One of the largest plums we grow, Grenville Plums can get up to 5 to 6 cm (2 1/4") in size. These orangey-reddish-coloured plums are sweet, juicy and mildly flavoured. The Grenville Plum has clingstone flesh and is excellent to eat fresh off the tree. The plums ripen around early September and can be a heavy producer in some years. Introduced in 1941 by the Horticultural Division of the Central Experimental Farm in Ottawa, Ontario. Growers Note: It is highly recommended that you purchase a Canada Plum or an American Plum to pollinate our Hybrid plums, as they are self-sterile. Plum trees like fertile, well-drained soil. They should be planted at least 3-4m (12-15 feet) apart, and fruit can be expected around 4 to 6 years of age. Hardiness Zone: 3 Height at Maturity: 3 meters (10 feet) Spread: 4 meters (14 feet) Soil Preference: Well drained Light: Full sun Pollination: Self-sterile (Needs a pollinator; a Canada Plum or an American Plum) Latin Name: Prunus ‘Grenville'
