This non-GMO variety produces characteristically large, uniformly round bulbs with pale yellow exterior skins and crisp white, juicy flesh that develops remarkable sweetness as bulbs mature. The substantial bulb size and superior flesh quality make Spanish Sweet Yellow exceptionally valuable for both fresh consumption and diverse culinary applications. The variety's mild, naturally sweet flavor profile distinguishes it from conventional pungent onion types, making it exceptionally versatile for raw applications where flavor subtlety matters. The tender flesh and refined taste excel in fresh salads, salsas, and other preparations where onion character should complement rather than dominate. The variety's culinary sophistication makes it equally suitable for cooked dishes where the sweet flavor develops further through caramelization and extended cooking. Spanish Sweet Yellow's intermediate-day photoperiod requirement provides geographic flexibility, enabling successful cultivation across moderate climates where traditional long-day varieties struggle. The variety's adaptability to diverse growing conditions and moderate climate preferences reduces cultivation challenges while supporting reliable, consistent performance. The excellent storage capacity enables season-long enjoyment of fresh onions, with properly cured bulbs maintaining quality and flavor integrity for extended periods. Expect mature, harvestable bulbs in approximately 100-120 days under favorable conditions, enabling strategic planting timing and succession cultivation. These seeds are non-GMO certified, and our commitment to sustainable cultivation and environmentally responsible, recyclable packaging, Spanish Sweet Yellow offers comprehensive value for gardeners seeking heirloom onion performance combining exceptional flavor quality, reliable productivity, and versatile culinary applications across diverse preparation methods.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eWhy Choose Onion Intermediate Day Spanish Sweet?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Use:\u003c\/strong\u003e Ideal for fresh eating in salads or salsas, and perfect for cooking in soups, stews, and sautés.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRich in Flavor:\u003c\/strong\u003e Sweet, mild flavor with a juicy texture, perfect for those who prefer a less pungent onion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardy \u0026amp; Adaptable:\u003c\/strong\u003e Thrives in intermediate-day length climates, making it ideal for a wide range of growing regions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong-Lasting:\u003c\/strong\u003e Known for excellent storage qualities, allowing you to enjoy homegrown onions for months after harvest.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSustainable Packaging:\u003c\/strong\u003e Non-GMO seeds in reusable, recyclable, and climate-friendly packaging.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003ePlanting Tips for Success\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunlight:\u003c\/strong\u003e Prefers full sun for optimal growth and bulb development.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e Grows best in fertile, well-drained soil with plenty of organic matter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlanting:\u003c\/strong\u003e Start seeds indoors and transplant outdoors once the danger of frost has passed or sow directly outdoors in spring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacing:\u003c\/strong\u003e Space seeds 4-6 inches apart for optimal growth and bulb formation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWatering:\u003c\/strong\u003e Water regularly to keep soil consistently moist but avoid over watering to prevent root rot.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eWhy Choose David’s Garden Seeds®?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVeteran-Owned:\u003c\/strong\u003e Supplying premium seeds since 2009.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGO TEXAN Certified:\u003c\/strong\u003e Supporting local agriculture and communities.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeirloom Seed:\u003c\/strong\u003e Passed down for generations, ensuring superior flavor and consistent growth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFreshly Packed:\u003c\/strong\u003e Packed for the current growing season with high germination rates.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3 style=\"text-align: center;\"\u003eOrder Spanish Sweet Onion Seeds Today\u003c\/h3\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(235, 24, 24);\"\u003e\u003cstrong\u003eOrder today and grow your own fresh Onions in your spring \u0026amp; fall gardens. \u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"David's Garden Seeds®","offers":[{"title":"50 Seeds","offer_id":46936905515265,"sku":"b3 0058WILL-1","price":0.96,"currency_code":"USD","in_stock":false},{"title":"100 Seeds","offer_id":46936905548033,"sku":"0058WILL-2","price":1.46,"currency_code":"USD","in_stock":true},{"title":"200 Seeds","offer_id":46936905580801,"sku":"0058WILL-3","price":1.96,"currency_code":"USD","in_stock":true},{"title":"400 Seeds","offer_id":46936905613569,"sku":"0058WILL-4","price":2.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0570\/4659\/7796\/files\/onion-spanish-yellow.png?v=1763740047"},{"product_id":"pelleted-seed-onion-long-day-patterson-4-sizes-available-copy-1","title":"Pelleted Seed Onion Intermediate Day Monastrell 4 Non-GMO, Hybrid Seed Sizes Available","description":"\u003cdiv class=\"description collapsible-xs\"\u003e\n\u003cdiv class=\"description collapsible-xs\"\u003e\n\u003cdiv class=\"description collapsible-xs\"\u003e\n\u003cp id=\"collapsible-description-1\"\u003e\u003cspan style=\"color: rgb(243, 9, 9);\"\u003e\u003cstrong\u003ePelleted Seed Onion Intermediate Day Monastrell\u003c\/strong\u003e\u003c\/span\u003e red onion delivers exceptional performance for late-season production across diverse growing regions.
