{"type":"firestarter.listing","listing":{"id":"lst_QlKC8Zy0","product_name":"Tuxana Sweet Corn","category":"Vegetables","description":"Another excellent variety from Jonathan Spero of Lupine Knoll Farm. This bright white sweet corn is much sweeter than most OP corns and is great for fresh eating, or for using salsas, soups, and chowders. Its subtle creaminess gives it a flavor more complex than simple sweetness. Plants will produce 2 ears each.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Tuxana-Sweet-Corn-vendor-unknown-1630681134.jpg?v=1735579477","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Tuxana-Sweet-Corn-vendor-unknown-1630681137.jpg?v=1735579477"],"price":5.39,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:38.427Z"},"share_url":"https://firestarter.network/l/lst_QlKC8Zy0","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
