I think so! Congratulations!!!

Hi Danajean,
It looks like a Hydrangea to me. My neigbor has one that looks exactly like this. It's gets bigger every year; however it never has any blooms. We are not sure if it's because it's right under the springler head and gets too much water or if it's because it's under a huge pine tree and gets too much shade.

do you see any blooms on yours? Good luck with it and post pics once it blooms!

Since hydrangeas are suckering shrubs, producing multiple stems from the root crown, the ones in the ground look exactly as they should. It is very unusual for a hydrangea to have a single woody trunk :-) I'd guess only because they are still very young plants and in a container - established in the ground they will eventually look just like the others.

Mophead hydrangeas in your climate will require winter protection to ensure the viability of latent flower buds. The vast majority of these bloom on the previous season's growth - pruning and cold damage can impair or eliminate flowering. I'd not expect much in the way of flowering from those in the ground - first, because they have been pruned badly and second because they were likely exposed to winter cold that would have killed off flower buds.
