On Growing Horseradish

I treated myself to a dinner out on Sunday. A local place does prime rib on that night, and they do an excellent job with it. I asked for extra horseradish and got to wondering if that plant would grow here in Florida; everything else does. One of my dinner companions mentioned that he grows it in Toronto, and while he couldn't say if it would grow here, he was able to give me a heads up that once you start it is very hard to get rid of it. That point was reinforced by the following paragraph from a web site i found on Google, Eagle Heights Community Garden.

It is possible to dig out a patch of established horseradish, and at least one person has actually succeeded in doing that. It can take a couple years before it is all gone. There is a type of caterpillar that can be introduced to remove an entire horseradish patch in a matter of days. This particular caterpillar is yellow, very large, and runs on gasoline. It should only be used as a weapon of last resort, because the treads may crush your other vegetables or those of your gardening neighbors.
