Plants, People, ScienceAuthor: American Society for Horticultural Science (ASHS)
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
Episode 7
Monday, 5 January, 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.Additional information in available in these articles:Complex Plant Process Trait Evaluation Through Decomposition of Higher-order Interaction: A Case Study in Acclimation Responses of Cold-climate Hybrid Grapevine Through Bilinear and Multiway MethodsCold Climate Winegrape Cultivar Sensitivity to Sulfur in the Northern Great Plains Region of the United States‘NDMutant1’: A Novel Determinate Interspecific Grapevine for Genetic and Physiological Study and Breeding ApplicationsEnjoyed the conversation?
