Convoy is a Canadian cherry plum released by Boughen Nurseries in Manitoba in 1941. It combines western sand cherry hardiness with Japanese plum fruit quality and has an upright, rounded habit.
Red skinned fruit with yellow flesh ripens in mid summer. Convoy is sweeter, juicier, and less tart than many cherry plum hybrids, making it useful for fresh eating as well as preserves, baking, and canning.
Cold Hardiness Zone: 2
Mature Size: 6 to 8 ft tall

Convoy needs pollen from another cherry plum. Sapa and Sapalta have worked well as donors when flowering overlaps; Manor had a fair result. Opata performed poorly as a donor for Convoy. Western sandcherry may provide pollen if its often later bloom overlaps. American wild plum may help if its often earlier bloom overlaps; neither is guaranteed for this cultivar.

Years, parentage and introducers are as the nursery has long listed them, and have not all been checked against breeders' records.
Accounts of Compass differ, and its skin colour remains uncertain.
New Oka's colour and size are as Prairie growers describe this group of cherry plums.
Convoy's size is one retailer's figure.
