Orange Pippin is a website providing information on the different cultivars of apple, cherry and plums. It was established around 2005 by Richard Borrie, a database programmer who lives in England. Currently, it carries a listing of over 2000 apple orchards and 600 apple cultivars, and it is regarded as the most comprehensive resource for apple cultivars and orchards.
Orange Pippin is named after England's most famous apple variety, the Cox's Orange Pippin which according to them, is widely regarded as the finest of all dessert apples.
