{"type":"firestarter.listing","listing":{"id":"lst_YO-nI8dH","product_name":"Rainbow Tatsoi","category":"Vegetables","description":"This colorful and cold-hardy Asian Green has its roots in human error. Dan Brisebois, of the Tourne-Sol Cooperative Farm outside Montreal, discovered that a mislabeled seed variety had led to an accidental cross-pollination among his tatsoi. But discerning some beautiful traits in the off-types, he set about deliberately selecting for the colorful pink stems and purple foliage that had appeared.\nRainbow is a lovely, deep green tatsoi with vibrant splashes of purple, red, and pink. Mature heads develop to a rosette of sweet and mild leaves that can be used in salads and sautés. The plants develops a burnished purple hue when touched by frost.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/1A28E3A9-E697-43A3-9BCF-1349F7167E01_1.jpg?v=1735579428","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Rainbow-Tatsoi-vendor-unknown-1630681740.jpg?v=1735579428","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Rainbow-Tatsoi-vendor-unknown-1630681737.jpg?v=1735579428","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/73D62A00-0EB4-4A2B-A598-3DC04EA68724_1.jpg?v=1735579428","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/21728460-63D6-4BF6-89C7-5F690DBC87EC_1_1.jpg?v=1735579429"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:38.150Z"},"share_url":"https://firestarter.network/l/lst_YO-nI8dH","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
