Several friends, and a couple of professional horticulturists, have told me this shrub has a couple of weeks of flowering glory in spring... and otherwise it's just a big bush. Funny, I never hear them say anything derogatory about Forsythia, Quince, Azaleas, Wisteria or Lady Banks Rose... and they pretty much do the same thing.
A large, irregularly shaped Pearlbush in full bloom is a marvelous sight. And if you are fortunate enough to see this plant in full bloom on a night with a full moon you are in for a great, springtime treat.
