Brought to the U.S. from the British Isles, this heirloom onion is by far the largest onion you can grow in a short growing season. If you are looking for show-size variety with which to win the county fair for largest onion, this is it. Pump these up with lots of nitrogen to get them as big as basketballs. Also known as the Kelsae Sweet Giant.

Out of Season

The total price of your onion plant order will be determined at checkout. Pricing is based on the total number of bunches purchased (see chart to the left).

Every time I went out to the garden I would LOL (laugh out loud) at the size of these giant freak onions! All were over 1.5 lbs with some 2.5 pounders! Well done Dixondale Farms!!
Much Better than expected

I don't live in a long day area and these are long day onions. Nevertheless, I've had great results. We get at most 14.5 hours of daylight here which was enough to trigger the plants to produce bulbs. I don't like these as much as Candy, but the size is larger. Really, I just wanted to see if they would grow here in central North Carolina...and they do.

I love growing Ailsa Craig, simply for the bragging rights for the largest onions. I have grown them for about 15 years, and generally they store for me for about 4 months.Fargo, ND

I have been growing the Ailsa Craig for several years and they seem to keep longer each year. We had a cold winter this year and my Ailsa Craig's keep very well. I just used my last one today March 7th. They say they will only keep 1 month but mine are 7 months old and are as good as the day they were harvested. My only wish is that I would have planted more.Burlington, Washington
Simply Delicious!

My new favorite! They did great growing in Michigan even in a colder than average summer that lacked the usual sun. Hart, Michigan

Storage time on these onions is way better than advertised, planted one bundle last season, got a late start did not plant until June, grew well and just had the last one in a salad in February- Clearfield, Pa
Ailsa Craig love them

I grow several kinds of onions each year but the Ailsa Craig are the biggest. Most are 6" to 8" in size. We are still eating last years crop. They are keeping good and this is mid January.Burlington, WA

I have planted Ailsa Craig onions for the past two years. They wasn't the best summer for gardens, but the onions were very good in flavor. The mild onions are good in salads and can be eaten raw just like an apple. The rainy summers meant that storage was short month. But I will be buying them again as they are worth it. Erie, Pa
Amazing onions 
posted by Cheryl Indiana on 2014-07-12 17:08:57
These onions outsized my walla walla, candy superstar red river and ringmasters. Plenty of organic matter, rain and good draining soil. All my friends are amazed how big these got and how sweet they are. Onions the size of softballs and tops with a diameter of two+ inches. Planted them 6 inches apart and they grew to almost touch each other. A must for next year. Doubling my order. Indiana

I was disappointed in these onions. I planted in August for a winter crop; they did noting. In the spring (April) they put big fat seed heads; I finally pulled the and they were more like small leaks; no onion.

I anticipated monster onions. I already know how to grow large veg. I was disappointed in the size. All hit 2 pounds and stopped. Of course it could be the historic drought and record breaking high temps! I will try them again next year. Thanks Dixondale Farms. Mark in Indiana

These are such wonderful onions! I sliced them in half top to bottom and grilled them (the REALLY big ones got quartered). Real crowd-pleasers.New York NY
Aisle Craig onion-outstanding 
posted by Keith Evenson on 2011-09-29 10:00:29
My neighbor order Aisle Craig onions to sell at the 'farmers market'-he sells hundreds each week-many to same people week after week. The past two years he has given me 2 bunches to raise in my small (6x10') raised garden. The first year I planted them too close (3") and they grew into each other. This year I planted them 4" and it was perfect. I give so many out to my neighbors, friends, and relatives and every one of them rave how sweet and wonderful they are. They keep in my garage until about Christmas and then they are gone. Thanks for a great product and highly recommend to all.
biggest and best

Ailsa Craigs are always the biggest and sweetest onions three years running in my garden in Seattle I will grow this instead of walla wallas in my limited garden space in the future.

I thought I would drop you a line and thank you for the great plants this last spring. I grew a bunch and gave away lots of onions. I want to tell you some thing about the Ailsa Craig Onion that you sell. It will keep a lot longer than what your flyer indicates (one month) I still have the aisa craig in my basement and a couple of other friends that grew them still have them to. They really seem to keep at least 3-5 months. So I would change the one month to 2-3. More people would try them. The aisa craig is a really great onion. PS. you will see my order soon.

Our Biggest Hit!!

We had more comments about the Ailsa Craig onions last summer as customers came to buy! They had never seen such big and beautiful onions. The taste also matches what they see. It is a versatile sweet onion. We have raised and sold produce for 31 years and this is the BEST one I have ever seen!! Check our website at for pictures of Ailsa Craig!
Fantastically Sweet

First tasted this brand from a man selling them off his truck. He told us what they were and where to buy. Our 1st crop last year weren't as big as his large grapefruit size but they were wonderful. They keep well in a refrigerated environment as I still have some (Jan). So good sliced in butter, covered with paper towel and put in the microwave. Sread on a baked potato. Yummy! Now we have to get his secret to BIG ONES.
Great Onion eh!

This is the best onion plant that you can buy, that I know of for the north. I live in North Dakota near the Canadian border. With good sun and a little lake water, this type of onion, will on average, grow up to 2-3 pounds. Big one's 4+.

We gave her a few of our plants to try. She had a 2# onion and raved about the taste. She'll be ordering for her very successful vegetable stand next year.
