{"type":"firestarter.listing","listing":{"id":"lst_KQ6u_lPu","product_name":"Red Giant Mustard","category":"Vegetables","description":"Mustards are underappreciated in the garden. This Asian variety is robust and beautiful. Its leaves are green with a deep purple hue, thin and very soft when steamed or sautéed. Its slight bite adds a pleasant tangy ring to any meal, complementing grains beautifully. Extremely easy to grow--and fast! Stays more mild flavored in cool weather; does quite well into late fall.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Red-Giant-Mustard-vendor-unknown-1630676176.jpg?v=1735580345","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Red-Giant-Mustard-vendor-unknown-1630676179.jpg?v=1735580345","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Red-Giant-Mustard-vendor-unknown-1630676183.jpg?v=1735580345"],"price":13.79,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:39.607Z"},"share_url":"https://firestarter.network/l/lst_KQ6u_lPu","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
