{"type":"firestarter.listing","listing":{"id":"lst_eQXLlZFC","product_name":"Candy Stevia Seeds","category":"Seeds & Plants","description":"Now you can grow your own calorie-free, carbohydrate-free, low-glycemic sweetener at home! Stevia, also called sweetleaf, is up to 300 times sweeter than sugar, so a little goes a long way. Some say the leaves have a slight, pleasant, anise aftertaste. The bushy, 18\"-30\" tall plants can be grown in 10\"-12\" diameter containers. Leaves are sweetest just before the plant flowers in late summer to fall. Grown as an annual, although perennial in USDA zones 10 and warmer.","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/6128i_Stevia-ORG_l6hsra_98e94e63-b911-4a31-90ea-0d24cf17cf16.jpg?v=1773115672","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/6128si_Stevia-ORG_8ea083a8-1f4c-4209-9d95-47a50d89e908.jpg?v=1773115672","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/6128w_Stevia-ORG_mxh2n7_f955ea6a-fa08-4714-8fcb-a97f0a4621a4.jpg?v=1773115672","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/stevia-seeds.jpg?v=1773115672"],"price":4.49,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:03.254Z"},"share_url":"https://firestarter.network/l/lst_eQXLlZFC","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
