{"type":"firestarter.listing","listing":{"id":"lst_cPMcMF9C","product_name":"Perpetual Spinach Swiss Chard Seeds","category":"Seeds & Plants","description":"Despite its name, \"Perpetual Spinach\" is actually a type of Swiss chard. An old, Italian heirloom, this variety is also known as 'Bietola a Costa Fine' which means 'Swiss chard with thin ribs' in Italian. Becuase it is slower to bolt in hot weather, this variety is a perfect choice for warmer climates. Great as both baby greens and full size. Buon appetito!","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/0378i_Swiss-Chard-Perpetual-Spinach_2026.jpg?v=1773114959","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/0378si_Swiss-Chard-Perpetual-Spinach_ae04c071-d7e9-4303-ad44-f972f3522aad.jpg?v=1773114959","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/0378w_Swiss-Chard-Perpetual-Spinach_tt5b52_9326b086-da96-45eb-a624-179d8bd6bf69.jpg?v=1773114959","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/perpetual-spinach-swiss-chard-seeds.jpg?v=1773114959"],"price":2.69,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:01.620Z"},"share_url":"https://firestarter.network/l/lst_cPMcMF9C","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
