Ep. 39 - What You Need to Know About the New Glow-in-the-Dark Firefly Petunia

The Firefly bioluminescent petunia has captured attention both inside and outside the floriculture industry for its ability to bring natural illumination into homes and gardens. But where did it come from, how is it changing the game in plant genetics research, and perhaps most importantly, when and how will growers and consumers be able to find it? In this episode, I talk to the team at Rooted in Solutions, the exclusive licensed distributor of the plant in North America through a partnership with Light Bio. Rooted in Solutions is led by industry veterans Susie Raker and Casey Stanton of Raker-Roberta’s Young Plants in Michigan, along with Jim Devereux of Green Fuse Botanicals in California. 

Ep. 38 - Steve Costa of Headstart Nursery on the Importance of Giving Back

Steve Costa, the president of Headstart Nursery in Gilroy, CA, is a proud graduate of Cal Poly San Luis Obispo. So proud, in fact, that he recently provided a sizable donation to support the restoration of the school’s Horticulture Greenhouse Complex and further its learn-by-doing approach to agricultural education. In this episode, I talk to Steve about the importance of fostering the next generation of growers, as well as how Headstart Nursery has become a leader in transplant production. Here’s our conversation.

Ep. 37 - A Frank Conversation on the Challenges Facing the Future of Horticulture Research

Growers in the floriculture industry face many challenges when it comes to retaining key talent and building the next generation of industry leaders. The same holds true for both university Extension and the supplier community, two critical segments of the greenhouse market. In this episode of Greenhouse Grower to Grower, I talk to Melinda Knuth of North Carolina State University, and Brian Schulker of Jiffy Group, about a range of topics, including how researchers, manufacturers, and growers can all work together to navigate the barriers each of these market sectors are faced with, and what might happen if we don’t face these challenges head on. Here’s our conversation. 

Ep. 36 - Up Close With John Mark Courtney of Kind Earth Growers

The cover story of Greenhouse Grower’s November issue provides a closer look at Kind Earth Growers, a wholesale plant nursery in Ottsville, Pennsylvania, that offers more than 215 species of seed-grown native perennials and aquatic plants under 20,000 square feet of controlled-environment production. In this episode of Greenhouse Grower to Grower, you can hear my full conversation with Kind Earth owner John Mark Courtney and learn more about how his passion for native plants led to the launch of a new business that has become well known for its focus on quality and education about native plants. 

Ep. 35 - The Garden Trends You Need to Know About With Katie Dubow

The Garden Media Group released its official 2025 trends report in early September. In this episode, I sat down with Katie Dubow, president of Garden Media Group, to get a first-hand look at what’s in this year’s report, and how you as a grower, or if you’re in another segment of the industry, can respond. Here’s our conversation.

Ep. 34 - Get to Know Lauren Kirchner of Spring Creek Growers

Lauren Kirchner left Waller, Texas when she was 18 to pursue a career in marketing and finance. She never thought she’d return to join her parents in running Spring Creek Growers, but that’s exactly what happened. Over the last couple of years, Lauren worked with her parents on an ownership transition at Spring Creek, and that was quickly followed by perhaps an even bigger challenge: a deadly tornado that came through the area earlier this year. Not only did Spring Creek come out of that stronger, it helped Lauren become a better leader. I recently caught up with Lauren to talk about what she’s learned along the way, how she works side by side with her team, and how she’s helping to develop the next generation of gardeners, Here’s our conversation.
