Tatsoi ( Brassica rapa convar. Narinosa as a cultivated plant family Brassica rapa subsp. Narinosa , Syn. Brassica narinosa or Brassica campestris subsp. Chinensis var. Rosularis ) is a close relative of the Pak Choi , the Chinese cabbage and kai lans as well as the turnip from the Genus Cabbage ( Brassica ). Because of the rosette-like arrangement of the leaves, it has also been given the name Rosetten-Pak-Choi or Rosetten-Bok-Choi . In German it is also called leaf mustard because of its fine mustard note .

description

Tatsoi is a biennial herbaceous plant . A tap root is formed. The foliage leaves are densely arranged in a basal rosette of leaves about 20 centimeters high . The spoon-shaped leaf blade is dark green and ribbed white. The four-petalled yellow flowers are about 1.5 cm in diameter. In the second year, an inflorescence up to 1 meter high develops . The oil from the seeds can be toxic in some subspecies, as it can be rich in erucic acid . Modern cultivars, however, are usually free of it.

Origin and cultivation

Tatsoi ( Chinese  塌菜 , Pinyin tācài , Jyutping TAAP 3 coi 3 , academic usually 塌棵菜 , tākēcài , Jyutping TAAP 3 gwo 6 coi 3 , regional also 烏塌菜  /  乌塌菜 , wūtācài , Jyutping wu 1 TAAP 3 coi 3 ) was originally cultivated as an annual from the warm temperate regions of China to the tropics . Tatsoi also grows in regions with cold seasons at temperatures down to −10 degrees . Due to its cold tolerance, Tatsoi is also suitable for cultivation in winter in unheated greenhouses . The plant needs a sunny or partially shaded location protected from the wind and loose soil. Harvest time in China's temperate zones is usually January and February, while flowering time is March. If grown in a greenhouse, the plant can also be harvested all year round. If the sowing time for greenhouse cultivation is between April and August, harvesting can take place between August and October. The harvest time is usually between 40 and 50 days. With so-called small Tatsoi ( English Dwarf tatsoi ) it takes about 20-25 days until the vegetables are ready for harvest .

Importance in nutrition

Tatsoi can be fried briefly in oil (sautéed) or boiled in water as a vegetable dish. It can also be used as an ingredient in soups or raw in salads . It is therefore often a component of salad mixes .
