A small plum, possibly a type of Shropshire prune crossed with the wild bullace and sloe.

The Westmorland Damson Association say that; "Westmorland damsons grow mainly in and around the Lyth and Winster valleys, south-west of Kendal in the English Lake District. The orchards of the Lyth Valley are unique, surrounding each small farmstead and growing along every hedgerow in the valley.
At some time in April, exactly when depending on the weather, the orchards and hedgerows become snow white with blossom - a wonderful sight to see. The fruit ripens in September and is sold from roadside stalls and in local shops."
