I bought a couple of Quercifolias Katherine - the autumn colour is gorgeous.
I think it's difficult to grow them well if your soil is very dry, until they're well established. No amount of manual watering really makes up for it. Perhaps a load of manure into the planting hole and a ton of mulch to help retain any moisture?
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
I would leave the dead flowers on. They act as a insulater during the winter. Is your plant in partial shade, the reason why i'm asking. There a woodland plant and do best in that type of enviroment. Always keep the soil moist around them also. Letting it dry out can hinder flower development.

Yep, that's the plan for the ones I'm planting this autumn.
And deep shade in summer. 
Good luck with them Katherine
