Common name: Japanese horseradish, wasabi
Wasabia japonica is a perennial plant native to Japan whose roots are used to make a pungent condiment. Most wasabi sold is not the real thing because it is difficult to grow. When young, its heart-shaped green leaves are edible and have a spicy taste. The flowers, called hana wasabi, are also edible.
Our plant is found edging the Japanese Bed.
