The big "secret" is moisture for hydrangeas. get PLENTY of organic matter into the aoil at planting time. Get it deep too....a sort of reservoir....and mulch well annually. Water regularly for best flowers. hydrangeas will cope with sun under those conditions.
Charlie, can you plant something on the sunny side to create some dappled shade for your hydrangea? A miscanthus grass will do the job. PH test your soil. if its alkaline maybe go for a dark red hydrangea.
We have discussed the latest hydrangeas here and there are now some fantastic new varieties with dark foliage.
and,,yes, you can plant now
