Paris Island Cos Lettuce seed Lactuca sativa
LATIN NAME: LACTUCA SATIVA
COMMON NAME: Cos Lettuce
The cos lettuce nests the crisp, upright annual with the firm, spoon-shaped, deep-green leaves that fold together into the tall, upright head, the outer leaves spreading and the inner leaves nesting into the tight, blanched heart, the small, yellow flower heads following on the tall stem if the plants run to seed. The plant grows quickly from the seed, and it likes the sun, and the rich, moist, well-drained soil.
Scientific Research & Plant Biotechnology
The crisp, upright heads of the cos lettuce hold a long place in the research on the leafy salad crops of the daisy family, and the sativa species appears in the studies of the head formation and the leaf nutrition. The work looks at the way the inner leaves blanch into the tight heart, the fast cool-season growth, and the seed biology. The food scientists value the crisp texture, and the growers of the salad vegetables keep the species in their catalogues.
Ecological & Economic Value & Wide Applications
In the kitchen garden, the cos lettuce nests the crisp hearts through the cool season. The leaves serve the salads and the sandwiches for the ages, the blanched hearts are the classic of the table, and the plant grows quickly in the cool season. It does well in the rich, moist, well-drained, sunny ground. Crisp, upright and fast.
To grow the Cos Lettuce from seed, sow the seeds over the fine, damp surface of the seed tray, then press them in without covering, keep the tray in the bright, cool spot and mist gently, and the seedlings show themselves within a week or two.
