I don't know what this plant is but it definitely is not a Hydrangea….but….here are my hydrangeas in our caravan garden.
Here is my tag, using masks made with post-it notes…..
….Hydrangea bushes stamped with Adirondak Caramel, the background and the H stamped with Potting soil archival. I added little Hydrangea flowers with sparkle of stickles at their centres - I know the little flowers don't fall off so I hope you like this little diversion!
Thanks for looking, Chris
