Flowers by the sea, falling down parched walls and in ancient cloisters  Summer flowers in Sicily are bursts of vibrant colour. And during my time in Sicily last summer I saw flowers on balconies, by the sea and the roadside, in a tiny hamlet almost abandoned, in a rambling house garden with views to the sea, in cloisters and wild gardens of an ancient abbey nestled in a forest hundreds of metres above the sea, in pots clustered along streets and on faded stone walls of an interior village.
