The easiest time to identify grasses is when they are in flower, the same as with any plant…
The flowers of grasses may not be as flamboyant as some flora but they are just as varied. The key features used to identify grasses are the arrangement of the flower head, the way in which the leaves attach to the stem and the structure of the stem. If you have a hand lens you can also use the ligule (a small flap of tissue where the bottom of the leaf blade meets the stem) this varies in shape so can be useful in identification.
Four of the most common grasses found in Britain are Cock’s-foot (Dactylis glomerata), crested dog’s-tail (Cynosurus cristatus), Yorkshire fog (Holcus lanatus) and Timothy (Phleum pratense). They are illustrated below with the key features that you need to look for. They are species commonly found in fields, lawns or parks so you should be able to find at least one of them near to your home, so get outdoors and try out your identification skills.
