Are expecting them to bloom continuously like some roses? Hydrangeas like ES/etc bloom and then take a rest for several weeks (4-6... sometimes more) before they bloom again. Each bloom stays out there for quite a long time though. But in the middle of the summer, many plants take a rest from blooming and restart when temps moderate (like roses for example); remontant hydrangeas will do the same. It is just wait out too hot when the temps are regularly in the 100s.

Thanks for the info. I wasn't sure how they were supposed to bloom. I didn't expect them to bloom like roses, however I was under the impression they would bloom all summer long (endless summer) : ) and since the other two ES are blooming right now I thought something was wrong with the TS.

I guess I need to be patient. Thanks again!

It just might need some time to mature. I suspect this plant is younger than the others as it is a newer variety.
