Although grey skies and cooler than normal, overcast days seem more prevalent than usual this summer, thankfully, there are still plenty of bright spots of colour to bring a bit of cheer as our gardens reach their peak of lushness and richness of bloom. On a wander through the garden, or when I am weeding or deadheading borders to keep displays looking fresh and vibrant, few things are more satisfying than coming across a perfect pairing or combination of plants.
