Answer: Since you've only recently planted your Endless Summer Hydrangea I think it is safe to say it is going through a little transplant stress and is withholding flowers so it can concentrate on establishing its root system. I expect it will bloom again a little later this summer. Endless Summer produces flowers on both old and new wood, so even if it freezes down to the ground each winter, it should produce flowers on the new growth. Aside from needing at least 4 hours of morning sunshine, adequate water and occasional pruning, there's really nothing else that needs to be done to assure flowers each year. Give your plant a few more weeks to establish and I'm sure it will bloom for you. Enjoy!
