It is an ongoing problem of gardening that after the first five years of a new planting, serious, annual pruning is needed to keep the more successful specimens to appropriate sizes.
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.
