My husband's favorite crop to grow here in Vermont is lettuce. His favorite lettuce to grow, the one that holds up best for us in both the heat and the cold, is Sierra, a Batavian lettuce from France that is also called Gloire du Dauphiné. For a handful of years, I have been trying hard to find some other varieties of lettuce that are equal to Sierra. Well I finally had success with Rouge Grenoblais! It is a gorgeous lettuce that looked much more beautiful than the picture here shows. For us it had more red color, and more stunning contrast between the red and green parts of the leaves. It held up well in both the heat and the cold. (We will need to grow it for another year to see if it holds up as well as Sierra.) The texture and flavor were excellent. It did not get bitter. A friend of mine is from France. She claims the lettuce that they grow there is much better than here. She might be right. I love this lettuce!
