  Origin & History

‘Tatsoi’ - open-pollinated mustard green from China, cultivated since the 6th century. Already during the Song Dynasty (960-1279 AD) it was mentioned in old Chinese sources as “Tah Tsai” or “Wu Jing Cai.” Later the variety spread to Korea and Japan, where it also became part of regional cuisine. Over centuries, this local landrace was further developed through selection and natural adaptation, distinguished by its robustness and adaptability.

In Asia, ‘Tatsoi’ is traditionally grown in autumn and winter. This fast-growing vegetable, used for centuries, has proven itself as a reliable crop over generations. Characteristic are its spoon-shaped, dark green leaves with white veins, growing in a dense rosette – a form that clearly sets it apart from other cabbages. With its smooth, creamy leaf texture and distinctive flavor, it is considered a historical rarity and a true enrichment in the varietal garden. Even today, ‘Tatsoi’ is cultivated by enthusiasts and seed initiatives, symbolizing the value of freely accessible, traditional crop plants.
