July 12th – One indicator of an advancing summer I always have mixed feelings about is buddleia. This purple-flowering, profuse shrub, sometimes known as the butterfly bush is great for bugs and bees and lepidoptera of all kinds – but the one issue I have is it’s the shrub of urban decay.
This versatile plant will grow anywhere it can find – gutters, chimneys, soot-filled fissures in brickwork, and once it takes hold it will destroy masonry as it grows. It’s the sign of dereliction in summer, growing old disused rail lines, factory yards and edgelands of all types.
A fascinating, but destructive plant.
