{"type":"firestarter.listing","listing":{"id":"lst_A-_V6ZO_","product_name":"Parris Island Cos Lettuce","category":"Vegetables","description":"Parris Island is in coastal South Carolina, in a climate that is not all that favorable for lettuce cultivation. This variety, which is named after the spot, puts up with the strains of heat and drought and not-so-perfect soils. Its upright romaine habit keeps it chugging into summer without bolting. A great choice, too, for early-summer sowings intended for baby-leaf harvest.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Parris-Island-Cos-Lettuce-vendor-unknown-1630676068.jpg?v=1735580362","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Parris-Island-Cos-Lettuce-vendor-unknown-1630676065.jpg?v=1735580362"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:37.618Z"},"share_url":"https://firestarter.network/l/lst_A-_V6ZO_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
