Brought to the U.S. from the British Isles in 1887 by David Murray, gardener for the Marquis of Ailsa, Ailsa Craig heirloom onions are by far the largest onion you can grow in a short growing season. The key is to plant Ailsa Craig onion plants early and never let them slow down. If you are looking for show-size variety with which to win the county fair for largest onion, Ailsa Craig is it. Pump these onion plants up with lots of nitrogen to get them as big as basketballs. Ailsa Craig onions do not store well, so enjoy them soon after harvesting. Also known as the Kelsae Sweet Giant onions.

  1. greentogold77

    These are very large and sweet onions that are reliable in my Montana garden every year. I leave a few of the largest in the ground for next year’s seed, and have been starting them from seed for years. Here they keep for at least two months hanging around in the utility room as we have such a dry climate and they cure well. Some years I order more plants from Dixondale Farms to have enough of these to go around as family and friends love them, too!

    I’ve been growing these onions here in Nebraska for the past 15 years with excellent results. The largest one I’ve grown was over 6 pounds and I’ve won the largest onion in my county fair several times. I have a refrigerator dedicated for onion storage and these onions will keep up to 6 months in the refrigerator.

  3. Jeff Bennett

    I planted my Ailsa’s in January from Dixondale Farms. Most were in the 3 pound range except one. 7.94 pounds. Largest onion I ever had…. So far.

    These onions are very sweet, beautiful, and yummy! In northern New Hampshire, where we can’t expect huge onions, they grow larger than most of the other varieties but not several pounds. A plus: While we expected them not to store well, we ate the last of ours 2 years ago after 5 months of storage. A minus: We harvested fewer onions compared to other varieties. We will plant more this year.

    I’m ordering more for this season as these are some of my favorite crisp, juicy, mild onions perfect for a thick slice on hamburger. Kept in my root cellar they are still good 5 months (currently) after harvest.

    I love these. Big, sweet and gorgeous. And.. mine stored really well all winter (here in the Seattle area!) until late March.

  7. Frank Turner (verified owner)

    Dixondale farms have made me famous for growing giant onions with these Ailsa Craig onions. I live in central Maine and they are grown in raised beds and come out softball size.

  8. Harvey A. Smit

    We’ve grown thousands of Ailsa Craig onions from Dixondale. The onion grows very well in the Pacific Northwest, with an excellent size and superb flavor. Purchasing these onions by the case is a terrific value and the plants arrive in excellent condition. And free shipping to boot! Well done farmers….you’re providing a wonderful product for the folks who come to our produce stand…thanks so much.
