{"type":"firestarter.listing","listing":{"id":"lst_snpALqrY","product_name":"Joker Lettuce","category":"Vegetables","description":"Are plant breeders fools or oracles, magicians or scientists? In the case of Frank Morton, all of the above. Frank is like an entire tarot deck of auspices balancing the known and unknown with the energies of the plants. With each cross, a myriad of possible futures unfolds. Sometimes Frank plays the Joker or the Fool. An uncomfortable place for many, but the perfect milieu for a plant breeder. Out of his deck of traits, he created this entertaining lettuce, destined to become an heirloom of the future.\n This highly adaptable variety will perform well in all growing seasons and has excellent heat and cold resistance. It forms a tight, savoyed head with bold red and pink splashes of color, and is firm and crisp in texture. Harvest from baby-leaf size until the heads are fully mature, at which point they will have a crunchy, sweet core.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Joker-Lettuce-vendor-unknown-1630680395.jpg?v=1735579541","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Joker-Lettuce-vendor-unknown-1630680401.jpg?v=1738085739","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Joker-Lettuce-vendor-unknown-1630680398.jpg?v=1738085739","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Joker-Lettuce-vendor-unknown-1630680404.jpg?v=1735579541","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/FrankMorton_1.png?v=1735579541","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Joker-Lettuce-vendor-unknown-1630680409.jpg?v=1735579541"],"price":5.79,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:38.609Z"},"share_url":"https://firestarter.network/l/lst_snpALqrY","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
