'Yellow Sweet Spanish Utah' is from that early type, producing large, 3\"–6\" globe-shaped bulbs with amazingly mild, sweet flavor. A long-day variety, it grows best in states north of the 37th parallel. Utah designated this onion the state vegetable in 2002. Caramelize onions for the perfect patty melt condiment.","images":["https://cdn.shopify.com/s/files/1/0658/5693/0045/files/0291i_Onion-Yellow-Sweet-Span-Utah_190ef146-eb5e-433c-89a3-968ce6dedc6a.jpg?v=1773115448","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/0291si_Onion-Yellow-Sweet-Span-Utah_69eee45f-ad42-464e-b6a3-20da36ce3fb0.jpg?v=1773115448","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/0291w_Onion-Yellow-Sweet-Span-Utah_jc0e5p_92477465-c22d-441d-8766-1c211479ee73.jpg?v=1775679006","https://cdn.shopify.com/s/files/1/0658/5693/0045/files/yellow-sweet-spanish-utah-bulb-onion-seeds.jpg?v=1773115448"],"price":2.69,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:01.988Z"},"share_url":"https://firestarter.network/l/lst_pTh9oLUL","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
