Plant dies back and can be treated as a perennial.  Plants attract an assortment of pollinators.  The bumblebee seems to prefer the blossom.   Plants also serve as butterfly nectar sources.  Prune away flower heads after they are spent to avoid seeding.  This will also help in the vigor of the shrub.  Avoid planting in heavy wet soils.
