Although a native of mixed forest through much of southern China, Quercus fabri is scarce in cultivation in Europe, only a few young plants being found in the important oak collections. With its large leaves, the overall appearance of the species is similar to that of Q. mongolica subsp. crispula or Q. dentata. At present it is too early to assess its potential in cultivation. In October 2005 a specimen at the Hillier Gardens (from Rippin 167, collected in Yunnan in 1999) had been badly insect-damaged and seemed to be struggling, though by 2008 it had reached 3.5 m. The species apparently fares better in continental Europe, young trees from Eike Jablonski’s 1999 collection from Yunnan thriving throughout Germany and up to 1.5 m tall in 2006 (E. Jablonski, pers. comm. 2006). There are larger specimens in the United States, one observed at Starhill Forest Arboretum being 7–8 m tall in 2006. The tree has nice glossy leaves that are paler below. Guy Sternberg (pers. comm. 2006) says that it has never shown signs of winter damage.
