{"type":"firestarter.listing","listing":{"id":"lst_QaemN9RT","product_name":"Australe Butterhead Lettuce Seeds","category":"Seeds & Plants","description":"It's hard not to love this easy-to-grow lettuce. The stunning bright green leaves are dusted with almost iridescent bronze tips. \"Australe\" reminds us of a cross between a traditional butterhead due to its buttery texture and a mini romaine because of its upright growing habit. Harvest as baby greens around 21 days or as a full head at 55 days.","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3271i_Lettuce-Butterhead-Australe-ORG_i79qkk_2c41904d-638a-4d5a-980d-dc925d7156a5.jpg?v=1773102450","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3271si_Lettuce-Butterhead-Australe-ORG_e9ea3c99-d7a5-4dfb-8709-71a155aa7674.jpg?v=1773102450","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3271w_Lettuce-Butterhead-Australe-ORG_jxg6en_245188f7-ed58-4adf-96d8-b6efe91da196.jpg?v=1773102450","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/australe-butterhead-lettuce-seeds.jpg?v=1773102450"],"price":2.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:01.678Z"},"share_url":"https://firestarter.network/l/lst_QaemN9RT","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
