This is true wasabi. Native to the mountain streams of Japan this variety is one of the main wasabi production cultivars. Can be grown both in aquaculture and in soil. Needs good moisture and shade. In soil it will do best if watered regularly. Commercial growers will mist daily or plant with roots close to running water. Space plants 1 to 2 feet apart. Do not let it dry out. The root is harvested after 2 years of growth, then ground into a paste to make the traditional condiment. These plants already have developed roots! However the entire plant is edible, and the leaves and flowers are a gourmet addition to many dishes. Most of the wasabi sold with sushi today is actually the much harsher and spicier horseradish with coloring. True wasabi is a much more refined flavor with a subtle sweetness.
Hardy to 27°F. Cover if colder. Mine have survived down to 17°F mulched and then resprouted.
