Eutrema

Eutrema is a genus of flowering plants of the family Brassicaceae, native to the Holarctic. Its best known member is wasabi, Eutrema japonicum. The name comes from the Greek εὐ- (eu-) 'well' et τρῆμα (trêma) 'hole', because of a hole in the septum of the fruit.

It is native to subarctic and subalpine regions of Eurasia and North America and to temperate Asia.
