Common Mallow

Common Mallow is out all over the place at the moment. Malva sylvestris  has a pretty flower but somehow its growth habit detracts from the overall aesthetic effect. It's untidy and straggling, with a tendency to grow in insalubrious spots where it thrusts itself out at you like a cheap tart. 
A bit harsh perhaps, given that it does brighten up the waysides, but one mustn't fawn over every flower with a bit of colour: one must have standards!
