{"type":"firestarter.listing","listing":{"id":"lst_1SipI_FS","product_name":"Ace 55 Bush Tomato Seeds","category":"Seeds & Plants","description":"A 1950s heirloom, 'Ace 55' has excellent, fresh tomato flavor and is a lower-acid tomato. An old favorite for canning, 5\"–6\" diameter, 6–8 ounce fruits are just the right size to quarter and pack into jars. Yields are exceptional; as a determinate type, the majority of the fruits ripen over a 1 to 2 week period. In areas with a long growing season, sow in succession.","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3039i_Tomato-Bush-Ace-55-ORG_mxu7si_1beed738-0dc5-4384-99e4-cba467e3c3e3.jpg?v=1773102533","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3039si_Tomato-Bush-Ace-55-ORG_1f876fc6-28bc-4d10-8103-2104f9e10870.jpg?v=1773102533","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3039w_Tomato-Bush-Ace-55-ORG_6d9cfe2e-8574-45d5-aaa7-f37bebc007aa.jpg?v=1773102533","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/ace-55-bush-tomato-seeds.jpg?v=1773102533"],"price":2.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:03.588Z"},"share_url":"https://firestarter.network/l/lst_1SipI_FS","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
