Let's Argue About Plants

It doesn’t matter whether we’ve been naughty (Danielle) or nice (Carol) this year—we’re still going ahead and adding plenty of plants to our wish lists. We’re talking about trees that we’ve had our eyes on for months and a perennial that shines in spring, summer, and light up electric yellow in fall. Many of these plants will be new to nurseries this coming spring, while others have been around a bit longer. If you’re wondering what plants the hosts of a podcast all about plants dream and drool over, tune in today. Because visions of sugarplums don’t dance through our heads…but visions of coneflowers do!

It’s the most wonderful time of the year! No, not because it’s the holidays, because it’s the annual Q & A episode here on Let’s Argue About Plants. When we put a call out each year asking you, our faithful listeners, to send us your most pressing questions about plants and gardening, we never know what to expect. But boy did you deliver this time! We had so many questions roll in that we had to create a spreadsheet just to keep track. In today’s episode we’ll answer as many of those queries as possible, and in some cases, reach out to our colleagues in horticulture to respond (because let’s face it, we don’t know everything). Tune in to see if your question—or a question similar to yours—is answered and what we had to say about cottage gardens and whether or not you may need therapy because of a plant addiction. Expert guest: Award-winning landscape designer Jay Sifford is the owner of a design firm located in Charlotte, North Carolina. He is an author for Fine Gardening magazine with a new feature out i

Depending on where you live in North America, fall in the garden can bring anything from a flood of vibrant color to just the slightest hint of a new hue. Here in New England, we’re pretty lucky to get an explosion of autumnal colors most years. But today we decided to talk about those plants (trees, shrubs, perennials, and yes—even an annual) that can be counted on to express THE most shocking color when the temps cool down, regardless of geographic location. We realize that some of you live in warmer climes, so we have included a few fall-bloomers that will put on a show into Zone 9, as well. If seasonal depression has started to set in, beat back those impending winter-blues by listening to this episode and then head to the nursery to pick up some fall stunners—it’s not too late! Expert guest: John Forti is the executive director of Bedrock Gardens in Lee, New Hampshire and author of The Heirloom Gardener: Traditional Plants and Skills for the Modern World.

They're creepy and they're kooky. Mysterious and spooky. They're all together ooky. Nope, it’s not the Adam’s Family, it’s the array of wicked plants on today’s episode. It’s Halloween season so we’ll be talking about an assortment of plants that are spiky, darkly pigmented, stinky, or perhaps even the most wicked of all: invasive. But don’t think every perennial or tree on this episode is unworthy of a spot in your garden, some are actually quite lovely landscape specimens. Can a plant truly be frightening? Sure it can—just ask Seymour Krelborn. For further reading on wicked plants, check out this book by Amy Stewart.

We very pleased to bring you a special episode of Let’s Argue About Plants today, featuring an interview with Douglas Tallamy, PhD. Several months ago, Christine Alexander, digital content manager for FineGardening.com, sat down with the famed professor of entomology and wildlife ecology at the University of Delaware to discuss how plants can save our planet. Tallamy has spent his life’s work researching the impact of nonnative plant species on the environment with his fieldwork playing a critical role in solving the mystery of the plummeting insect and bird populations seen over the past 50 years. Despite the seemingly larger-than-life problems we face, Tallamy insists there are ways average gardeners can help save our ecosystems. Within the interview we get answers to the questions gardeners want to know like, “Should we be planting only native plants?” And “What are keystone species and why should I be filling my landscape with them?” Tallamy’s message is sometimes misconstrued, especially when it comes to

What’s not to love about sedums? They’re drought-tolerant, they attract pollinators, and they flower later in the season when not much else is going on in the garden. But they also have their drawbacks—namely a proclivity to splay open (we’re looking at you Autumn Joy) and look rather awful in some cases. But rest assured that today we’re talking about sedums that maintain a compact habit (whether they’re an upright or ground cover type), still sport gorgeous flowers, and thrive in terrible conditions. If you have full sun, lean soil, and hate plants than need a lot of pampering, then this episode is for you.  Expert testimony: Sandy McDougle is the founder and owner of Sandy’s Plants in in Mechanicsville, Virginia.   Danielle’s Plants 'Boogie Woogie' sedum (Sedum ‘Boogie Woogie’, Zones 3-9)  'Night Light' sedum (Sedum 'Night Light', Zones 3-9)  'Plum Dazzled' sedum (Sedum rupestre ‘Plum Dazzled’, Zones 4-9)  ‘Carl’ sedum (Hylotelephium telephium ‘Carl’, Zones 3-9)    Carol’s Plants ‘Matrona’ sedum (Hylotelep

What gardener doesn’t like something a bit out-of-the ordinary, right? Especially when it’s a plant that puts on a serious show as the final curtain call is happening. Today we highlight some of our favorite unusual fall perennials, options that are interesting cultivars of a genus you may know, and weird oddballs you’ve likely never heard of. Just a heads up that we may have cheated a teeny, tiny bit and thrown in a shrub or even a tender perennial to keep you on your toes. Regardless the plants you’ll hear about on this episode are all exceptional autumnal stars that will stop garden visitors in the tracks to ask, “What on earth is that?” Expert testimony: Matt Mattus is the author of two books: Mastering the Art of Flower Gardening and Mastering the Art of Vegetable Gardening. He gardens in Worcester, Massachusetts.   Danielle’s Plants ‘Snow Fairy’ blue mist shrub (Caryopteris divaricata 'Snow Fairy', Zones 6-9) ‘Lady in Black’ calico aster (Symphyotrichum lateriflorum ‘Lady in Black’, Zones 3-8) ‘Golden A

Nearly everyone can grow tropical plants outdoors during the summer months, but when the first frosts are forecasted gardeners in colder climates know there will be some tough decisions ahead. Which plants will be moved to those coveted spots by a south-facing window for winter? Is it worth the trouble to dig dahlia tubers and overwinter them, or should you just start over from scratch with newer, prettier varieties next year? Should you (once again) convince your significant other to don oven mitts, help you relocate your cherished collection of agaves indoors, and cohabitate with those dangerously spiky beauties until spring? OK, that last question might only be on Danielle’s mind, but tune in to this episode to learn about the many ways our hosts have found to get their favorite tender plants through the coldest months, and why it is worth the effort. Expert testimony: Chloë Bowers is a professional gardener and landscape designer based in Newtown, Connecticut.   Danielle’s Plants ‘Escargot’ rex begonia (B

They’re tough, they’re hardy, they thrive in almost any location. So, why don’t we love them? Give this episode a listen to hear about plants that have a ton of good attributes, but just can’t bring ourselves to draw a heart around them. It’s easy to ask gardeners what plants they hate—we all have long lists of inferior perennials, trees, and shrubs that are weak or have unruly habits making them deserving of our ire. But, what about those plants that haven’t done anything to get themselves “do not buy list?” Turns out Carol and Danielle aren’t the only ones with these complicated feelings, today’s expert has similar thoughts.   Expert testimony: Andy Pulte is a faculty member of the plant sciences department at the University of Tennessee in Knoxville.   Danielle’s Plants 'Peachie's Pick' Stokes’ aster (Stokesia laevis 'Peachie's Pick', Zones 5-9) ‘Persian Ruby’ daylily (Hemerocallis 'Persian Ruby', Zones 3-9) Veronica (Veronica spicata and cvs., Zones 3-8) Blue rug juniper (Juniperus horizontalis 'Wiltonii'

We all know and love parsley, sage rosemary, and thyme. And then there’s sweet basil which is perhaps the queen of all the herbs. But what about those herbs that are just as tasty—or attractive—but don’t get the same accolades? For those unsung heroes of the herb garden, we put together this episode. You’ll hear about a deliciously spicy lemon basil, an elegant edible flower with brilliant orange blooms, and a marigold that resembles a mint. There are a mix of herbs grown for ornamental and edible purposes and some that can be put firmly in both those categories. Looking to spice up your garden with something a bit out-of-the-ordinary? Then give this latest episode a listen.   Expert testimony: Sue Goetz, author of A Taste for Herbs and Complete Container Herb Gardening, is a garden designer and garden coach based in Washington state.

According to NASA Earth Observatory, one-third of the United States experienced some level of drought in 2020 and 2021 was much the same. This pattern of extended dry weather is sadly becoming more and more of the norm. We recently did a feature in Fine Gardening magazine highlighting a series of drought tolerant woody plants from around the country in our regional pages and that got Carol and Danielle thinking about which trees and shrubs are their favorite water-wise selections. Listen to today’s episode for ideas on these backbone plants that won’t require much, if any, intervention from the hose. Special guest: Amy Galloway is a horticulturist at the Lady Bird Johnson Wildflower Center in Austin, Texas.

The original title of this episode was, Big and Bold Plants for the Back of the Border. But between the length and the tongue-twister alliteration, we shorted it a bit for promotional purposes. However, on today’s program you’ll hear all about plants that really stand out in the last row of the garden choir. These perennials and shrubs are tall, yes. But they have so much more going for them than simply their towering presence. The featured plants offer a grounding and bold backdrop for your garden beds, but don’t flop all over the place. Some have excellent texture, others bodacious blooms, and a few even provide that beefiness during all four seasons. If you’re looking for something to enhance—not just fill in—the back of the border, give this episode a listen. Special guest: Courtney Olander, landscape designer from Seattle, Washington.

When late May and June hits, we can’t help wandering out into the garden with a pair of shears in hand. Bringing fresh flowers into the house seems like a seasonal rite of passage for most gardeners (at least those that don’t have allergies). But it can be a hard to cut those precious blooms and take them away from the landscape. That’s why today we’re talking about plants (perennials, annuals, and even shrubs) that we grow specifically for their flower-power. These options provide plenty of blooms for the garden AND the vase, and that’s why they’re our favorites. We span the color spectrum as well, with recommendations for every hue imaginable. And, we even have several selections that are deliciously fragrant. If you’re looking to add some cutting garden oomph to your beds and borders, give this episode a listen.   Special guest: Christine  Alexander, digital content editor for Fine Gardening.com

Is there anything ground covers can’t do? They are useful in problem areas like steep slopes, under trees and shrubs, and in spaces that need erosion control. They also reduce maintenance by enveloping areas that would ordinarily need a boatload of mulch to keep weeds at bay. Now, not all ground covers play nice. Some species will not only cover bare ground, but they will choke out neighboring plants. But that’s not the plants we’re talking about today. We’re focusing on ground covers that will spread out thickly, but politely, and smother out any potential weeds in the process. We discuss options for sun, shade, and even drought tolerant selections for those truly hellish spots. And in case you think we’re too East Coast centric, today’s expert calls in from California to offer up some plants that thrive in the Western half of the country. Expert testimony: Fionuala Campion is the owner and manager of Cottage Gardens of Petaluma in Petaluma, California.

Always give a gift that you yourself would like to receive. That’s excellent advice when it comes to life-- and as gardeners, we can extend that sentiment to giving plants as gifts. Ask yourself: what plants would I like to get as a gift? We had a lot of fun on today’s episode, imagining the scenarios in which we’d give our friends, neighbors, or even strangers particular plants that would convey our feelings of happiness, sympathy, or just pure joy. Need a wedding present that’s truly unique this season? Well give a listen to our suggestion for a perfect small tree that will grow right along with the love that the couple has for one another. OK, we promise, the other suggestions aren’t nearly as sappy.   Special guest: Scott Endres is a designer and horticulturist at Tangletown Gardens in Minneapolis.

Little kids have Christmas. Gardeners have spring. To us, this is the most wonderful time of the year. And with the start of the season, comes those inevitable trips to the nursery. In an effort to not max out their credit cards, this spring Carol and Danielle are making shopping lists of plants that they will be on the hunt for. These species are going to fill a particular need or want in their gardens, and they might do the same for you. Listen today to see what our hosts are dreaming of adding to their beds and borders. Special guest: Kim Toscano is a horticulturalist based in Stillwater, Oklahoma. She previously hosted Oklahoma Gardening, a weekly PBS television program produced by the Oklahoma Cooperative Extension Service.

Yes, that’s right: plants can solve problems. Maybe not problems like those noisy neighbors next door or your husband failing to replace the toilet paper roll, time and time again. But plants can solve problems like a barren patch of garden under a shallow-rooted tree, or a lack of pollinators in your yard. Today’s array of fantastic perennials are plants that can address conditional or pest problems that you may be struggling with. Need a vole-proof, pollinator magnet? We’ve got one. Need a plant that will deter teenagers from driving on your lawn? We have that too. Listen now for more plants that you’ll need to add to your list of must-haves this year.

They’re often called the “exclamation points” of the landscape, drawing attention in a not-so-subtle way. Of course, we’re talking about columnar (AKA fastigiate) plants and today we’re highlighting some of the best options. Skinny plants are invaluable for several reasons other than their ability to catch the eye. They also have a small footprint which makes them ideal for siting in narrow places including along the side of a house or in a tight spot between established plants in a border. Their habit is clear, concise, and always intriguing. Along with our guest, Richie Steffen from the Elizabeth C. Miller Botanical Garden, we’re discussing skinny trees, shrubs, and even a few perennials that will give your garden an instant focal point like no other. Special guest: Richie Steffen is executive director for the Elisabeth C. Miller Botanical Garden in Seattle, Washington.

Even though there’s still snow on the ground for many of us, warmer weather is most definitely on our brains. So today we’re going to be talking about native plants that put on a spectacular show in spring. And, although we’re a podcast based out of New England, the plants we decided to talk about have an extensive native range (even into Texas!). There is an exquisitely fragrant perennial, a self-sowing ephemeral, a delicious edible, and several trees and shrubs that bloom so prolifically in April, May, and June you’d think it was their only job. Want a list of nearly a dozen native plants that are show-stoppers? Then press play now!  Special guest: Nancy J. Ondra is a garden photographer, author, freelance editor, and licensed seed seller who lives and gardens on four acres in Bucks County, Pennsylvania.

There’s no reason to tell everyone how great ‘Brandywine’ tomatoes are because everyone already knows! And the same goes for ‘Blue Lake’ green beans or ‘Hot Wax’ peppers. We all know these names because they are great varieties that vegetable gardeners have relied on for decades. Yet, there are a bunch of lesser-known veggies that deserve the same praise, but their PR agents aren’t the best. On this episode Carol and Danielle are taking the time to call out some of the unsung heroes of their veggie gardens. These are varieties that have proven themselves over and over, but their names aren’t generally well-known in edible circles. We’re hoping to change that after today!
