Long Day- Originating in Scotland, Ailsa Craig Onions have yellow/brown skin. They are known for their stunning flavor and size. These giant sweet onions are known to grow 1-2 pounds a piece, sometimes up to 5lbs! Recommended for fresh eating as these don't have the longest shelf life.
I have trouble growing large onions. So far these onions have grown the largest for me.
Great germination and amazing flavor
So excited to plant these onion seeds soon!
Best price anywhere and the best quality seeds!! Looking forward to the 2026 growing year!
Grew these for the past three years and I will keep growing them for many more. I highly recommend them. Great germination rate. Every onion grew to the size of baseballs and others a bit bigger and they store very well.Best long day onion I have ever grow.
I am very happy with my heirloom seeds. I cannot wait to germinate them.
Started my seeds on 12/31/25. I’ve had almost 100% germination and the onion seedlings are a couple of inches tall at this point (1/9/26). Looking forward to a great harvest!
Grew these last year, so I bought more seeds! they were awesome, very prolific and tasted great!!
I started them early....did waterjug winter seed starts .. they did very well....grew up to be nice sturdy plants, bearing lots of fruit! Thank You!!
