Ash

              The most distinctive feature of the ash is its leaves which are pinnately compound (see tree identification section); when talking about compound leaves, the word leaflet is used; the whole leaf is made up of several of these in a certain order. When the leaves actually fall off the tree in the autumn, we would normally refer to these leaflets as the leaves.

              The compound leaf is made of several of these leaflets in a certain order. It is difficult to tell the ash in the winter, but it does have fairly unique bark with grains tending to follow a pattern upwards along the bark. Also, the twigs silhouette long with a slight curve.

              In the spring, the ash is one of the last trees to go into foliage, and is one of the first to shed its leaves in the autumn, so you have to enjoy its summer glory while it lasts. Its leaves are particularly striking in the autumn when they begin to go brown and, perhaps because of the arrangement of its leaves in a series of lines, there is an optical distortion effect which causes pretty patterns.
