52 days. Outredgeous is a wonderful, stout-growing variety that can be harvested as either as a baby lettuce or allowed to mature as a 10 inch romaine. The thick, glossy, slightly ruffled leaves are bright red on top, fading to a pale rouge at the base. Serve as a head lettuce with its sweet crispy heart drizzled with seasoned olive oil. If you are a market grower, this lettuce is best banded for market sales. Originally selected by Frank Morton.
