{"type":"firestarter.listing","listing":{"id":"lst_TBlJ-NXM","product_name":"Speckled Roman Tomato","category":"Vegetables","description":"Indeterminate. A contemporary heirloom with beautiful yellow streaking on red fruits, Speckled Roman is the result of a stabilized cross between Banana Legs and Roman Candle. It boasts the typical shape of tomatoes in the \"paste\" category, long and slender like a horn pepper. Like other good \"processing\" tomatoes, Speckled Roman has a great, tangy tomato flavor, is on the drier side, quite meaty, with few seeds. Harvesting these is quite a treat and they add a nice touch to other colorful heirloom varieties. Nice yields make it suitable for market growers as well--the fruits are very compelling!","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Speckled-Roman-Tomato-vendor-unknown-1630677543.jpg?v=1735579816","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/speckled_roman.png?v=1739840797"],"price":4.39,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:39.019Z"},"share_url":"https://firestarter.network/l/lst_TBlJ-NXM","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
