Super Cool Plants - Formerly Known as Let's Argue About Plants

While the Fine Gardening team is busy exploring the Philadelphia Flower Show, we're taking a moment to look back at some of the most insightful and inspiring conversations we've had on Let's Argue About Plants over the past year. In this special episode, we're revisiting standout moments from interviews with horticulturists, garden designers, and educators who have shaped the way we garden.

You'll hear from Stacie Crooks, a self-taught garden designer from Seattle, as she shares how she got her start in horticulture. Jay Sifford, a North Carolina-based designer, discusses his artistic influences and how pop culture can inspire transcendent garden spaces. Irvin Etienne, a public horticulturist at Newfields in Indianapolis, reflects on his farm upbringing and how it shaped his passion for plants. And Dr. Jared Barnes, an associate professor at Stephen F. Austin State University, talks about his journey into horticultural education and the creation of a unique campus botanical garden called The Plantery.

Whether you're a seasoned gardener or just getting started, these expert insights are sure to inspire your next project. Tune in to hear some of our favorite moments.

As we recorded this episode, snow was gently falling outside our windows here in New England. But that isn't depressing for us—it simply means it's time to start our seeds! Today we are joined by digital editor Christine, and we are talking all about which seeds we're starting this year and why. There's an assortment of edibles and flowers on our lists, and we discuss the best practices for getting them to germinate. Do all seeds need a heat mat? Or is it a good idea to pop your packets of seeds in the freezer before sowing them into a soil block? Get the answers to these pressing questions (and find out which zinnia had Danielle and Carol screaming with delight) in this pre-spring conversation.

Potted plants will bring life and positive energy into any room, and studies have shown that having them nearby can relieve stress, boost creativity, and improve focus. In winter, when the weather is not good for outdoor gardening, it is particularly satisfying when we can help the living gems on our windowsills to thrive and look their best. In this episode Danielle and Carol chat with their friend and colleague, Christine Alexander, about the houseplants they consider to be truly worthy of a spot indoors.

Catalogue descriptions for new plants may grab our attention, but usually provide little useful information about how these up-and-coming cultivars will perform in your garden. Fortunately, comparative trials like those conducted at Chicago Botanic Garden and Mt. Cuba Center put plants to the test, side-by-side, under typical garden conditions. In this episode, Richard Hawke and Sam Hoadley delve into a few of the similarities and differences between their trial programs. They compare notes, trade stories, and dispel a few misconceptions as they prepare for the talk they will give on Thurday, March 6th, 2025 as part of the Know to Grow lecture series at the Philadelphia Flower Show.

This week we might rename the show Pollinator Haven, the podcast where we dig into the vibrant world of pollinators and the plants that sustain them! Well, probably not, but we will be diving into the essential role host plants play in supporting bees, butterflies, hummingbirds, and other pollinators. These are species that are critical in providing places for insects to lay their eggs and food for hungry larvae. Whether you're a seasoned gardener or just starting out, you'll discover how choosing the right plants can turn your yard, balcony, or community space into a thriving ecosystem.

Susan Morrison, owner and principal designer at Creative Exteriors Landscape Design, has created hundreds of gardens in California's East Bay area. Her designs incorporate comfortable outdoor rooms into landscapes of all sizes, from hillside estates to postage-stamp front yards.

Susan's home garden features thoughtfully arranged spaces for relaxing and entertaining enfolded in an artful, water-wise plant palette. Focal point plants in key locations draw the eye through the landscape, inviting visitors to explore. In this episode, Susan describes her thought process for siting focal point plants, and shares some of the eye-catching cultivars she uses most often.

One deer can do major landscape damage overnight, and if a herd regularly visits your garden you may feel like giving up. Although almost no plant is completely safe if the herbivores are hungry enough, gardeners facing extreme deer pressure aren't powerless. Incorporating plants with "nasty" characteristics like strong smells, prickly textures, or even toxicity is one easy way to encourage those hooved hordes to browse elsewhere. In this episode, Danielle and Carol share some of the plants that have remained unscathed in their backyards, and expert Bonni Engelhardt weighs in with some of her own go-to selections.

Ulrich Lorimer is the director of the Native Plant Tust in Framingham, MA, a conservation organization that manages Garden in the Woods. He has been a longtime advocate for cultivating native plants in both public and private gardens to help offset habitat loss. In this episode, he talks about some outstanding native species that have an outsized impact when planted in a garden setting. He also digs into the nitty-gritty of designing with regionally adapted plants, gardening in a changing climate, and integrating native plants into our backyard ecosystems.

When we say "foundation plants" you might think we're talking about plants that are the backbones of our beds and borders. But that's not what we mean in this instance. Today we're discussing plants that are perfect for planting around your home's foundation. These selections need to adhere to a certain set of requirements: they can't get too big; they can't be too small; they can't have aggressive root systems; they must have multiple seasons of interest. If that sounds like the holy grail of plants, it is! But luck for you we've culled together a dynamic assortment of options for all areas of the country. So, if you're sick of looking at that ugly 2-foot expanse of concrete at the foot of your home listen up, because we're going to help you cover it up in style.
