About this listen

Horticultural science is the only discipline that incorporates both the science and aesthetics of plants. It is the science and art of producing edible fruits, vegetables, flowers, herbs, and ornamental plants, improving and commercializing them. Plants, People, Science, a podcast by the American Society for Horticultural Science (ASHS), will bring you the recent advancements in science, technology, innovation, development, and education for economically important horticultural crops and plants. Each episode features an interview with an American Society for Horticultural Science member, a discussion of their current work in the field, and the story behind their research. ASHS members focus on practices and problems in horticulture: breeding, propagation, production and management, harvesting, handling and storage, processing, marketing and use of horticultural plants and products. In this podcast, you will hear from diverse members across the horticultural community - scientists, educators, students, landscape and turf managers, government, extension agents, and industry professionals.

  • What It Takes To Make A Super Cold-Hardy Wine Grape
    Jan 5 2026

    Think a great wine grape can’t survive where winters drop to minus forty? We sit down with breeder Dr. Harlene Hatterman-Valenti from North Dakota State University to unpack how a young industry, a focused research program, and some stubborn optimism produced two new cultivars built for the northern plains. From the early days of variety trials and policy hurdles to the release of Dakota Primus and Radiant, Harlene shares how hybrid genetics, gritty selection, and clever management turned a hostile climate into an advantage.

    We dig into the science of cold hardiness: why photoperiod sensitivity matters more than you think, how vines must read shortening days to lay down periderm before sudden freezes, and the three critical windows where cold injury strikes—fall acclimation, deep midwinter lows, and late-winter temperature whiplash. Harlene explains the growth calendar for a North Dakota vineyard with just 130 frost-free days, from delayed pruning and cautious budbreak to early-August veraison and mid-September harvests.

    Beyond the vineyard, we explore how the state’s wine scene found its footing, why regulations evolved to support consistent supply, and how tourism now fuels growth. The conversation closes with what’s next: chasing an ultra-cold-hardy red, expanding into table grapes for farmers markets, and celebrating the team effort—students, specialists, and collaborators—that made progress possible. If you’re curious about cold-climate viticulture, breeding under polar vortex pressure, or how science builds regional wine identities, this one’s for you.

  • The ASHS Annual Conference: Gathering the Horticultural Science Community for Learning and Collaboration
    Oct 28 2025

    We sit down with our podcast teammate Lena Wilson—fresh off a first-place PhD Graduate Student Poster Competition win—to unpack what it takes to thrive at a major scientific conference, from crafting a clear two-minute story to turning a poster row into a collaboration engine.

    Lena takes us inside a week in New Orleans at her first ASHS Annual Conference. We trade practical tactics for session planning, using the conference app without becoming a prisoner to it, and scheduling specific meetups before everyone’s calendar fills up. You’ll also hear quick voice clips from students, postdocs, faculty, and industry partners sharing what they do while listening to podcasts—tissue grinding, figure polishing, micropropagation - plus why they keep returning to ASHS: community, mentorship, and science that feeds people.

    We also look ahead to ASHS 2026 in Dallas, August 3-7, 2026. If you’re a graduate student aiming for your first big presentation, an early-career scientist ready to widen your circle, or a faculty member scouting new collaborations, you’ll leave with a clearer plan and renewed energy.

    Subscribe for more conversations with researchers, educators, and industry leaders across horticultural science. Share this episode with a colleague who needs a nudge to submit that abstract, and leave a review to help others discover the show.

  • The Art of Teaching: Dr. Chad Miller's Innovative Classroom Trade Shows
    Sep 12 2025

    Dr. Chad Miller from Colorado State University shares his innovative approach to teaching horticulture through a classroom trade show format that transforms traditional plant identification courses into engaging, multidimensional learning experiences. As the 2024 ASHS Outstanding Undergraduate Educator award winner, he discusses how he combines plant knowledge with professional skill development to prepare students for success beyond the classroom.

    • Creating a trade show environment where students showcase plant knowledge creatively
    • Moving beyond memorization to develop professional communication skills
    • Using peer evaluation to help students learn to give and receive constructive feedback
    • Approaching teaching as scholarship worthy of research and publication
    • Balancing high expectations with understanding of students' complex lives
    • Finding joy in seeing students succeed professionally
    • Establishing a classroom culture where it's safe to not know and to learn from mistakes

    To read more about Dr. Miller's teaching approach, check out his award-winning paper "Classroom Trade Show: An Alternative to Traditional Classroom Presentations in an Undergraduate Plant Identification Course" in HortTechnology. If you're interested in teaching innovations in horticulture, consider joining the ASHS Teaching Methods Interest Group.
