The shape of this lettuce’s leaves is similar to that of the oak tree, thus, its name. It has colorful borders of autumn and red shades and it is used as a garnish. The leaves have a mild, sweet, tangy, and nutty flavor. This delicate, tender lettuce acts as a great bed for other ingredients and won’t compete with other flavors. This type of lettuce goes well with any vinaigrette. Oakleaf lettuce is rich in minerals and vitamins A, vitamin B, vitamin C, vitamin D, and vitamin E.
