Lettuce, Romaine, “Little Gem” Seeds

Lactuca sativa

Category: Tag:

Organic, Heirloom.

Also called ‘Sucrine’ or ‘Sugar Cos’, ‘Little Gem’ is an English heirloom that is a small variety of romaine, but has the succulent sweetness of a butterhead. The glossy-leafed heads are a petite, 6″ tall and 4″ wide—the perfect size for an individual dinner salad. The tender, blanched heart is ideal for any recipe that calls for “hearts of romaine.”

This 1 gram packet sows up to 114 feet.
