Citrus sudachi

a.k.a. Sudachi ichandrin

An uncommon citrus similar in size to a very large calamondin or small tangerine. Fruits ripen to orange but are often used when green. The fruits are very acidic, but with excellent flavor.

Seed Availability

Seeds are not available for the Sudachi. Please visit our seed store to view current selections.


Medium sized tree to 15-25ft. It is believed to be a hybrid between C. ichangensis and C. reticulata, but shows typical species-like propagation by seeds. The fruits are best known from the Tokushima prefecture of Japan, where the vast majority of supply is grown. Fruits generally ripen in the Fall, a bit earlier than many of the more common citrus fruits. The fruits grow to 1-1.5 ounces. In Japan, the fruit is prized alongside its cousin, the yuzu.


Trees are hardy to some frost and generally show hardiness along the same lines as the yuzu.

Growing Environment

Grow in full sun. Water regularly during warmer months, less so during the cold season. Fertilize like regular citrus.


Grafting is common, but the sudachi can also be propagated by seeds. The seeds are very slow to sprout when dried.


Fruits are quite acidic but have a wonderful flavor reminiscent of a lemon. The fruits can be eaten fresh but are also used in flavoring beverages and desserts. The fruit is also the symbol of the Tokushima prefecture in Japan. Fruits are often served in single slices, accompanying traditional Japanese dishes such as udon, soba, and fish.
