{"type":"firestarter.listing","listing":{"id":"lst_z_tStQTD","product_name":"Tango Celery","category":"Vegetables","description":"Grow this bright green celery if you want prolific, crunchy yields. Great for beginners. For the best celery, start early, side dress with compost, and plant in full sun. Does well in the heat, but keep the soil evenly moist for succulent, crisp stalks. Harvest stalks individually or harvest the entire head. The vibrant, herby leaves add bright flavor to soups and broths; enjoy the stalks with peanut butter or any which way you please. Early maturing.\n ","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Tango-Celery-vendor-unknown-1630682731.jpg?v=1735578911","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Tango-Celery-vendor-unknown-1630682736.jpg?v=1735578911","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Tango-Celery-vendor-unknown-1630682739.jpg?v=1735578911","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Tango-Celery-vendor-unknown-1630682743.jpg?v=1735578912"],"price":5.39,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:37.811Z"},"share_url":"https://firestarter.network/l/lst_z_tStQTD","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
