Hydrangea arborescens (Wild hydrangea)
The wild-type Hydrangea arborescens is not only be a beautiful and sculptural specimen, but highly valuable for wildlife. This deciduous native shrub sports showy, dome-shaped clusters of creamy white flowers and its adaptability to shady, moist woodland conditions. It typically grows 3 to 6 feet tall and just as wide, with spreading stems that may form colonies via underground suckers.
In the wild, its subtle blooms appear in late spring through midsummer and may continue sporadically into late summer. Unlike ornamental hydrangeas bred for sterile, oversized blooms, the native form supports a broader ecological role, offering smaller fertile flowers that are magnets for insects.
Ecologically, Hydrangea arborescens supports a variety of native bees, flies, and beetles, which run across the fertile flowers for nectar and pollen. While most cultivars like ‘Snowball’ have mostly sterile flowers for showy appearance, the straight / wild species provides important resources for pollinators in shaded garden habitats. Its dense root system helps stabilize soils along slopes and streambanks, making it excellent for erosion control in restoration or residential settings.
Though not a significant larval host plant, it is the host species of the vulnerable Hydrangea Sphinx (Darapsa versicolor) moth.
