    Check you local garden centers and ask for a large growing pot in the size you need.
    Also check Ebay, they are often a good source for these items.

    Your average lowest temperature is -10.5 degrees Celsius (13.1 degrees Fahrenheit). Horseradish is hardy to zone 3 or about -40 degrees F. So it looks like you could grow it in a container. I would still cover it with hay or mulch during January at least.

    I would attribute this to a sulfur deficiency. This plant is not really a high feeder, so standard deficiencies aren't as common. Sulfur deficiencies can go largely unnoticed, though.

    The chemical compound, isothiocyanate, is responsible for the "spicy" in this plant. This chemical can only be formed in the presence of sulfur. This can indicate that there is a lack of this in the soil.

    Try fixing this with iron sulfate, or wettable sulfur. That should take care of the issue, going forward.

    They will do well in container. They will also do fine outdoors in that area, and even becoming invasive. If you would like to take some in container it will do just fine, but at some point you may want to plant it outdoors.

    This plant will be fully hardy in your area. No extra care is needed, although, when you harvest you will want to leave some portions of root. This will be next year's crop.

    The problem with the Brassicaceae family is that so many resemble each other. Pinning down an ID will be difficult.

    I would ask your neighbor. Since that is the person that gave them to you, I would suspect that they have an idea as to what they are.

    My best guess is going to be horseradish leaves.
