Lollo Rosso, also known as Lollo Rossa, falls into the loose-leaf variety of lettuce. It has very curly, fan-shaped leaves with bright magenta edges. As the leaves grow to their 5- to 8-inch length, they form a compact rosette. This lettuce has a slightly bitter and nutty flavor, making it the perfect balance for sweeter lettuces or dressings.
Lollo Rosso prefers cooler temperatures of 60 degrees to 65 degrees, and it matures in about 60 days, although you can pick the younger, tender leaves when they reach about 3 inches in length. Be sure to pick the entire outer layer, and your lettuce will continue to grow and produce more leaves for your salads.
