Onion Long Day Ailsa Craig Exhibition is a venerable heirloom variety originating from Scottish breeding traditions, renowned for producing exhibition-quality bulbs of remarkable size and aesthetic appeal. This non-GMO variety generates jumbo to colossal bulbs with distinctive round to teardrop-shaped forms and attractive light brown exterior skins that develop character and visual interest. The impressive bulb dimensions and refined appearance make Ailsa Craig Exhibition equally valuable for competitive exhibition and practical home cultivation. The variety's long-day photoperiod requirement makes it ideally suited for Northern regions and cool-climate areas where extended daylight periods during growing seasons trigger reliable bulb development. This physiological adaptation ensures consistent, predictable bulbing even in regions with extended summer daylight, eliminating the frustration of failed bulb formation that challenges gardeners attempting to cultivate unsuitable varieties. The natural alignment between variety requirements and regional growing conditions supports reliable, high-quality production. Ailsa Craig Exhibition's characteristically mild flavor profile and tender flesh distinguish it from pungent onion varieties, making it exceptionally versatile for fresh consumption where subtle flavor matters. The substantial bulb size and superior flesh quality deliver impressive yields from compact plantings. The variety's excellent fresh-eating characteristics and short-term storage capacity enable season-long enjoyment of premium onions, with properly handled bulbs maintaining quality for several weeks. Expect mature, exhibition-quality bulbs in approximately 110 days under favorable conditions, enabling strategic planting timing and harvest management. The germination rate of approximately 80% or better ensures dependable seed establishment. With 200 seeds per packet, non-GMO certification, and our commitment to sustainable cultivation and environmentally responsible, recyclable packaging, Ailsa Craig Exhibition offers comprehensive value for Northern gardeners seeking legendary exhibition onion performance combining exceptional size, refined flavor, and reliable productivity.
