For truly enormous onions, choose Kelsae sweet onion seeds. This HEIRLOOM cross of two exhibition onions was developed in Scotland in the 1950s. Kelsae is a sweet, mild, white onion of the long day variety, suited to growing in northern regions. In 1995 one grower managed the world record of the largest onion ever grown at 16 lbs, 8 1/2 oz. Most growers will not achieve this size, but the bulbs will certainly be large. Kelsae keeps well into the following year. Although it was the result of a crossed parentage, Kelsae is not a traditional hybrid. It will produce viable seeds for seed saving.
Matures in 110 days. (Open-pollinated seeds)
