Plum-cherry hybrid

A plum-cherry hybrid is a hybrid between Chinese or Japanese plum (Prunus salicina and its hybrids) and sweet cherry (Prunus avium). Although it is often called cherry plum, it has no relation to the cherry plum species (Prunus cerasifera). It is also known as plerry (more like a plum) or cherum (more like a cherry).{{Cite web|last=Karp|first=David|date=2012-06-30|title=Market Watch: Plum-cherry hybrids find a sweet spot|url=https://www.latimes.com/style/la-xpm-2012-jun-30-la-fo-marketwatch-online-20120706-story.html|access-date=2021-02-20|website=Los Angeles Times}} Commercial plum-cherry hybrids include 'Nadia',{{Cite web|last=Rullo|first=Joseph|title=Plum × cherry interspecific hybrid tree named 'Nadia'|url=https://patents.google.com/patent/US20090044301P1/|website=US20090044301P1}} CherriYum!, Verry Cherry Plum (cherum hybrids, including 'Sweet Pixie',{{Cite web|last=Zaiger|first=Gary Neil|last2=Gardner|first2=Leith Marie|last3=Zaiger|first3=Grant Gene|title=Interspecific tree named ‘Sweet Pixie’|url=https://patents.google.com/patent/USPP23211P3|access-date=2021-02-20|website=USPP23211P3}} 'Sweet Pixie 5',{{Cite web|last=Zaiger|first=Gary Neil|last2=Gardner|first2=Leith Marie|last3=Zaiger|first3=Grant Gene|title=Interspecific tree named ‘Sweet Pixie 5’|url=https://patents.google.com/patent/USPP28308P3|access-date=2021-02-20|website=USPP28308P3}} etc.) and Pluerry (complex plerry hybrids{{Cite web|title=Zaiger Interspecifics|url=https://www.davewilson.com/product-information-general/zaiger-interspecifics|access-date=2021-02-20|website=Dave Wilson Nursery}}).
