Plants, People, Science

Many horticulture students feel like they have to choose early: academia or industry, teaching or “real world” work, research or marketing. We wanted to test that assumption, so we sat down with Dr. Alicain Carlson from Syngenta Flowers, a cut flower scientist who built a career that blends floriculture research, technical problem-solving, leadership, and science-backed marketing. Alicain is currently serving as the ASHS Industry Division Vice President and was named ASHS Outstanding Industry Scientist in 2025.

Alicain walks us through her path from Virginia Tech to graduate work at NC State studying cut flower production and postharvest quality, and then the moment she took an unexpected leap into the commercial side of horticulture. We talk about what Syngenta Flowers actually does as a global flower breeding company, and why the best marketing in plant science is not fluff. It is trial data, clear comparisons, and practical guidance that helps growers choose varieties, manage growth regulators, and hit production targets.

We also get specific about career development: how student organizations, teaching assistant roles, and conference presentations build the leadership, communication, and project management skills that employers pay for. Then we dig into networking that feels human, including simple follow-ups, local grower meetings, and using LinkedIn without turning it into a performance. Finally, Alicain breaks down the California Spring Trials as a can’t-miss floriculture event for seeing new genetics, meeting breeders, and spotting collaboration opportunities with universities.

Most of us think new crop horticulture cultivars are invented behind closed doors, then handed to farmers as a finished product. We wanted to explore that assumption, so we sat down with Dr. Ambar Carvallo Lopez, currently a Post Doctoral Research Associate at the University of British Columbia and an ASHS award-winning author and plant breeder whose work shows how research progresses when growers and consumers Participate in the science. If you care about better-tasting tomatoes, resilient organic agriculture, and the future of local food systems, this conversation connects the dots from seed to plate. 

In this episode we walk through the concept of participatory plant breeding, where farmers are involved early to define breeding objectives and then help shape selection by trialing lines on their farms. This is a unique form of citizen-science.  
Ambar shares how the University of Wisconsin-Madison, Where she completed her PhD, tomato breeding program uses iterative seed exchange and real-world feedback to shorten the “will this work on my farm?” gap that often slows adoption. Along the way, we talk about genotype by environment interactions, high tunnel production, and why building trust with stakeholders can be as important as collecting data. 

Ambar explains why tomato flavor may have declined over time as breeding programs prioritized yield, disease resistance, and plant structure, and how accessing heirloom tomato diversity can help recover the genes and volatile compounds tied to better aroma and taste. In the conversation also digs into practical breeding targets for organic systems, including foliar diseases like Septoria leaf spot and early blight, plus the behind-the-scenes reality of deciding when a line is ready to release and how to handle credit and IP when farmers are true co-creators. 

If you finish this episode thinking differently about what’s behind a great tomato, share it with a friend, subscribe for more horticultural science, and leave a review so more listeners can find the show.

A sunrise ride to an apple orchard changed everything for Dr. Gina Fernandez—and it might change how you think about berries. We sit down with the NC State distinguished professor and berry breeder to trace the path from cold-hardy apple rootstocks in Minnesota, to thornless blackberries in Arkansas, to a career defining strawberries, raspberries, and blackberries across the Southeast. Along the way, Gina reveals what makes a cultivar truly stand out: not just yields or firmness, but flavor that keeps people coming back.

Gina explains how she first joined NC State to tackle cultural management and methyl bromide alternatives, then stepped into breeding as the program shifted. We dig into the trials that helped launch a North Carolina blackberry industry, why thornlessness and resistance to double blossom were pivotal, and how later threats like orange rust and fusarium reshaped goals. On strawberries, she unpacks the split between shipping acreage and local pick-your-own farms, and more. We also talk about berry varieties Gina and her team have released over the years, specifically the blackberry 'Von' and the raspberry 'Nantahala', as well as the upcoming release of her new blackberry, NC740, to be called 'Ervin'.

Beyond genetics, Gina shares how science moved from solo wins to team science, and how she mentors through “Team Rubus” with weekly cadence, trust, and room for students to grow. Expect practical wisdom for early‑career researchers: travel to see different systems, build writing muscle, and collaborate across pathology, entomology, breeding, and economics to solve real grower problems. If you care about berry breeding, flavor, disease resistance, and how ideas become fruit on the table, this conversation delivers a full plate.

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.

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.
