Container combination ideas
As they will quickly fill a container, they’re typically planted alone. That said, anything that has the spill factor can be added.

Display Tip
Hydrangeas are amazing in containers or massed as a hedge. Try them in pairs of large pots flanking a door, gate or path, or grouped against a fence where the form can be best silhouetted.

Key features
Many improvements to the species have been made, most notably that this variety (like all the Seaside Serenade collection) reblooms, even in warmer, more humid zones. It is a tetraploid and is distinguished by stronger, thicker stems, a reliably compact habit and thicker leaves that better resist heat, humidity and wind.
