Climbing hydrangeas are great plants for shade. Hydrangea anomala ‘Petiolaris’ is a good deciduous variety with heart-shaped leaves.
It’s self-clinging so it requires no support, and it bears white lace cap flowers in summer. The foliage goes a golden yellow colour in autumn too.
Pileostegia viburnoides is another climbing hydrangea for shade that self-clings.
It has narrow, leathery leaves in a dark green colour, and dainty white flowers in summer. It will grow more or less anywhere.
