Wild Oat-grass

Wild Oat

Avena fatua 

Wild oat is random, ­a weed of arable crops
That may or may not be in any field.
It is very obvious, standing high above the barley.
Any farmer would be glad for you to take
As much as possible, and some will always escape.

Found poem from John Crossley the Plant Recorder for Orkney
