A multi stemmed plant (shrub?) with these lovely white spires of 6 pointed star flowers. Any ideas?
It was hidden behind an enthusiastic cotoneaster, and the stems have grown horizontally along the earth towards the front on the border, before finally getting to the light and flowering!
I’ve staked the stems up for now, but not sure a) what it is and b) what to do with it (apart from pruning back the cotoneaster…).
