Penny Mac Hydrangea is a great plant that has
the superior ability to bloom on both old and new wood. It is known for
quantity of blooms, fast growth rate, and disease resistance. It was first
introduced by Mrs. Penny McHenry of Atlanta, Georgia, founder of the
American Hydrangea Society and famous in Atlanta gardening circles.
She received the original plant as a gift in 1975 and in 2000 gave
specimens to Dr. Michael A. Dirr at the University of Georgia, Dept.
of Horticulture. Through Dirr’s research, it was found to be an
exciting cultivar for the home or landscape gardener. Does not like
full sun in southern climates.
