Ilex × attenuata, the topal holly, is the result of a cross between Ilex cassine (dahoon) and Ilex opaca (American holly). It is a naturally occurring hybrid found in the southeastern United States where the ranges of the parents overlap, but hybrid cultivars have also been created.{{cite web |url=http://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:287561-2 |title=Ilex × attenuata Ashe |author= |date=2017 |website=Plants of the World Online |publisher=Board of Trustees of the Royal Botanic Gardens, Kew |access-date=5 December 2020 }} The best known cultivars are 'Fosteri', Foster holly, which does not require males to set fruit, and 'Savannah', with very showy red fruit.{{cite web |url=http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=q190 |title=Ilex × attenuata 'Fosteri' |author= |date= |website=Plant Finder |publisher=Missouri Botanical Garden |access-date=5 December 2020 }}{{cite web |url=http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=c527 |title=Ilex × attenuata 'Savannah' |author= |date= |website=Plant Finder |publisher=Missouri Botanical Garden |access-date=5 December 2020 }}
