{"type":"firestarter.listing","listing":{"id":"lst_s4wJVEYW","product_name":"Purple Tomatillo Seeds","category":"Seeds & Plants","description":"Wow! A purple tomatillo! Not only delicious but attractive, too. The purple fruits are much sweeter than the green types and rich in beneficial antioxidants. Let the fruit remain on the plant as long as possible until the husk splits for the best flavor and color. Tomatillos grow best in conditions similar to tomatoes (because they are related) but will handle a lot more heat. Grow two or more plants to ensure good pollination.","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3065i_Tomatillo-Purple-ORG_uqbqix_603cabfa-5dbf-4918-b8b7-ceeccea32500.jpg?v=1773114862","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3065si_Tomatillo-Purple-ORG_f584c2f3-733a-4b85-8975-020c40c446d9.jpg?v=1773114862","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3065w_Tomatillo-Purple-ORG_5452971d-bd60-41f7-a843-de121dcfda1b.jpg?v=1775678937","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/purple-tomatillo-seeds.jpg?v=1773114862"],"price":2.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:02.402Z"},"share_url":"https://firestarter.network/l/lst_s4wJVEYW","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
