Wild Bergamot (Monarda fistulosa) is a structural plant with pink blooms in summer. They prefer mesic to dry soil in sun to part sun where they grow up to 4 feet tall. They are a good choice for slopes and banks. Companion plants include Little Bluestem (Schizachyrium scoparium) and Rough Blazing Star (Liatris aspera).
Powdery mildew can be a significant problem in areas with poor air-circulation.
