You can buy fresh horseradish in the produce section of most larger supermarkets if you want to grate it yourself. If you want the prepared stuff...it is in the cold section near the cheese, yogurt, etc.
Horseradish is at its best in fall and winter. Like so many other root vegetables, however, it stores well and is often available in decent shape well into spring. Jerusalem artichokes/sunchokes are brown nubs, that look a bit like small pieces of fresh ginger.
