Romaine Lettuce 'Parris Island Cos'

  • Product number: 251040
  • Origin: North America
  • Latin: Lactuca sativa var. longifolia

This tasty cos lettuce produces quite large, uniform heads, which can be harvested both young and fully grown. The dark green outer leaves conceal the tender, yellowish-green interior. This now historic variety was developed around 1949 (by Clemson College's Agricultural Experimental Station, Charleston, South Carolina) and named after the island on the east coast of the US.

Fortunately, cos lettuce is back in the spotlight! We are discovering this crunchy, slightly spicy lettuce as a delicious raw product. Cos lettuce is healthy and grows easily. In the past, the heads were tied together a few weeks before harvesting to make them more tender, hence the name. Nowadays, we are used to the taste and even appreciate a little bitterness in raw vegetables. In the past, this lettuce was even briefly cooked in the Netherlands and thus earned the old nickname "stoofsla" (stewed lettuce). The Romans already ate this lettuce, so it is truly a historic type!
