Yorkshire Fog, Tufted Grass, or Meadow Soft Grass are the common names used in Europe. In North America the names are Velvet Grass or Common Velvet Grass. Yorkshire fog or Velvet Grass has velvety grey-green leaves which gives its common names: perhaps in Europe alluding to the fogs of Yorkshire, and in North america to its velvety leaf texture. The shoots are round. The base of the shoots are white with pink stripes or veins - these are used in identification and are known by certain ecologists as 'stripey pyjamas'. The inflorescence is robust and often tinged purple. Yorkshire fog or Velvet Grass produces a large amount of seed and is a rapid coloniser of disturbed ground.
