Willingham Gage (Prunus domestica Willingham) arose at Willingham in Cambridgeshire, probably as a seedling of a Green Gage in the 1800s. It is an ease of care, self fertile and excellent cropping variety, much favoured for its superb quality fruits. For these reasons, it has been selected by the Royal Horticultural Society.

The fruit is similar in appearance but larger than that of the Green Gage. The fruit ripens around mid August when the flesh is sweet and juicy to taste.
