This popular plant, the Penny Mac Hydrangea (hydrangea macrophylla penny mac), is very low maintenance. Yet it provides a prolific display of beautiful mophead flowers continuously throughout the summer – perfect for the time – pressed planter!
One of the best varieties of the newer cultivars of the popular garden hydrangea, the Penny Mac was awarded a Louisiana Super Plant selection for spring 2012. It was aptly named after Penny McHenry from Atlanta Georgia, who is the founder of the American Hydrangea Society in 1994. She received the original plant as a gift and it has been cloned ever since in her honor.
Its blooms tend to be blue in acid soils and pink in more alkaline soils. This hydrangea cultivar thrives in rich, well-drained soils and prefers partial shade unless grown in consistently moist soil. For best results, begin soil treatments well before the Penny Mac Hydrangea flowers in late autumn or early spring. We have seen color mixtures of pink, blue, and purple and it is seriously gorgeous!
This acid loving plant is the perfect shrub for dappled shade. The flower color can be changed by adding pH-changing substances to the soil. To make the large flowers more blue add aluminum sulfate to their soil. To see more pink flower buds add lime the soil.
This deciduous shrub generally does not need much pruning. It will stay small and compact if planted in a small space. It can grow up to 4-6 feet tall and wide with ample room to establish its root system.
Creates a gorgeous pink/blue display in any yard or landscape.
