Flowering Seasons: Many hydrangea cultivars produce flowers during the spring, summer, and fall.
Varietals: Bigleaf, panicle, smooth, mountain, and oakleaf hydrangeas each have distinct features and growth requirements.

Why Grow in a Container?

Container gardening offers numerous benefits, especially for those with limited space or in colder climates. Here’s why growing hydrangeas in containers might be the perfect choice for you:

Space-Saving: Containers allow you to grow hydrangeas in small spaces such as balconies or patios.
