🍈STANLEY PLUM TREE AND ITS SWEET AND INTENSE FRUITS
Stanley plum tree (Prunus domestica L. ‘Stanley’) is one of the most common and liked varieties of European plum tree. It is known for its high productivity, its sweet fruits and its versatility in cooking. The Stanley variety is a perfect choice for both fresh consumption and drying.
It is not an ancient variety:
🌿 It was selected in 1913 in the United States, thanks to Richard Wellington’s studies, an agronomist at the Experimental Station of Geneva, New York.
📜 This type of prune is the result of a crossbreed of traditional European plum trees, and it has spread quickly in Europe and the entire world because of its resistance and the quality of its fruits.
🌍 Today it grows widely in Italy, France, Spain and the Balkans, especially for its use in the production of dried plums.
We included this tree in our orchard to compare it with its hardier relative and to evaluate its resistance in biological farming. In addition, its fruits are widely appreciated in our plum jam, which is a timeless classic. We also use the Stanley plums in our Amaretto-flavoured plums in syrup.

We launched the e-museum of ancient fruits thanks to a social farming project of the Marche region. The translation is by komalingua
This project enabled five young people with cognitive impairments, aged 20 to 25, to work on the farm. They were selected by psychologists and Anffas social workers, supported by the professional educator Il Faro and supervised by UniMc researchers. Coldiretti Marche handled communication and distribution.
This unique and challenging project led to the creation of both a physical and virtual museum of ancient fruits in SiGi’s garden. This is not only a great honor but also a significant commitment that we are willing to continue with everyone’s support.
