Hi,

Plumcot is the result of the interspecific hybridization of apricot (Prunus armeniaca) and the genetically compatible sand cherry (Prunus pumila spp. besseyi - western sand cherry).  Burbank was one who was successful in forming a "plumcot".  Their bloom periods seem to match up, in the Atlantic northeast.

Asian plums will freely hybridize with US-native plums, open-pollinated, as their chromosomal counts are equivalent.  I think apricot (will they?) and Asian plums will cross.  So, will apricot freely hybridize with native plums, including and/OR specifically sand "cherry" (a plum)?

Thanks,

Steve
