Podcast episode by Nicole Johnsey Burke (Grow Yourself) about sweet potatoes: their high nutrition (notably vitamin A, fiber, antioxidants including anthocyanins), cultural history (origin in Central/South America with possible Polynesian contact ~1000 AD), major U.S. production states (North Carolina, Louisiana, California, Mississippi, Texas), botanical classification (Convolvulaceae), and practical growing guidance (grow from slips after frost, spacing, curing and storage 6–10 months). The host mixes science, gardening tips, anecdotes and a cookbook recommendation.
