(51 days) Red Fire is gaining popularity with market growers. Beautiful, frilly red-edged leaves with a fresh bright green base and interior form a heavy head that makes attractive, tender salads.

Red Fire is relatively slow but produces uniform, heavy heads of well-colored, frilly leaves. This lettuce has been almost the last to flower, sometimes lasting as late as July 29 in northern regions. It's also very cold-hardy and does well through most of the winter in tunnels in northern regions. Its tender and sweet flavor have very little to no bitterness. Resists BOR, DM, TB.
