55 days — Also known as 'Prize Head' and 'Early Prize Head'. Despite its name, it is a non-heading, leaf or loose-headed lettuce variety. The leaves are upright, deeply curled, broad, and light green with a slight reddish blush on the tips. Along with being quick to harvest, it is a fine sort and is slow to bolt to seed. This variety produces luscious slow bolting heads of loose, large green leaves with curled maroon tips.
