Off the top of my head Little Lime, Little Lamb, Bobo, Bombshell and I have had success with Sike's Dwarf in sun from noon till almost sunset.

thanks i read some old post on starlight and together

If you want colored mopheads, I see the 'Let's Dance' series (Starlight/Moonlight/Big Easy) doing well. Someone around the corner from me has one in dawn-dusk sunlight and it hasn't missed a beat.

As far as panicle hydrangea go, you can now find 'Bombshell' at some Lowe's. It looked like they got a shipment in this week.
