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.
