You may be familiar with the strong flavor of this traditional perennial vegetable.  The root, grated and made into a condiment to help with digetion, it is often served with meat.  We like to make a fire cider with horseradish, garlic, chili, and cider vinegar which is a great salad dressing and general condiment. This plant is quite vigorous and will thrive in a raised bed with garden soil, or grow in heavy clay.  It is important to note that even when harvested annually, it can be difficult to completely remove from a garden.  Therefore, we reccomend growing it in a large pot or pots, which also makes harvesting so much easier.  You can remove part of the root and re-plant the upper portion and it will grow again next year.
