This is my first year raising Copra onions, and they are pretty much what I had expected from reading about them. They are small, usually no more than 3 to 4 inches in diameter at most. But, I grew them for winter storage -not size. A quote from the supplier reads, "This is the best storage onion available. Its extra-hard medium-size bulbs will provide you onions for cooking until you have to plant again. The blocky round shape and thin necks allow the onions to dry quickly and they still have the highest sugar content of any storage type." Unquote. My supplier is Dixondale Farms, and they are very favorably rated in the Garden Watchdog.

It did not get as big as I thought it would; most turned out very small. They do last well, and it is nice to have onions from the garden for most of the year.
