Please identify bush with magenta flowers
This may be an extremely common and well-known plant, but this old guy doesn't know what it is, and wants to get another. The bush is more than thirteen years old, about 6 feet high and 6 feet wide. Bush growth pattern, with probably 50 or more stems coming up out of the ground. Very fragrant spring flowers are popular with butter flies and bees, but seldom see hummingbirds working it.
