Thank you for reaching out with your question about identifying your hydrangea shrubs and pruning these shrubs to produce the best flowers.

Hydrangeas are one of the most popular blooming woody shrubs in Ohio landscapes. Hydrangeas have become a popular choice for Ohio gardeners due to their ability to attract pollinators, their long blooming period, and their ability to thrive in various soil types and climates. For these shrubs to perform well in the landscape, home gardeners must prune them properly. Different types of hydrangeas require different pruning techniques depending on the time of flowering.

I would suggest that you start your research by using the following links to learn more about the different types of hydrangea shrubs:
