Prunus domestica. Originated in Ukraine in 1995. Rootstock: St Julien A (semi-vigorous) Ruby produces the largest fruit of all mirabelles. The fruit has an exceptionally sweet taste, with a peach-like flavour and dark red flesh. The tree is unusually upright in the habit in comparison to the wide-spreading bushy habit of other varieties. Self-fertile, but will produce a bigger crop when other plums and mirabelles are present nearby. Pick September. Use: cooking and eating. Priced for: a maiden bush
