back pages constantly, studying the source notes and bibliography. I want to see what sources that author used in their own research, so I can follow up with any promising sources.

As I go deeper on my research, I start moving into more scholarly works. For A Deathly Compendium of Poisonous Plants, those works included toxicology textbooks, scientific research on the action of poisons in the body, and scholarly books about the history of poisonous and medicinal plants. Google Scholar is my go-to place for tracking down scientific papers. My state university’s library system is where I find scholarly books. As I’m reading those scholarly papers and books, I’m also studying their bibliographies, and then I continue tracking down more sources.

 

AD: I love the artwork and design of the book. Did you have input or was that entirely up to Eugenia Nobati?

RH: I’m so glad you like it! The design was a part of the book concept from the beginning. When I pitched the idea to editor Shaina Olmainson, who was formerly at Zest Books at Lerner Publishing, she immediately got on board with my vision for the book having a creepy gothic vibe. Lerner’s design team also got behind the idea in a big way.

The Lerner team brought on Eugenia Nobati to illustrate. She had previously illustrated picture books for Lerner, but Eugenia also had experience creating darker, creepier art. Eugenia dove enthusiastically into the project. Her illustrations look like they had come out of an ancient laboratory notebook, with coffee rings and dark stains marking the pages.

 

AD:Do you have a favorite poison? (Not to use, but to learn about!) What is it and why?

RH: Mandrake was a lot of fun to write about. I had to force myself to stop working on that chapter and move on because I was so enchanted by that plant. It has such a rich and twisted folklore. In ancient and medieval times, people thought mandrake root resembled a naked body. They associated the plant with sexual potency and imagined that it had all sorts of magical powers.

 

AD: Did you find yourself being more careful about what you ate while writing this book?

RH: Truthfully, I’ve long been careful about what I eat. When I was a kid, I played outside an awful lot, and my parents impressed upon me never to nibble anything unfamiliar outdoors. When I was a teenager, I developed terrible food allergies, so that made me even more cautious. Alas, the chapter on allergies was written with a lot of firsthand experience.
I tried to pass along a sense of caution to my readers. Just because a plant is pretty or its berries look inviting, that does not mean it is safe to eat.

Interview with Jeanne Birdsall, award-winning author of The Library of Unruly Treasures!

Jeanne Birdsall’s THE PENDERWICKS is as highly acclaimed and beloved as a middle-grade series can be, earning the National Book Award and becoming New York Times bestsellers. With her newest novel, THE LIBRARY OF UNRULY TREASURES, she creates a new world: one of tiny, winged creatures called Lahdukan and the adventures a girl named Gwen has with them in a library outside Boston. It’s a wild, fun, and heartwarming ride that is sure to delight Penderwicks fans and new readers alike.

Read below to discover the inspiration for this new book, thoughts on Lahdukan pronunciation and (incredible!) art, and the real Pumpkin the dog(s) in Jeanne’s life!

Book cover of THE LIBRARY OF UNRULY TREASURES by Jeanne Birdsall

The opening of THE LIBRARY OF UNRULY TREASURES grabs readers with a series of diary entries that tease some of the magic to come. When did you decide to open the book like that, and what are you hoping readers will glean from it?

I knew I’d have to open the book in 1860s Edinburgh, if only to justify the research trip I took to Scotland. That’s only kind of a joke. Truly, once I’d wandered the neighborhood where my diarist lived, she became too real to be shoved aside as mere backstory.

I thought it would be fun for the readers to know more than Gwen does at the beginning of the story, to have them impatient for her to meet the Lahdukan. When she finally does, the reader already knows the Lahdukan are real and thus can enjoy watching Gwen become convinced. From that point on, the reader knows only what Gwen knows. They can be puzzled together, and I hope they are. I like a bit of a mystery.

Gwen is a character readers immediately pull for—what was the process like of creating her? Was she fully formed from the start, or was it a longer process, and how did Matt Phelan’s interpretation of her (and the other characters!) come to be?

I knew Gwen right away. It took me a while, though, to work out what made her who she was—both despite of and because of her rotten parents and lonely childhood. And even longer to figure out how to explain her past without a lot of exposition. I wanted the reader to understand how difficult it had been for Gwen, but without piling on too many gruesome details.

Matt illustrated a picture book of mine, Flora’s Very Windy Day, so I knew that our instincts and visual aesthetics were in sync. He got Gwen right away. (And gave her freckles. I pretend this was in honor of my freckles, but it may have been a coincidence.) We had to go back and forth for a while with Pumpkin, but that was my fault. My original text made her sound like a mythic monster, a tiny griffin with impossibly mismatched parts. Matt’s Lahdukan are masterpieces. Their combination of goofiness and dignity is right there in every painting. And the Lahdukan in flight! There’s one spread of them aloft inside the Isabella Stewart Gardner Museum that makes me catch my breath every time I see it.

The detailed worldbuilding of the Lahdukan is such a joy to uncover in the book. You mention Mary Norton’s delightful The Borrowers as an inspiration for these tiny, wondrous creatures, but did you have any other influences on this world?

The Borrowers are an obvious reference point. Not only were the books written during my childhood—we were allreading them—but Beth and Jo Krush, the illustrators, lived in my neighborhood, a mile down the road. But the Lahdukan were woven from dozens of myths and stories, enriched by my fascination with Scotland, particularly the Highlands. Some of this came because of my Scottish blood, but lately I’ve been re-reading T. H. White’s The Once and Future King. He goes deeply into the Scottish Gaels (Gawaine and his peculiar brothers) and their resentment of the English. This must have lodged in my brain years ago, to come out now.

Plus, I’ve always wanted to be able to fly, haven’t you? The closest I could get was bestowing eagle wings on my Lahdukan.

Pumpkin the dog is a force throughout the book, and you mention in the introduction that you can’t write without a canine companion. Was Pumpkin always such an integral character, or did her role change through the drafting process?

Pumpkin was always going to be important to the story, but not being satisfied with mere importance, she upped her own role until she was vital. Just like my real dogs.

[Editor’s note: to see pictures of Jeanne’s own dogs, visit her website!]

I appreciated the pronunciation guide at the end of the book and had so much fun with the Lahdukan names and background. Is that something you had thought through while writing and sounding out these splendid details?

No, but I should have! Because I don’t like reading my own writing out loud and I don’t listen to audiobooks, I didn’t think about it along the way, just merrily dreaming up names and words. It was only toward the end, when my own husband still couldn’t remember how to say Abarisruk or Zarakir, that I realized I’d need a pronunciation guide.

Although I don’t listen to audiobooks, I hope people will listen to this one. By an incredible stroke of luck—or maybe magic—we found the perfect narrator. Sorcha Groundsell grew up on the Isle of Lewis, one of the Outer Hebrides, west of Scotland and close to the Isle of Rùm, where the Lahdukan lived a thousand and more years ago. (See? Magic!) Her voice is gorgeous—light, quick, musical—exactly what the story calls for. Just wait until you hear her as the Lahdukan.

Do you have any other adventures in mind for Gwen, Pumpkin, and the Lahdukan, or are you returning to other book worlds (or elsewhere!) next?

I have dozens of other adventures in mind, going forward and backward in time. But speaking of time, alas, I don’t have enough of it. The Penderwicks took twenty years of my life, and almost certainly I don’t have twenty more to spend on another series. Where I’m headed next is still a bit fuzzy, but there will be pie and a dog, and I’ll have to learn some Italian.

Finding Home Again: 5 MG Books About Moving and Identity

Two Black girls stand confidently on a beach with a purple-blue sky and knit-textured backdrop. One wears overalls and sneakers, the other wears a skirt and boots with sunglasses. The title is in bold white handwritten letters.

Unlike most kids I knew, my family moved almost every year. New town. New school. New hallways to navigate. And nearly every time, I was the only kid of color in the room. This not only left me feeling unsure about who I’d sit with at lunch, but unsure about who I would have to become in order to fit in.

Why it Matters: During the summer months, many kids are bracing for that intense kind of transition. Some are moving across town. Some across states. Some across oceans. They won’t just be starting over. They’ll be rebuilding their sense of identity and belonging from scratch. A process that can be uncomfortable, disorienting, and at times, deeply lonely.

Go Deeper: These five middle grade books are for readers going through that kind of change. Kids of color, kids from other countries, kids navigating new spaces that don’t quite feel like home yet. These stories reflect their journey and remind them that “home” is a place within themselves.

When Meilan’s family leaves Boston’s Chinatown for a mostly white town in Ohio, she loses more than her home. At her new school, her principal even changes her name to “Melanie” without asking. Meilan splits herself into pieces just to survive, but ultimately must decide which version of herself is true.

Perfect for: readers who’ve been renamed, mispronounced, or asked to shrink themselves to fit in.

In Closing

You know I love to highlight books that aren’t afraid of the hard stuff. And at the heart of every move is a kid asking tough questions like: Who will I be in this new space? Will anyone see me for me? Will I ever feel like myself here?

It can make kids feel like the ground is slipping beneath them. I hope these stories help them find home again, not in a specific place, but in who they are.
