Lettuce, 'Parris Island Cos'

That’s Parris Island, South Carolina not Paris, France. Bred by the USDA and Clemson Ag Extension in 1952, Parris has stood the test of time as a classic, big, market-quality romaine. We’ve sold this to restaurants for Caesar salads, and to supermarkets by the case. Excellent texture, crunch, and vigorous upright habit. Dark green, uniform, productive workhorse romaine. Some resistance to tip burn.

Medium. Prefers well-drained, and evenly moist soil and is sensitive to low pH.


Uneven watering can result in tip burn, the browning of the leaf margins, which is the result of an inability of the plant to move calcium to the growing edge fast enough to meet its growth needs. Consistent, evenly moist soil or calcium amendments can be beneficial if this seems to be a problem.

Hot weather can cause premature bolting. Generally, when the plants begin to stretch upwards (to flower), the leaves become bitter and the eating quality poor.
