Castleton plum trees

Castleton is a modern dual-purpose early-season plum. It was developed for the New York commercial plum-growing market, and these qualities also make it a good choice for the backyard orchard.

Castleton can be eaten fresh when fully ripe or used in the kitchen if picked slightly earlier. It is a freestone plum - the stone falls away from the flesh easily.
