The hydrangea will do better in partial sun. Morning sun, afternoon shade will be fine. I doubt you will see new growth until next spring. It could very well be getting ready to go dormant so you definitely will not see new growth if that is the case. I ordered mine and it was the sorriest 3 twigs I've ever seen in my life last year. Those same three twigs turned into a 2 ft bush this year with much improved growth. Next year should see it hitting its 3 foot mark. Don't give up til next year. If you have no growth next year, then you have a problem. I'd move it to partial sun then wait for next year.
