History: Greengage plums are a European variety that originated in Iran, although it is unclear exactly how old they are. They were introduced to England via France in 1724 by Sir William Gage, after whom they were named in English when the French labels were supposedly lost in transit. These sweet plums were later brought to North American colonies where they were grown by prominent figures such as George Washington and Thomas Jefferson. Although they have since fallen out of favour in North America, they are still quite popular in western Europe and occasionally referenced in pop culture. Greengage plums are the namesake of The Greengage Summer, a 1958 novel and subsequent 1961 film, and are mentioned in a Monty Python sketch.
Why We Grow It: It is a shame this plum's popularity declined in North America since it is considered a high-quality dessert fruit, possibly even the best dessert plum. Their bright green flesh is incredibly sweet and can also be used for cooking and preserving. Greengage plum trees tend to have a compact growth habit, great for anyone without a lot of space.
