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.  Spanish Sweet Yellow's intermediate-day photoperiod requirement provides geographic flexibility, enabling successful cultivation across moderate climates where traditional long-day varieties struggle. Expect mature, harvestable bulbs in approximately 100-120 days under favorable conditions.

Germination Rate: 85%. Test Date: 8/25. OME
