{"type":"firestarter.listing","listing":{"id":"lst_rn4RotLa","product_name":"Siberian Kale","category":"Vegetables","description":"THE STORY: As the name suggests, Siberian kale is a cold-hardy kale variety from Northern Asia. Siberian Kale is a treat to grow--easy, productive, and beautiful--and its medium-frilly leaves are extremely versatile: equally useful in cases when you want soft and melting greens as when you want greens that have a little structure and toothsomeness. Best flavor after a frost. USE: Siberian kale is one of the lesser known kales, though you might see it in abundance on supermarket shelves as a baby kale leaf used in salad mixes. While it makes a great addition to salads, you must leave it to grow to appreciate its full potential! The leaves are large, but tender, and only need a quick cooking to make them tender.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Siberian-Kale-vendor-unknown-1630676266.jpg?v=1735580328"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:39.571Z"},"share_url":"https://firestarter.network/l/lst_rn4RotLa","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
