{"type":"firestarter.listing","listing":{"id":"lst_ZWiH3VoY","product_name":"Mizuna Mustard Seeds","category":"Seeds & Plants","description":"A graceful plant in flower beds and containers, and also a tender, mildly spicy, Japanese mustard green that is milder than other mustards, and ready to harvest in as little as 3 weeks as tender baby greens. Beautiful and prolific, and withstands heat longer than lettuce without bolting. Use fresh in salads, steam, or stir-fry. Seeds will germinate under cold and wet spring conditions.","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3047i_Mustard-Greens-Mizuna-ORG_5xhn5z_2ec67f4d-3395-4983-b7c5-482c70a3dfb6.jpg?v=1773114524","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3047si_Mustard-Greens-Mizuna-ORG_b86020fe-eb13-4ec1-9615-dade747fa1d7.jpg?v=1773114524","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/3047w_Mustard-Greens-Mizuna-ORG_n2l8ry_9b3bfcc5-fc1e-4e43-a003-748e1385ec22.jpg?v=1775678897","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/mizuna-organic-mustard-seeds.jpg?v=1773114524"],"price":2.69,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:02.578Z"},"share_url":"https://firestarter.network/l/lst_ZWiH3VoY","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
