Repellent, not only to fleas but to cows as well, fleabane stands alone at the edge of the bog. Overlooked in the floral orgy of summer, only it marks the boundary between wet and damp now. Smoky blue has given way to dark chocolate and dirty chalk. Yellow on yellow has become ochre on black. The low sun turns thousands of fuzzy seed heads into angelic halos. The only witnesses to the muddy probings of a wisp of stripy snipe.
