Stanley Plum Tree Overview
The Stanley Plum tree is a European freestone plum variety that produces delicious deep violet blue colored plums. Moreover, the fruit is very sweet and can sun-dry into tasty prunes. This cold hardy plum tends to ripen in September and is a freestone variety. Not only is the fruit good for eating fresh, but also for canning and drying because of its firm texture as well as juicy and sweet flavor. Originated in Geneva, NY by Richard Wellington from New York State Agricultural Experimental Station. Introduced in 1926. It was a cross between Agen and Grand Duke. It ripens one week before Italian Prune.
Just like any other plum tree, the Stanley plum tree grows best in full sun with well-drained soil which has average moisture and is loamy. Grows well in hardiness zones 4 to 9. If you would like more information on how to plant and grow this tree, see our guide or the USDA website.
