Real Wasabi. Wasabi growing in gravel beds flooded with spring water Wasabi prefers cool, shady conditions and will sometimes thrive if left undisturbed in misty mountain stream beds.
It generally requires a climate with an air temperature between 8°C (46°F) and 20 °C (70°F), and prefers high humidity in summer. Since it is quite intolerant of direct sunlight, wasabi is typically grown under shade cloth or beneath a natural forest canopy. Wasabia japonica grows in northern Japan, parts of China, Taiwan, Korea and New Zealand.
