Dr. Michael A. Dirr, the professor of ornamental horticulture who wrote the huge manual of "Manual of Woody Landscape Plants," discovered a vigorous seedling of the Oakleaf Hydrangea on the campus of the University of Georgia where he was teaching in the 1980's, and he propagated it to become a cultivar. He introduced it into commerce with the Georgia Plant Introduction Program. This cultivar is a larger selection that grows 8 to 15 feet high. Its leaves tend to be larger. Its flower clusters are large of about 10 to 14 inches long, that bear mostly outer showy infertile florets, but has some fertile florets in the inside. This is one of the most common cultivars sold.
