Also known as French crisp or Batavia lettuce, summer crisp types are easy to grow, relatively tolerant of hot weather, and harvestable from baby-leaf to full size. Very crisp like romaine, but sweet and juicy, without bitterness. The shape of the summer crisp plant is at first open, much like a loose-leaf lettuce, then matures into a heavy, compact bunch or head. Summer crisp lettuces perform best given slightly more fertility than loose leaf types.
