(Wasabia japonica) Variety \'Misuma\' Chances are, the wasabi you\'ve never had real wasabi but rather a combination of mustard, horseradish, and food coloring. Native to Japan, it is grown for its unique, enlarged stem or rhizome. Wasabi prefers shade and cool temperatures, so is well suited to the Pacific NW. The highest grade of wasabi is grown in moving water but it does just fine in soil and in containers. Wasabi grows best in summer shade on soils high in organic matter, well watered with good drainage. When planting wasabi, the crown should remain above the soil surface. Temperatures below 27° F. will kill the top growth and perhaps the whole plant so winter protection is advisable. Its ideal range is between 40 and 70 degrees. Slugs love it, so slug control may be necessary. Instructions are included with each plant! 4\" pot.
