The purpose of this cross was to attempt to create a cold hardy citrus tree (which is the nature of a trifoliate), with delicious fruit like those of the sweet orange. However, citranges are generally bitter.

Citrange is used as a rootstock for citrus in Morocco, but does not prevent dry root rot or exocortis disease.[2]

Cultivars

There are several named citrange cultivars,[3] including the 'Carrizo' citrange[4] and the 'Troyer' citrange.[5] Both resulted from a hybrid between the trifoliate orange and the Washington navel orange. There is also a cultivar called 'Rusk' which resulted from a cross between a Ruby orange and a trifoliate orange.[6][7]
