Greengage

The Greengage is a cultivar  of the plum.   It was developed in France  from a green-fruited wild plum (Ganerik) originally found in Asia Minor
It is identified by its small, oval shape, smooth-textured flesh, and ranging in colour from green to yellow and is  grown in temperate areas.
They are renowned for their rich, confectionery flavour that causes them to be considered one of the finest dessert plums.

The name Reine Claude, is the name by which they are known in France, and is named in honour of   Claude  (1499-1524),  who became queen consort of King Francis 1 of France. (1494-1547). 

They make excellent jam or purées for pies and puddings.
