It is a thick, hollow, grooved and elongated stem that consists of cylindrical leaves, with a deep groove running lengthwise, from which numerous leaves sprout that look similar to parsley. If left to grow naturally, the leaves acquire a colour that ranges from yellowish green to dark green. If they come from cultivation, they are usually bleached during the final stages of growth. To do this, the plant is covered so that only the leaves receive light. In this case, the leaves are light green. The leaves have a very intense, pungent, slightly bitter and pleasant flavour. The flavour of the stem is milder and has a certain aniseed taste and a crunchy texture. Blanching, in addition to removing the green colour, also significantly reduces the bitter taste.
