Grand Duke (syn. Grossherzog's Pflaume & Grand-Due) is a variety of plum, one of the so-called European plums.[2][3][4] It is one of the many valuable plums produced by 'Thomas Rivers' of Sawbridgeworth, England. The Royal Horticultural Society awarded it a First Class Certificate in 1880. The fruit has a fairly firm, rather dry flesh with a slightly tart to slightly sweet flavor. It can tolerate USDA hardiness zones 5b, 5a, 6b, 6a, 7b, and 7a.[5]
