Horseradish
Horseradish is a perennial flower originally from Europe, grown for its edible, spicy root. In the landscape, it is grown for its beautiful leaves.
Its large leaves grow on long, upright stems. They are quite attractive, with wavy, undulating edges.
Horseradish makes an excellent specimen plant or backdrop for other perennial flowers. It is very resilient and grows well in the Colorado Springs area if it receives enough moisture.

Performance
Horseradish has grown quite well at the Water Wise Demonstration Garden, both in garden settings and in pots. Its large leaves are a nice contrast to more fine-leaved plants.
Maintenance
Horseradish spreads aggressively through undergrounds stems. To prevent it from spreading, plant it in a buried large plastic tub with the bottom cut out. The sides of the tub will act as a physical barrier for the root system.
Cut off spent flower stalks, if desired.
