Like it or not the rubbish damp summer is good for the garden.
Rhododendron will look amazing again next spring with plenty of water around for them to develop their flower buds.
Hydrangeas have also benefited from the inclement season. Hot dry spells cause the soft fleshy foliage to wilt with even the flowers drooping on hot days, if you cannot give them an area of dappled shade or ample irrigation.
We have Hydrangea in flower from deep blue, light blue, green, purple, white and almost pink, if you allow white tinged pink flowers as pink?
