I have several pieces of horseradish that have been rooted and have the tops growing and they are ready to go in the ground. The question is about how much sun they need. Obviously it is better for my horseradish if I can stick it in a bed of ivy and behind some shrubs so the landscapers don't pull it out (again) thinking it is a weed.

Give it full sun to partial shade. By the way, you can also grow this in containers, which should keep the landscapers at bay. This article should help as well: https://www.gardeningknowhow.com/edible/herbs/horseradish/growing-horseradish-how-to-grow-horseradish.htm
