All the Plant Shows, part two

Plant podcasts are big these days, or at least that’s what it seems, which is why this has turned into a multi-part post (see part one). While in the process of compiling a list of plant podcasts that I’ve become aware of, I keep stumbling onto more. Which is great! It’s a trend that I hope continues. As it continues, I will go on compiling them here until we have ourselves a list of All the Plant Shows!

Planthropology – Plants plus anthropology equals Planthropology. This podcast covers all the many ways that plant lives and human lives intersect and features conversations with plant people about their love of plants and the work they do that involves plants. Vikram (the host) is a chatty and genial guy and a great twitter follow.

The Plant Prof – Another Vikram joint. This spin-off of Planthropology features Vikram sans guests talking about an assortment of plant-related topics. Each episode is only a few minutes long. Quick, casual, and easy to digest.

Plant Daddy Podcast – Houseplants are quite popular these days, likely due to the growing number of people living in dense urban areas. Apartment living generally means that if you want to garden, you have to do it indoors and/or on a balcony. With increased interest in indoor growing comes a slew of podcasts about it. Plant Daddy Podcast is one of the best. Matthew and Stephen really know their plants and have years of combined experience caring for a vast number of species. Other plant experts occasionally join the show to talk about the specifics of cultivating and caring for plants in small spaces.

Plantrama – Mainly a gardening podcast, but very plant-focused. C.L. and Ellen are experienced gardeners and quite knowledgeable about plants. Episodes come out regularly, and each one is under 30 minutes. In that time, the hosts cover at least three topics. Juniper berries, begonias, and orchid pots, for example. Or cherry tomatoes, silverberry, and saving seed. It’s two good friends having a chat about plants, and you get to listen in.

The Plant Kiki – A kiki is a casual conversation among friends. When plants are a major theme of the discussion, it’s a plant kiki! For each episode, Colah, of Black in the Garden podcast (another must listen), brings together a group of friends to talk about plants and whatever else comes up. The conversations are lively, humorous, insightful, and fun. If you enjoy exploring questions like “If Beyoncé were a plant, what plant would she be?” this podcast is for you.  

Crime Pays But Botany Doesn’t – Joe is a self-described misanthrope. He doesn’t care much for people, but he loves plants (and geology). This podcast is similar to Joe’s You Tube channel of the same name, in that it’s mostly him describing his time botanizing in various locations across North America and beyond. Expletive-filled rants help fill the time. Occasionally Joe brings on a guest to talk about plants (or trains). With hours and hours of content available, this is easily one of the best and most entertaining plant shows around.

The Taproot – A podcast produced by Plantae, a plant science hub created and managed by the American Society of Plant Biologists. Each episode is an interview with an individual who is working in or studying plant science. There are discussions about the work that went into a particular plant science journal article, as well as conversations about navigating academia and professional life. It’s a great source of information for students and professionals, with excellent tips on how to succeed in educational pursuits and beyond.   

PlantNetwork Podcast PlantNetwork is an organization that supports public gardens and professional gardeners in Britain and Ireland. Their podcast is a series of short interviews with people who work at public gardens or in some other capacity in the horticulture industry.

Speaking of public gardens, educating the public about plants is a mission of botanic gardens and arboreta. Some botanic gardens do this through podcasts. Below are a few that I have come across. If you happen to be aware of others, please let me know.

Branch Out – A plant science podcast produced by The Royal Botanic Garden Sydney with a catalog consisting of six seasons covering a wide array of plant-based topics. Vanessa geeks out about plants and nature with a bevy of incredible guests. No surprise, much of the content concerns Australian plants, gardens, agriculture, and ecology. But who isn’t fascinated by Australia’s flora and fauna? The production on each episode is excellent, and the stories are captivating. 

Plant Power – A short series of podcasts produced by North Carolina Botanical Garden highlighting just how essential plants are to life on earth. Brief conversations about climate change, protecting pollinators, growing and conserving native plants, etc. 

Botanical Mystery Tour – A delightful podcast from Chicago Botanic Garden that takes the stories of plants in popular culture and explores the science behind them. In each episode, a staff member at CBG joins the hosts, Jasmine and Erica, to discuss the topic and talk about their work at the Garden. Whenever botany shows up in popular culture, it’s an event worth celebrating. It’s good to know there’s a podcast devoted to this cause.

Unearthed: Mysteries from an Unseen World – A podcast series from Royal Botanic Gardens Kew hosted by James Wong. Each episode is a mini audio documentary investigating a particular mystery, story, or current event involving plants (or, in the case of one episode, fungi). This podcast has great production and excellent, fact-based storytelling – exactly the sort of thing you’d expect from a place like Kew.

These certainly aren’t all the plant shows. Part three is in the making. In the meantime, is there a particular plant-themed podcast (or podcast episode) that you enjoy and would like to recommend? If so, share it with us in the comment section below.

Podcast Review: Botanical Mystery Tour

My interest is piqued any time plants are featured or plugged in popular culture. Hence my ongoing series of posts, Botany in Popular Culture, featuring Futurama, Saga of the Swamp Thing, etc. Plants just don’t get enough airtime, so it must be celebrated when they do. Which is why I was excited to learn about Chicago Botanic Garden‘s new podcast, Botanical Mystery Tour, in which the plants referenced in pop culture take center stage.

The hosts, as they state in each episode’s introduction, “dive into the botany hidden in our favorite stories.” To help with the discussion, they bring in experts that work at Chicago Botanic Garden to explore the science (and fiction) behind the plant references. In addition to discussing pop culture and the related science, the guests share details about the work they do at the Garden and some of the research they are working on.

In the first episode, Jasmine and Erica ask Paul CaraDonna about the drone bees featured in an episode of Black Mirror. Since many bee species are in decline, will we have to resort to employing robot bees to pollinate plants that rely on bee-assisted pollination? A great discussion about native bees and colony collapse disorder ensues.

(But maybe the idea of autonomous drone insects isn’t too far-fetched…)

In episode two, the hosts ask why humans are so obsessed with corpse flowers. Thousands of people flock to botanical gardens to see these humongous, stinky flowers on the rare occasions they are in bloom, so what is so appealing about Amorphophallus titanum? Patti Vitt joins the discussion to share details about this fascinating plant.

A corpse flower in bloom is a brief and uncommon occurrence, reminiscent of the Sumatran Century Flower in The Simpsons and the 40 Year Orchid in Dennis the Menace.

 

The third episode features the sarlaccs of Star Wars. It turns out, sarlaccs are carnivorous plants. This discovery spawns an interesting discussion with horticulturist Tom Weaver about what defines a carnivorous plant and the various ways that different carnivorous plant species capture and kill their prey.

The fourth (and latest) episode is an exploration into the magical world of mushrooms. In Alice in Wonderland, Alice encounters a large, hookah-smoking caterpillar sitting atop a giant mushroom. Are there mushrooms big enough that a person could actually sit on them like Alice does? Greg Mueller joins the podcast to address this and many other mycology-based questions. The conversation includes a great discussion about why a botanical garden (whose main focus is plants) would be interested in fungus.

The discussions in this podcast are fun and enlightening. The hosts shine the spotlight on often overlooked characters in popular media, and with the help of their guests, lead captivating conversations about the science related to these characters. With only a handful of episodes available so far, it will be easy to get caught up. And then you, like me, will find yourself anxiously looking forward to embarking on another Botanical Mystery Tour.

Screening for Invasive Plants at Botanical Gardens and Arboreta

As discussed in last week’s post, many of the invasive species that we find in our natural areas were first introduced to North America via the horticulture trade. As awareness of this phenomenon grows, steps are being taken by the horticulture industry to address this issue. The concluding remarks by Sarah Reichard and Peter White in their 2001 article in BioScience describe some recommended actions. One of them involves the leadership role that botanical gardens can play by both stopping the introduction and spread of invasive species and by presenting or promoting public education programs.

Reichard and White offer North Carolina Botanical Garden as an example, citing their “Chapel Hill Challenge,” which urges botanical gardens to “do no harm to plant diversity and natural areas.” Reichard and White also encourage botanical gardens and nurseries to adopt a code of conservation ethics addressing invasive species and other conservation issues. Codes of conduct for invasive species have since been developed for the botanical garden community and are endorsed by the American Public Gardens Association.

 

Botanical gardens that adopt this code have a number of responsibilities, one of which is to “establish an invasive plant assessment procedure,” preferably one that predicts the risks of plant species that are new to the gardens. In other words, botanical gardens are encouraged to screen the plants that are currently in their collections, as well as plants that are being added, to determine whether these plants currently exhibit invasive behavior or have the potential to become invasive. Many botanical gardens now have such programs in place, and while they may not be able to predict all invasions, they are a step in the right direction.

In an article published in Weed Technology (2004), staff members at Chicago Botanic Garden (CBG) describe the process they went through to determine a screening process that would work for them. CBG has an active plant exploration program, collecting plants in Asia, Europe, and other parts of North America. Apart from adding plants to their collection, one of the goals of this program is to find plants with horticulture potential and, through their Ornamental Plant Development department, prepare these plants to be introduced to the nursery industry in the Chicago region. As their concern about invasive species has grown, CBG (guided by a robust Invasive Plant Policy) has expanded and strengthened its screening process.

In order to do this, CBG first evaluated three common weed risk assessment models. The models were modified slightly in order to adapt them to the Chicago region. Forty exotic species (20 known invasives and 20 known non-invasives) were selected for testing. Each invasive was matched with a noninvasive from the same genus, family, or growth form in order to “minimize ‘noise’ associated with phylogenetic differences.” The selected species also included an even distribution of forbs, vines, shrubs, and trees.

Weed risk assessment models are used to quickly determine the potential of a plant species to become invasive by asking a series of questions about the plant’s attributes and life history traits, as well as its native climate and geography. A plant species can be accepted, rejected, or require further evaluation depending on how the questions are answered. For example, if a plant is known to be invasive elsewhere and/or if it displays traits commonly found in other invasive species, it receives a high score and is either rejected or evaluated further. Such models offer a quick and affordable way to weed out incoming invasives; however, they are not likely to spot every potential invasive species, and they may also lead to the rejection of species that ultimately would not have become invasive.

After testing the three models, CBG settled on the IOWA-modified Reichard and Hamilton model “because it was extensively tested in a climatic zone reasonably analogous to … Illinois,” and because it is easy to use and limits the possibility of a plant being falsely accepted or rejected. The selected model was then tested on 208 plants that were collected in the Republic of Georgia. Because few details were known about some of the plants, many of the questions posed by the model could not be answered. This lead CBG to modify their model to allow for such plants to be grown out in quarantined garden plots. This way pertinent information can be gathered, such as “duration to maturity; self-compatibility; fruit type and potential methods of seed or fruit dispersal; seed production, viability, and longevity in the field; and vegetative spread.” CBG believes that evaluations such as this will help them modify their model over time and give them more confidence in their screening efforts.
