Ubiquitous (& Edible!) Ulva!

Ulva lactuca, more commonly known as "sea lettuce", grows on rocks in shallow tidal pools and along the shores of just about every coast in the world. If you've been to a beach, you've probably seen it and not even known! It's a great name, too, because ulva is as common as lettuce and looks just like it - green, flat leaves with some curling at the ends.

Seaweed in general is quite nutritious and that definitely includes ulva lactuca! Sea lettuce provides protein, vitamins A, B3, B12, C, Calcium, Iodine, Iron, Magnesium, Manganese and Potassium. After it is washed thoroughly, it can be eaten raw in salads or cooked in soups and/or with meats, poultry and fish.



If you're at a beach or a shallow salt water pool, go looking for some sea lettuce! It could make for a great scavenger hunt. You'll be sure to find some other interesting sea plant life, creatures and shells along the way! Happy hunting!


You have quite a few options here. Sea lettuce can be foraged or purchased fresh, and is also for purchase as dried flakes and even as a powder. So, depending on comfort levels and picky palettes, you could find a means to introduce some sea lettuce into a family meal or two! If you go with flakes, you can try this seaweed salad recipe from PBS!  Enjoy!
