On this page, we discuss hybrids of Quercus castanea that have arisen in gardens. For a full discussion of the species, see the Quercus castanea entry.

Several Quercus castanea hybrids are recorded in gardens: with Q. crassipes at Arboretum des Pouyouleix from seed collected in Puebla in 2009, planted in 2010 and 4 m × 12 cm in 2021 (B. Chassé, pers. comm.); with Q. laurina at Hackfalls Arboretum, a plant Bob Berry originally determined to be Q. gentryi (Hackfalls Arboretum 2023); with Q. eduardi and with Q. sapotifolia at Chevithorne Barton, both introduced by Allen Coombes, the first from Zacatecas in 1995 and the second from Veracruz in 1996. Quercus castanea × eduardi grew quite vigorously but was regularly affected by frost damage; Q. castanea × sapotifolia displayed wonderful autumn colours but was cut back to the ground by a late spring frost after reaching 4 m (Heathcoat Amory 2009).
