This popular plant, the Penny Mac Hydrangea shrub (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.
Mini penny hydrangeas tend to have blue flowers in acidic soils and pink flowers in more alkaline soils depending on the soil pH. The dark green leaves will stay on the shrub until the first frost and contrast the blooming mophead flowers nicely.
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 on this repeat bloomer and it is seriously gorgeous!
Penny Mac Hydrangea Planting
This blue hydrangea cultivar thrives in rich, well-drained soils and prefers partial shade unless grown in consistently moist soil. A slow release fertilizer at the top of the root ball annually will encourage new growth.
This acid loving plant is the perfect shrub for dappled shade in your backyard. The flower color can be changed by adding pH-changing substances to the soil. To make the large flowers have blue blooms add aluminum sulfate to their soil. To see more pink flower buds add dolomite lime the soil.
Creates a gorgeous pink/blue display in any yard or landscape.
Penny Mac Hydrangea Pruning
This deciduous shrub generally does not need much pruning. Hydrangea blooms on new wood so pruning dead wood from the previous year is okay. You can also prune crossed branches or to maintain desired size and shape.
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. Water thoroughly the first year of planting to establish before winter.
Grow across the United States in USDA growing zones 5-9. The mophead hydrangea plant is extremely cold hardy and is pest and disease resistant.
