Quercus cerris x suber (Q. x crenata)
A large, semi-evergreen tree of parks, large gardens, woodland and field boundaries. It is fertile and is occasionally self-sown, the progeny exhibiting a range of variation between the parent species. Lowland.
Q. x crenata arose in W. Lucombe`s nursery in Exeter in 1762, less than thirty years after Q. cerris had been introduced there. It has since been widely, if sporadically, planted, but was not recorded formally from the wild until 1964.
The plants normally cultivated are hybrids of garden origin, but the hybrid also occurs naturally with its parents in S. Europe.
