We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Worth growing because horseradish is easy to make in the quantity you want or need. Store-bought, you only use some, and put it away in the refrigerator only to be tossed out months later. In addition, you don't get any additives and preservatives like you do with commercial brands.
I made fresh horseradish sauce once. I threw some horseradish roots into the blender, along with some vinegar and salt. After pureeing the horseradish, I removed the lid from the blender and stuck my nose down in there. It was so pungent that it almost stopped my heart. Don't try that at home.
No it's not, but a common misconception. Real Japanese wasabi is a different plant. But real wasabi is hard to find and expensive, and so horseradish is frequently faked as wasabi and used instead (green dye added).
Horseradish is the toughest plant in our garden. At one point my wife wanted to get rid of it. She dug it all out but must have missed a root fragment. Next year it was back.
She tried increasing doses of Round-Up. All that did was make it look wilty and a bit brown for a few weeks each time. Near the end of her efforts she was practically pouring straight concentrate on the thing.
She gave up. Horseradish wins. She's back to making her own horseradish condiments, which as snopercod points out out can be extremely powerful.
Horseradish is only indestructible if there is regular rainfall. My horseradish dies pretty quickly if it's not watered regularly in our bone-dry six month Middle Eastern summers. I was surprised because I assumed the fleshy root would give some drought tolerance. Does not seem to be so.
