In Spanish "cogollos" means heart or something like that. In Spain on local menus it refers specifically to the hearts of a particular kind of lettuce. Small dense hearts about 2 inches in diameter and 4-5 inches long, pale in the center to darker green outside.
Does anybody know exactly which variety of lettuce this is?
I'd like to grow it but can't find any reference to seeds associated with cogollos on the internet. Thanks.
