White flower

Yorkshire fog, Holcus lanatus. Yorkshire fog is a grass with velvety grey-green leaves and round shoots. 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’. It’s a popular food source with Speckled Wood, Small Skipper and Wall butterflies. Photo: www.ukwildflowers.com
