Last autumn I hacked back an overgrown climbing rose. I had let it run free to see if it would flower more, but it was still heavily overshadowed by my neighbour’s large conifers.
With the rose reduced in size the previously swamped clematis armandii ‘Snowdrift’ has finally started to flower. More of a trickle than a cascade so far.
However, the clematis armandii ‘Appleblossom’, planted at the same time as the ‘Snowdrift’, now cascades down the trellis. The pair make a textbook example of the direct sunlight requirements for most flowering climbers to give a good show.

On the other hand some plants only require the light of dappled shade to produce a display of delicate, drooping jewels.
