Hygeia farm in Foster, Rhode Island at the turn of the 20th century.

[1] The Rhode Island Greening was one of the most popular apples grown in New York in the 19th century.

[2] It is tender, crisp, juicy, and quite tart, and similar to the 'Granny Smith'.

[3] The fruit is large, uniformly round in shape, and flattened on the ends, with a dark, waxy, green skin that turns a greenish-yellow when fully ripe.

It ripens from September to October, keeping well into February or longer.
