Interesting Facts

This hydrangea has a beautiful moth named after it. It’s called a hydrangea sphinx because the caterpillars feed on plants in the hydrangea family. The adult moths are important pollinators of flowers including some species of orchid. They are strong fliers that can be seen hovering like hummingbirds in flight while feeding on nectar.
