Planting and Care
Does NOT tolerate poorly drained soils or "wet feet" in winter. In Zones 5 and 6 top growth will die back to the ground. Treat this shrub like a perennial and prune back top growth in late winter. Be patient, plants are slow to emerge from dormancy. This cultivar of butterfly bush is reportedly almost sterile, producing few seeds.
Problems
Rot in wet soils
