A plant related to the lettuce. If sown in early spring, either in hot-bed or in the open ground, in April, it will be ready in May. Set out at distances of fifteen inches apart. It is mostly used towards fall, however, and when wanted at that time, should be sown in June or July, and set out in August and September; nothing further is done after planting but hoeing to keep down the weeds, until it attains its full growth, which is from twelve to eighteen inches in diameter. It is then "blanched," either by gathering up the leaves and tying them by their tops in a conical form, or by placing a slate, or flat stone, on the plant to exclude the light and effect the blanching. It is used as a salad. The varieties are the Moss Curled and Plain-leaved Batavian.
