When I moved to this shady neighborhood with towering hardwood trees nearly seven years ago, I was happy to find several species of hydrangeas growing in the garden. Since then, I’ve added even more of these beautiful and easy-to-grow shrubs.
My favorite hydrangea was not planted here, however, it grows wild. Hydrangea radiata, though limited in its native range to the southern Appalachian region, is common in the Upstate and I often see it on my wildflower hikes. In the garden here, it grows on a moist, north-facing slope above the Reedy River.
Called silverleaf by those who prefer common names, this hydrangea has striking foliage as well as pretty flowers. While the upper surface of the leaf is green, the underside is bright white, a tale-tell feature easily seen when ruffled by wind.
In June, creamy-white blooms open at the tips of the shrub’s spreading branches. Clusters are flat-topped, with larger, sterile flowers surrounding a center of fertile flowers that produce pollen and seeds. One of the nicest things about this hydrangea is that it attracts a wide variety of pollinators.
In early spring 2012, I added a (then) new selection of hydrangea to the garden that also blooms in June. Named Incrediball, this Hydrangea arborescens, commonly known as smooth hydrangea, is touted as an improvement over its popular parent, Annabelle, offering thicker, sturdier stems that prevent flopping after rain.
Like others of its species, Incrediball blooms on new wood, so even when killed to the ground during a hard winter, new branches produce summer flowers. It’s also said to be more floriferous than Annabelle, with up to four times more flowers.
This selection, with its bold white blooms that fade to parchment and persist throughout the winter, has become a great favorite. Sadly, it’s also much-loved by voles, but that’s another story.
