Lettuce Parris Island
Lettuce Parris Island
Flavourful pale centres are surrounded by thick green outer leaves on enormous upright plants. Parris Island Cos romaine lettuce seeds can be planted close together for a long harvest of little leaves for gourmet salads. Given space and time to grow to full size, Parris Island forms huge heads up to 30cm (12") tall, but even at this crazy size, the leaves are tender and succulent, with mild flavour.

Timing
Lettuce grows best in cool weather in the spring and fall, but it can be grown in the summer, and all winter long in milder regions. Sow short rows every 2-3 weeks following the last average frost date for a continual harvest. Using a cloche, cold frame, or greenhouse over mid-late summer plantings can extend the harvest period right into winter. Optimal soil temperature for germination: 10-22°C (50-72°F). Seeds should sprout in 7-15 days, depending on conditions. Lettuce seeds don’t sprout easily when the soil temperature is over 22°C (72°F) in summer. Get around this by sprouting them indoors in a cool area, or pre-sprout by sprinkling seeds on a damp paper towel and placing it in a plastic bag in the fridge for a few days. In hot weather most lettuce goes to seed rapidly, so have new plantings ready to go, and watch for "good resistance to bolting" in the product description.
