Ep. 279 - A Pollinator Plant of the Year Program

August 23, 2020

There is a lot of information out there on which plants to choose for your garden. Often this information is geared towards a wide audience living in vastly different climate zones. As such, it can be extremely difficult to figure out what will work best for you. That is why I am excited to sit down for a conversation with Lauren Muller, the Conservation Outreach Coordinator for the State Botanical Garden of Georgia, to talk about their innovative Pollinator Plants of the Year Program. This program is centered on making regionally specific recommendations for gardeners to help improve the ecological function of their gardens. This program goes far beyond recommendations as well. Lauren and her team are working on all aspects of the gardening process, from sourcing seeds and propagating plants to working with local nurseries and communities to not only pick plants that benefit all kinds of pollinators but to make sure they are available to the public. This program is such a great example of thinking globally but acting locally.

Ep. 268 - How Small Flies Made A Lot Of Orchids

June 7, 2020

In this episode, we are joined by PhD student Melissa Díaz-Morales and Director of the Lankester Botanical Gardens, Dr. Adam Karremans to look at how flies have managed to influence the evolution of the largest subtribe of orchids in the world - the pleurothallids. This remarkable group of orchids is home to over 5,000 unique species and presents some of the most stunning and complex floral morphology of the entire orchid family. They also undergo some serious chemical ecology that helps attract their fly pollinators. We also explore the difficulties in both studying and publishing pollination work and how that can hinder our understanding and conservation of these plants. This episode is sponsored by The Great Courses Plus and was produced in part by Mr. Keith Santner, Dana, Chloe, Aaron, Sara, Kenned, Vaibhav, Kendall, Christina, Brett, Jocelyn, Kathleen, Ethan, Kaylee, Runaway Goldfish, Ryan, Donica, Chris, Shamora, Alana, Laura, Alice, Sarah, Rachel, Joanna, Griff, Philip, Paul, Matthew, Clark, Bobby, Kate, Steven, Brittney, McMansion Hell, Joey, Catherine, Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Liba, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Benjamin, Eli, Rachael, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 213 - Buzzing Bees and the Floral Microbiome

May 19, 2019

We tend to view pollination as an altruistic blending of plant and animal behavior but altruistic it is not. Both plants and their pollinators are trying to get as much as they can out of the relationship while giving as little in return as possible. What really blows my mind is just how much we still have yet to learn about this vital ecological process. That is where scientists like Dr. Avery Russell come in. Dr. Russell specializes in pollinator behavior in the context of the various drivers that push bees towards specialist lifestyles. Along the way we will learn about how the floral microbiome may be influencing the evolution of these relationships. If you truly care about plants and their pollinators, this is one episode you do not want to miss!

Ep. 179 - Demystifying Orchids

September 23, 2018

Orchids are some of the most popular plants in all of the world. This hyper-diverse plant family captures our imagination like no other. So often, the true lives of orchids are so strange, so bizarre, that it can seem that anything is possible with these plants. This is one of the main reasons why orchids are also subject to a lot of speculation. My guest today is here to talk about why orchids are so mysterious and to set the record straight on a handful of orchid stories. Joining us from the Lankester Botanical Garden in Costa Rica is orchid specialist Dr. Adam Karremans. Dr. Karremans studies orchid diversity and ecology and he has set out to write a book all about the mysterious world of orchids. The better we get to know these plants, the better we can work to conserve them and the habitats they need for survival. This episode was produced in part by Stephen, Botanical Tours, Moonwort Studios, Lisa, Liba, Lucas, Mohsin Kazmi Takes Pictures, doeg, Daniel, Clifton, Stephanie, Rachelle, Benjamin, Eli, Rachael, Anthony, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Brian, Mark, Rens, Bendix, Irene, Holly, Mountain Misery Farms, Caitlin, Manuel, Jennifer, Sara, and Margie.

Ep. 173 - What the Dogbane Family Can Teach Us About Pollination

August 12, 2018

Pollination is a fascinating phenomenon to ponder. There seems to be as many variations on the subject as there are flowering plant species. Wonder and amazement wait around every corner. My guest today has devoted his career to such investigations. Joining us is University of Northampton professor Dr. Jeff Ollerton who, among other things, studies members of the family Apocynaceae as a model system for the complexities of plant/pollinator interactions. This family of plants contains many familiar species and many you may have never heard of before. Join us for a fascinating discussion about this charismatic group of plants.

Ep. 167 - Trial Gardens at Mt. Cuba Center

July 1, 2018

Nativars are frequently seen as unnatural mutant versions of their wild counterparts whose use overlooks the whole point of natives in the first place. Take, for instance, the popularity of double flowered nativars. These plants have been selected for an over-production of sepals and petals that can be so dense that they preclude visitation by pollinators. It would seem that nativars are a slippery slope to yet another sterile landscape incapable of supporting biodiversity. However, anecdotes don’t equal data and that is where places like Mt. Cuba Center come in. Located in northern Delaware, Mt. Cuba is doing something quite amazing for the sake of environmentally friendly landscaping – they are putting plants to the test. Joining us today is Manager of Horticultural Research, George Coomb to talk about what Mt. Cuba Center's trial gardens are all about.

Ep. 78 - A Focus On Native Bees

October 16, 2016

North America is home to a plethora of native bees. Sadly, they are a bit of a mystery. Overshadowed by non-native honey bees, many of our native species are in serious trouble. That is where scientists like Dr. Alexandra Harmon-Threatt come in. An assistant professor of entomology at the University of Illinois, her lab is focused on the interactions between native bees and the surrounding plant communities. This is a fascinating discussion that will hopefully inspire more people to dive into the shadows surrounding these important players in our local ecology.
