I have been reading 'Colour for Adventurous Gardeners' by Christopher Lloyd and delighting in the robust advice, challenging ideas and fabulous photos. My garden is small so I have always restricted strong colours to accents but I think I need to be braver. This photo was taken in a favourite garden on Sunday - it is a tiny, densely planted space with walls of clipped yew. The brightness of the yellow and blue takes your breath away as you enter through a gap in the hedge. I want those colours!
