Up to 5 lbs bulbs! Relatively mild and sweet, recommended for fresh use
Long day type - Very well-known globe-shaped heirloom onion that reaches really huge size - 5 lbs is rather common! The skin is a pale yellow and the flesh is relatively mild and sweet, so is recommended for fresh use—not a storage type. Introduced in 1887 by David Murray, gardener for the Marquis of Ailsa, at Culzean Castle in Maybole, South Ayrshire, Scotland.Amaryllidaceae Allium cepa
The sweet onions are low in sulfur and high in water, which gives them such a mild flavor they can be eaten raw. They also have thin skins and so don't store very well.

Correct timing is important with bulb onions, if you don't plant them at the right time they won't do very well. The best onions are grown from transplants set out in October or November and wintered over to mature in June and July. Plant transplants right away, if possible. Transplants are happy if you apply a light mulch to help conserve moisture for uniform growth.
