Q.Strange blooming on hydrangea
I have 3 endless summer Hydrangea shrubs. They’ve always bloomed fairly well. This year,I have blooms deep in the shrub,I’m assuming from old wood,while it looks like blooms on new wood are now taller and blooming.is this normal? This first picture shows what I mean the best.

Yes, this can be completely normal. I would recommend cutting off those older blooms (those tucked away and fading) as they die off. This will leave the healhty ones to keep going, and even promote new flowers.
These are a type of mophead hydrangea, and are well suited for your area, and will sometimes need pruning anyway, if they get to out of control. This article will help you to know when to prune different types, but you will be concerned with bigleaf mopheads: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/prune-hydrangea-bushes-hydrangea-pruning-instructions.htm
