Different Types of Hydrangea Arborescens and their Pruning Requirements
There are several types of hydrangea arborescens, each with their own pruning requirements. Here are some of the most common ones:
Annabelle Hydrangea
The Annabelle hydrangea is one of the most popular varieties of hydrangea arborescens. It produces large white flower heads that can be up to 12 inches in diameter. This plant blooms on new wood, which means it should be pruned back hard in late winter or early spring. Cut all the stems down to within 6-12 inches of the ground.
Incrediball Hydrangea
The Incrediball hydrangea is a newer variety of hydrangea arborescens that produces larger flowers than the Annabelle. It also has sturdier stems that don't flop as much. This plant should be pruned back hard in late winter or early spring, just like the Annabelle.
Wee White Hydrangea
The Wee White hydrangea is a smaller variety of hydrangea arborescens that only grows to about 2-3 feet tall and wide. It produces small white flower heads that are about 4-5 inches in diameter. This plant blooms on new wood, so it can be pruned back hard in late winter or early spring, just like the Annabelle and Incrediball.
