Seneca plum


Seneca is a sweet-flavored red / purple European plum, notable for its particularly large fruit size.

Seneca is a useful choice if you are looking for a late-season dessert plum, it ripens in early September. The stone falls cleanly away from the flesh (freestone).

Seneca is a cross between Italian Prune and Prinlew. It was developed at the New York State Agricultural Experiment Station (NYAES), Geneva, USA in the 1940s and eventually released in 1972 - and is arguably the best European plum variety developed by NYAES.
