Q.Hydrangeas
I built my house about a year ago and have been daydreaming of what all I will plant in my yard with NOTHING in it. blank canvas. This year I decided to start working on my gardens as my plans will take years to execute. The first plants I wanted to put in are, my favorite, hydrangeas. So I got up at dawn and watched the sun, checking every hour. The spot I was considering turned out to get much more sun than I had thought. I love mopheads and was thinking of blushing bride, nikko, l.a dreamin, and annebell. However I discovered this area receives sun starting at 8:00 am and isn’t in complete shade until 4:00 pm (Knoxville, Tn).I could have sworn it was more like 2:00 pm in full shade but I checked every hour. So my question is this. Whatever I plant I want it to thrive and be in optimal conditions. So should I stay away from these kinds of hydrangeas? Should I steer more towards limelight and vanilla strawberry? Or does this location get too much sun for them as well? Any insight is appreciated! I hope I gave you enough details to be able to guide me in the right direction.
