Lettuce, Greek Maroulli Cos (Organic)
Lactuca sativa. Green Romaine. 30 days baby; 60 full.
A solid, medium-sized, bright green romaine lettuce. Forms crunchy leaves and tall heads. Many of the heads will form multiple hearts. We thought at first that we should select away from this trait, however we found it to be a fantastic trait for romaine heart production and easy cutting salad mix. There are new patented lettuce varieties on the market that have similar traits to this and we believe that utility patents on natural traits that have existed for centuries to be outrageously corrupt. Here you will find some of the “prior art” of the plant world, to borrow some patent legalese. Originating in Greece, which is where romaine/cos type lettuces were presumably developed.

Sow indoors in flats with good potting soil year-round. Transplant into the garden 3-4 weeks after sprouting at 3″ spacing for leaf, 12″ for heads. Alternatively, direct sow March through September. In our area, lettuce can go through winter if protected. Succession sow for continual harvest.
Seed Saving
Collect seeds when flowers are downy like dandelions. Cut seed heads and place upside down in a paper bag to dry for a few days. Knock seed heads against side of bucket or tote, rub downy fluff off seeds. Winnow and screen to clean.

Where did you grow this variety? Canada
I grew this for the first time in 2024 and again now in 2025. Both years planted out April 21. Second batch planted May 15. This lettuce grows enormous and the outer leaves are good cooked as greens or Greek pork fricassee. The hearts are of course great in salad.
Grown in Toronto, Ontario, Canada
