What's This?

A customer didn't want this plant. She has no idea what it is neither do I so rescued it and put it in a small plastic jar before a decision on its fate is made

Hate throwing away anything that has potential but flummoxed on this one. Looks like phlox but isn't. It appears to be a woody shrub that has been cut down to the ground by a previous gardener.

Any IDs gratefully appreciated!

 

Thanks for the reply. The pic isn't great bUt the texture of the leaves feels delicate and deciduous
