Oak Leaf Lettuce is perfectly described in its name! This variety features deeply lobed bright green oak leaf shaped leaves that are deliciously tender and sweet without any bitterness in their flavor. Typically grown for baby-leaf lettuce production, the mature full size heads grow to be 7" to 9" inches and are equally tasty. Known for its heat tolerance, Oak Leaf lettuce is well suited to grow all summer long. 50 days. Packet: approx. 500 seeds.
