Leaf celery

Leaf celery (Apium graveolens var. secalinum Alef.),[1][2][3] also called Chinese celery or Nan Ling celery, is a variety of celery cultivated in East Asian countries for its edible, flavorful stalks and leaves.[4]

The stems are thinner than those of Western celery, and curved into round, hollow stalks.

Also, unlike with Western celery, the leaves are used as well as the stalks.[5]
