{"type":"firestarter.listing","listing":{"id":"lst_7eSGtHT2","product_name":"Martian Jewels Sweet Corn Seeds","category":"Seeds & Plants","description":"Though the striking color is other-worldly, the flavor of this one-of-a-kind jewel is more traditional—slightly less sweet than modern, very sweet hybrids. It was a labor of love to produce an open-pollinated corn that is loaded with beneficial anthocyanins (antioxidants), thanks to its Native American Hopi blue corn parents. Harvest fresh, or wait a bit longer and the sugar subsides, becoming perfect for breads or chowder, or wait even longer to harvest, and use the dried kernels for flour.","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3180i_Corn-Sweet-Martian-Jewels-ORG_1a85d192-0ee6-44ee-87ac-349a86ea07e2.jpg?v=1773114787","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3180si_Corn-Sweet-Martian-Jewels-ORG_56386c2a-efe1-4abc-9fdc-5e4426ef2780.jpg?v=1773114787","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3180w_Corn-Sweet-Martian-Jewels-ORG_b98p8e_d1c3690f-cf31-4cda-81ff-a5a0d448731a.jpg?v=1773114787","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/martian-jewels-sweet-corn-seeds-customer-review_201.jpg?v=1773114787","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/martian-jewels-sweet-corn-seeds-customer-review_202.jpg?v=1773114787"],"price":4.49,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:02.603Z"},"share_url":"https://firestarter.network/l/lst_7eSGtHT2","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
