Onion Intermediate Day Spanish Sweet Yellow is a distinguished heirloom variety with deep historical roots in Mediterranean onion cultivation, delivering exceptional flavor complexity and reliable performance across intermediate-day growing regions. 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.
