Onion Long Day Red Rock stands as the premier red onion choice for southern growers, delivering markedly uniform, vibrant red bulbs of impressive jumbo size with classic globe shape. The gorgeous, rich skin color extends throughout the internal rings, creating striking visual appeal whether sliced fresh or cooked. These disease-resistant hybrids combine intermediate resistance to Fusarium Basal Rot and Pink Root with exceptional sweetness and ease of cultivation. Red Rock excels as a short-day variety, making it ideal for overwintering in the South with fall planting for spring harvest, or for Southern California's unique growing conditions. Northern gardeners can also overwinter these seeds for beautiful globe-shaped spring bulbs, though maturation occurs later than Desert Sunrise varieties. Individual bulbs reach up to one pound at full maturity, providing substantial yields from compact garden space. With a 110-day harvest window and 80% or higher germination rate, you'll achieve reliable, predictable results. While best enjoyed fresh or for short-term storage up to three months, Red Rock's superior flavor profile and disease resistance make it invaluable for both home gardeners and market growers. These non-GMO hybrid seeds are backed by sustainable practices and environmentally responsible packaging—reusable, recyclable, and climate-conscious—reflecting our commitment to quality and stewardship.
