Be warned. Horseradish will take over. I have heard that it should be planted in a bucket so it won't take over your garden. I didn't listen. Now I am fighting to get it out of my lilies. Fresh horseradish is fabulous though.
I am currently trying to grow it in a 6 inch plastic pipe. This is supposed to make it easy to harvest -- just shake it out of the pipe and there is your root. It also keeps it out of your garden.
I considered a negative for this plant due to its invasiveness, but it has redeeming characteristics. The leaves are attractive, also.

Put horseradish where you want it to stay because it is hard to get it all out when you move it. Preparing the root is a good way to clear your sinuses and flood your eyes!

The Armoracia rusticana is a beautiful perennial plant with the ability to feed horseradish lovers as myself. My second year with the plant was delightful because one of the plants sent a stalk shot of white flowers in early summer which lasted for approximately three weeks. My only advice is to not roto-till this plant expecting to eradicate it. The plant will spread which is dependent upon how much and far one tills. Also the plant tends to struggle if transplanted... but don't fret. Give the precious one more time (maybe a year or so) and you'll be impressed with the results.
