Penny is a large firm black English cherry with an excellent flavour.
It is one of a number of new varieties which are very late ripening - mid to late August - making it a good choice for extending the fresh cherry season. It benefits from being trained as a fan on a south or west-facing wall.
Penny is not self-fertile, so it needs a pollination partner and should not be planted as your only cherry tree - but any other self-fertile variety should be compatible. Commercial growers also use Kordia (another black cherry), Regina, Summer Sun, Skeena, Sweetheart, and Sunburst.
