Lactuca sativa var. angustana
Also called Lettuce, Blue Sow Thistle, Lettuces, Wild Lettuces
Celtuce is a lettuce cultivar grown mainly for its thick edible stem, with the leaves also eaten. It is grown like lettuce: sow in cool weather and harvest the stem when about 30 cm tall.
Celtuce () (Lactuca sativa var. augustana, angustata, or asparagina), also called stem lettuce, celery lettuce, asparagus lettuce, or Chinese lettuce, is a cultivar of lettuce grown primarily for its thick stem or its leaves, which are known as A-choy. It is used as a vegetable. In China, the family is informally called woju (traditional Chinese: 萵苣; simplified Chinese: 莴苣; pinyin: wōjù), which is also the name of a cultivar. It is especially popular in both China and Taiwan, where the stem is interchangeably called wosun (traditional Chinese: 萵筍; simplified Chinese: 莴笋; pinyin: wōsǔn) or qingsun (青筍; 青笋; qīngsǔn).
It can be grown from seed and is sown from April through May in the Northern Hemisphere. The seeds can be planted in a set bed or a temporary nursery bed and then transplanted to the growing site. They should be spread 30 cm apart each way. The young (edible) leaves are ready about 4–5 weeks after planting and the edible stems are ready when about 30 cm tall. They are usually harvested between July and September.
The plant can suffer from aphid attacks.
