Lollo Rosso is a loose-leaf variety of lettuce. It has very curly, fan-shaped leaves with bright magenta edges. The leaves grow to a 5- to 8-inch length,  forming a compact rosette. It has a slightly bitter and nutty flavor, so is the perfect balance for sweeter lettuces or dressings.
Lollo Rosso prefers cooler temperatures of 60 degrees and matures in about 60 days.  You can pick the younger, tender leaves when they reach about 3 inches. If you pick the entire outer layer your lettuce will continue to grow and produce more leaves for salads.
