New plants help fuel the growth of the green industry but nursery professionals must balance new plants with the public’s, often slow, acceptance of the unknown. Entirely new genera often need a longer learning curve before the public accepts them. The public accepts familiar genera, such as Quercus, more readily even when the species are novel to them. The present paper presents some considerations on the performance, propagation, and growing requirements of several Asian evergreen oaks such as have been observed at the JC Raulston Arboretum in North Carolina (U.S.A.).
