My Mesculn Garden lettuce

Here on the farm we grew many kinds of lettuce.
Mesculin mix is a term used in Southern France varieties that have a bold flavor, like Arugula, Radichio, different mustard greens, Spinach and other leafy greens. These of course wouldn’t be great for a lettuce wrap, but you can include them in the filling of a milder lettuce to add flavor and texture.

From Wikipedia:

The term mesclun for a mixture of young salad greens is quite recent, according to the Merriam-Webster Dictionary first used in 1976.[1] Of Provençal dialect origin, it derives from the verb mesclar, to “mix thoroughly” and literally means “mixture”.[2] According to local lore, mesclun originated with the farmers around Nice, who would each bring their own unique and prized mix of baby greens to the farmers’ markets. One of the most representative and authentic versions combined baby dandelion, lettuce and rocket (arugula).[3]

Noted chef Alice Waters comments, “Outdoor markets in Provence display mesclun in profusion, a melange of the first tender young leaves which appear in the garden. Mesclun can be an extraordinary lettuce mixture: rocket, much like the rugola (arugula) found in Italian markets, chervil, mâche or lamb’s lettuce and oak leaf. On occasion, baby curly endive (chicory) or young dandelion greens find their way into the medley, depending solely upon the grower’s personal preferences combined with the reality of whatever else might send up shoots in the spot where mesclun grows.”[4]

These are some of the varieties of Mesculin mix we grew.
