Just let it be for now. Severely damaged foliage will eventually drop off and be replaced and you can trim off any topgrowth later when you can confirm it is dead -- IF it is dead :-)

How cold did it get? Typically hydrangeas are unaffected by spring frosts - mine are exposed to them frequently without issue.

Thank you gardengal. I'm not sure of the temperature but it got pretty cold and there was heavy frost and wind overnight.
I'll leave it be for now as you suggested.

I also had my 3rd year Endless Summer seem to bud all over then, spring frost killed all the little buds...nothing has happened since with it. Do you think it is a lost cause now?? It never had a chance to start new buds or needless to say any leaves at all. It's mid-April, nothing at all...

what do you think?

If the stems are green you just have to be patient. Shrubs like these are ones that I wouldn't worry about. You could cut it to stubs and it will grow.

Same problem here with three year endless summers. I've been giving thought of a major trimming as it wasn't shaping well anyway. I'm guessing it will fare well and take on a better shape. I've hear it could re-bloom, but it's not as important.

I pass by a huge hydrangea nearby that a local farmer cuts to stubs in March. By late summer it's flourishing and blooming like crazy, but it has to be 20 years old.

Cadence,

I agree with gardengal...my ES got frost bit just the other night when temps dropped into the lower 30s and my mom told me to just leave the dead leaves and keep the soil moist. She said the leaves would grow back. Thank goodness ES reblooms so i may get to enjoy it at some point this season
