I have Hydrangea anomala ssp anomala 'Winter Surprise'
Reliably evergreen, hardy, goes reddish in winter but not yet clinging on after 3 years.
I still prefer the basic H. anomala, deciduous but with attractive flowers, dried heads and bark.
I'd not have the parthenocissus, not a long enough season of interest as well as the invasive tendency.
