I planted this in a cement planter that is part of the house. I could not get a thing to grow in it, not bulbs, tomatoes, even our native weeds would not survive this horror of a planter even after I dug out and replaced what I believed to be the same 50 year old dirt. Finally in the grocery store I saw some budding horseradish took 2 tubers home to give them a try...I'm going to get 3 more as soon as I find them they LUV the planter, been there a year now and they are florishing and they are so attractive with there bright green lush leaves...thank goodness the planter is no longer an eye sore from the road...Bonus they require NO care...and NOTHING chews on them (dancing)

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.

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 recommendation is to not rototill 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.

Fresh horseradish is the best! Very easy to grow, out-competes almost all other plants.
