Produces the largest fruit of any Mirabelle or Cherry Plum. The flesh dark red and has a peach-like flavour, and can be eaten fresh although like all mirabelles and cherry plums it is mainly used for cooking.
The fruits are clingstone - the flesh sticks to the stone. However the very large size of the fruits means this is not really an issue for use in the kitchen.
The large fruit size and red-flesh suggests that Ruby may have some relation to the popular Japanese plums.

Ruby grows with a distinctly upright habit, and is quite different in this respect from the more spreading form associated with similar varieties. It is therefore a good choice if space is limited.
As well as the pollination partners mentioned above, Ruby will also cross-pollinate with most early-flowering Plum and Damson varieties.
The fruits ripen towards the end of July in southern England.
