William P.J. McCarthy™William P. J. McCarthy is an extremely hardy and disease resistant rose bred by Brad Jalbert and named for his mentor. He is easy to spot in the garden because of his massive waves of pink blooms early in the summer that repeat throughout the season. A favorite for colder zones, Williams 4 blooms produce a bright pop against his shiny foliage. This pretty pink Shrub averages 4 x 3 and is a consistent spot of cheer in the garden year after year.
