"Fruit trees need hands-on care." That's the motto of our guest, Susan Poizner of OrchardPeople.com. Susan is an urban orchardist, teacher, journalist, and filmmaker. She is the author of Growing Urban Orchards (2014), cofounder of the Ben Nobelman Park Community Orchard in Toronto and the host of the Urban Forestry Radio podcast. She also teaches fruit tree classes on her website. Colleen was eager to interview Susan after taking her online courses. Susan gives us the basics on why fruit trees need human intervention to thrive; we also discuss urban orchards, heirloom species, food forests, and Susan's transition from journalism to horticulture. Then Colleen and Leah discuss the impact of Austin's recent ice storm on fruit trees. Mentioned in this episode: North American Scion Exchange (Facebook group).

A rose by any other name would smell as sweet, but some of the common names we use for plants downright stink! In this episode, we're diving into problematic colloquial names. Some common names are geographically misleading ("Jerusalem artichoke"); others are xenophobic, racist, or antisemitic ("wandering Jew"); while still others are an unfortunate combination of both ("Turk's cap"). While it's probably too much to expect everyone to start using Latin names for plants, we can adapt new common names that are more culturally sensitive and accurate. Like the plants themselves, common names are organic, living things that need to evolve over time. First up, some armadillo drama and an update on Colleen's super-low-maintenance front yard renovation inspired by the writing of Roy Diblik (here's our original episode about that.) Mentioned: Great at Procreate, an online digital drawing course from instructor Amy Fedele; "Problematic Common Names" (House Plant Hobbyist, 2021); How Plants Get Their Names by L.H. Bailey (Macmillian, 1933); Native Flora of Texas by the Texas Highway Department (undated, ca. 1960); The Better Common Names Project of the Entomological Society of America; and Potentially Problematic Common Names, a study by the American Public Gardens Association (2021).

In this episode, Colleen unearths as much as she can about the largely unwritten history of plant pots. When did humans start growing plants in containers? How did innovations in materials and technology lead to the domestication of plants, plant collecting, and the growth of the nursery industry? Why are plant pots so overlooked as a facet of industrial design? (We can rattle off several iconic chair designs, but flowerpots? Not so much.) Why don't the standardized names of nursery pot sizes correspond to their actual volume in the US? We have more questions than answers, folks. First up, Leah is practicing her drawings. And we need an alternative name for the tricky season that comes between summer and fall in Texas. Join our Patreon for bonus episodes and more!

On this episode, we dive into ecologist Douglas Tallamy's books Nature's Best Hope (2019) and The Living Landscape (2014, with Rick Darke). Tallamy's work takes native plant gardening and wildlife gardening to another level by focusing not just on species diversity, but on diversity of species interaction to promote ecological conservation. According to Tallamy, "native" plants are those which have "evolved in a given place over a period of time sufficient to develop complex and essential relationships with a diversity of animals." Native plants, then, are organisms that have interacted with insects, birds, and mammals for thousands, if not millions, of years. We discuss Tallamy's perspective and the how we might tackle the challenge of implementing a conservation design -- and convincing homeowners to think of themselves as land stewards. Up first: It's hot here in Austin, so we are talking about what early triple-digit temps mean for gardeners. Leah is looking for her niche, taking inspiration from specialist insects.

Also - after recording, we found this article from the NWF about yucca moths. (Their caterpillars eat the yucca seeds and flowers, not the leaves! Then the moths pollinate the yuccas in return!)

Happy New Year! We're back from vacation with a discussion of a book that is very much in the Horticulturati wheelhouse, The Know Maintenance Perennial Garden. Author Roy Diblik, a Wisconsin-based designer and plantsman, argues that anyone can build a "design-magazine-worthy garden at home" by thoughtfully combining perennials to form functional plant communities that need little more than an annual mow – almost no irrigation, mulch, or hand-pruning required. This low-maintenance method could be a revelation for residential and commercial landscapes alike, but can it work in Texas, with our balmy winters and scorching summers? Is there a way to implement the mowing-for-maintenance concept using electric, rather than gas, machines? Colleen is inspired to experiment as she redesigns her front yard. Next, we review a documentary short, The Soul of a Farmer, by filmmaker Roger Sherman. Chef-turned-grower Patty Gentry of Early Girl Farm rents three acres in Long Island from Isabella Rosselini (!!!), who calls Patty "the Picasso of Vegetables." Sidestepping many of the tropes of farm-to-table docs (Gentry admits she'd probably be living out of her truck if it weren't for her spouse's financial support) this film paints an honest portrait of the struggles and small victories of one artisanal vegetable grower as she transitions from wholesale growing for restaurants to a Community Supported Agriculture (CSA) model.

A year ago, we recorded a long and rambly episode on garden design. Now we're making it an October tradition! Revisiting the subject, we realize our approaches to design have changed, but we're still hell-bent on questioning basic tenets. How important is color? Are foundation shrubs necessary? Should we flip the script on "seasonal interest?" Does "timesharing with plants" really work? Join us at the picnic table as we parse out some jargon (form, texture, verticality), swap tips, and get hangry for cookies. Mentioned in this episode: Five Seasons: The Gardens of Piet Oudolf (2017) and Planting in a Post-Wild World by Thomas Rainer and Claudia West (2015).

Fresh off a hometown visit to Cleveland, Colleen brings us the story of the Cuyahoga: a river once so polluted with industrial sludge, it burned. At least thirteen times. While the largest and most damaging conflagration occurred in 1952, it was the 1969 river fire that made national headlines, thanks to Mayor Carl Stokes. As one of the first Black mayors of a major American city, the charismatic and media-savvy Stokes connected the dots between economic inequality and environmental degradation, and advocated on the national stage for legislation that would clean up the "urban environment," starting with the Cuyahoga and Lake Erie. Today, the pristine Cuyahoga is a symbol of pride for Clevelanders, yet this civic success story belies the reality of ongoing inequality there. Colleen shares her personal history of growing up in "a city with no superlatives," her own chance connection to Stokes, and how she's begun parsing the difference between "environmentalism" and "environmental justice." Also, Leah shares an update on the so-called Mystery Seeds from China. Visit our website for more info. Support The Horticulturati on Patreon for bonus content and early access to episodes.

Enter the hive with us for another classic critter topic: BEES! We recorded so much on bees that we have to split this bee-nanza into a two-parter! In part one, Leah suits up for a tour at Two Hives Honey in Manor, Texas, and investigates honeybee ecology. In part two, we'll focus on how, as a gardener, you can support our honey-making friends (along with native bees and other pollinators). What are honeybees? Why do they live in boxes? And how did Apis mellifera, just one of tens of thousands of bee species in the world, become so ubiquitous in our gardens? We'll answer these questions and more with the help of professional beekeeper Samantha Dula. Mentioned in this episode: The Beekeeper's Bible by Richard A. Jones and Sharon Sweeney-Lynch; and Bee City (1951), a short film about honeybees narrated by sportswriter and amateur naturalist John Kieran.

Autumn has come to Texas at long last! To celebrate, we watched the documentary Five Seasons: The Gardens of Piet Oudolf (2017) by Thomas Piper, and we're now officially card-carrying Piet stans sporting Dutch accents, asymmetrical haircuts, and scythes. We discuss Oudolf's "mathematics" of design, seasonal ambience, and the art of garden editing. How might we translate Oudolf's temperate palate to the not-so-temperate climate of central Texas?

Turtle rabbit. Shell possum. Roadkill. Whatever you call it, the nine-banded armadillo is a mysterious, ancient, and unfairly maligned mammal. Find out everything you ever wanted to know (and more) about this Texas icon. Leah traces the armadillo's bizarre migratory history, its role in medical research, and its rise as a symbol of the Austin music scene. We'll bust some armadillo myths, meet some famous champions (including naturalist Roy Bedichek and artist Jim Franklin) and discuss the intractable problem of armadillos in the garden. So, spark up a spliff and fill your pantyhose with worms! The next time one wreaks havoc on your flowerbeds, you may just have a little more appreciation for this humble critter.
