We have one in our garden, with mixed results from year to year. Its blooms
are white, and it seems to flower in abundance early in the season .
However, in previous years it stops blooming after its first display, with
only an occasional flower showing here and there....How should I care for
this attractive shrub in order for it to bloom throughout the summer. We are
in zone 5, and the shrub is in a semi sunny location. Right now it is in
full bloom, but I fear for a repeat performance. Much obliged ! Ben
