Ynghylch

Wych elm is rarely found as a tree, but is more common as a hedgerow shrub. This is a likely result of the ravaging effects of a recent wave of Dutch elm disease which has affected all of the UK's elms, killing many mature trees and preventing new trees from growing. Mature wych elms can be found in woods, often alongside streams and in upland areas. It is one of the few elms to spread mainly by seed, instead of propagating clones from root suckers.

What to look for

Elms can be recognised by their asymmetrical, oval leaves that are toothed around the edges and have very short stalks. Wych elm leaves are larger than those of other elms, taper to a sudden point at the tip, and are hairy on both sides. The leaf tips can sometimes resemble a 'W', with sharp toothed edges either side of the longer, tapering point. Wych elms produce winged fruit, with the thin wings curving inwards to form a circle or oval around the seed in the centre. The seed is green at first but soon turns reddish-brown.

Where to find

Widespread but scattered distribution, most common in the north and west.

The name 'wych' does not refer to a link to witches or magic, but actually means 'pliant' or 'supple' in old English, relating to the wych elm's properties as a wood for making Welsh bows.
