Where can I buy Wasabi (Wasabia) seeds or young plants online?

• Answer:

  The Wasabi rhizome can take 2-3 years to mature to a length of half a foot or more and a 1 inch diameter. When harvested, side roots are pulled off and used to start new plants, which may grow to 2 feet high and wide. The best Wasabi is grown in gravel by diverting cold water mountain streams through the gravel bars. Real Wasabi sells for over $100 per ounce processed into a paste. You do not get real Wasabi in restaurants, they simply can't afford to provide it, and there isn't enough of it to supply the high end restaurants and bars wanting it. Restaurants and most Sushi Bars provide fake Wasabi consisting of Horse Radish Paste, Vinegar, Dried Hot Mustard and food coloring. Even the ‘Wasabi Paste’ found in specialty shops is usually imitation Wasabi. If you want to experiment around with some root, it will be expensive and you will have to wait a couple of years for your first harvest, but here is the site to purchase Wasabi root straight from Kyoto Japan. http://www.thewagyubeef.com/wasabi.html $50 for 4 oz. root.
