{"type":"firestarter.listing","listing":{"id":"lst_154JP4yx","product_name":"American Flag Leek","category":"Vegetables","description":"Although, with a little imagination and a lot of squinting, this leek could look red (light pink flowers), white (blanched bottoms), and blue (green-blue leaves), it's a bit of a stretch. Originally called the Flag Leek because its tall, broad stem resembles a miniature but sturdy flag pole, its title was later decorated with a dose of patriotism somewhere along the way. This variety produces heavy, tall, wide stalks that sweeten up in the fall/winter.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/American-Flag-Leek-vendor-unknown-1630676865.jpg?v=1735579879","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/American-Flag-Leek-vendor-unknown-1630676867.jpg?v=1735579879","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/American-Flag-Leek-vendor-unknown-1630676870.jpg?v=1735579879"],"price":4.39,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:39.304Z"},"share_url":"https://firestarter.network/l/lst_154JP4yx","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
