The best things in life are free. Two pics I took last week- examples of the beautiful associations of colour that can occur when plants run wild.
 In the top image -taken by the kitchen door- the blue/mauve flowers and greenery of Trailing Bellflower (Campanula porscharskyana) scramble into the foliage of a clump of Herb Robert (Geranium robertianum) which has turned from green to bright red as it struggles with the near drought conditions of recent weeks.
 In the bottom image blue and white forms of the Peach-leaved Bellfower (Campanula persicifolia) have seeded freely among the grasses and Ox-eye Daisies in an overgrown section of the allotments. In this country C. persicifolia was introduced as a garden plant but left to its own devices it has reverted to being a meadow plant, one of its natural habitats in continental Europe.
