Crunchy, sweet leaves, buttery-green heart, and vigorous growth are a few ways to describe 'Parris Island Cos' romaine. Developed by the USDA and Clemson University around 1950, this nutritional, 10"-12", upright lettuce will soon be a favorite in your garden and your kitchen, full grown or as a baby green in as little as 21 days. Ideal for lettuce wraps. Plants resist tipburn and are mosaic virus tolerant.
