Cold-hardy citrus

Cold hardy citrus is a general term describing citrus with increased frost tolerance which may be cultivated far beyond traditional citrus growing regions. Citrus species and citrus hybrids typically described as cold-hardy generally display an ability to withstand wintertime temperatures below Script error: No such module "convert".. Cold-hardy citrus may be generally accepted 'true' species (e.g. Satsuma mandarin, Kumquat) or hybrids (e.g. Citrange) involving various other citrus species. All citrus fruits are technically edible, though some have bitter flavors often regarded as unpleasant, and this variability is also seen in cold-hardy citrus fruits. Those listed as "inedible fresh" or "semi-edible" can (like all citrus) be cooked to make marmalade.

Varieties

Varieties of true citrus considered cold hardy, ordered from most to least hardy:

Name Hardiness Edibility Notes
Trifoliate orange (Poncirus trifoliata) Script error: No such module "convert".[1] Inedible fresh Used as rootstock and will freely hybridize with true citrus.
Ichang papeda (Citrus ichangensis) Script error: No such module "convert". Inedible fresh Parent to a number of hybrids, including the yuzu, sudachi, ichang lemon/shangjuan, and others.
Jiouyuezao mandarin (Citrus reticulata 'Jiouyuezao') Script error: No such module "convert".[2] Edible Long cultivated in China
Kumquat (Citrus japonica) Script error: No such module "convert".[3] Edible Fruit eaten whole with a sweet skin and sour pulp.

Chinotto (Citrus myrtifolia) Script error: No such module "convert". Used in cooking, too bitter to eat raw. Edible Long cultivated in Southern Italy, Malta and Libya.

Interspecific hybrids

Interspecific hybrid varieties considered cold hardy, ordered from most to least hardy:

Name Hardiness Edibility Notes
Citrandarin (Citrus reticulata × Poncirus trifoliata) Script error: No such module "convert". Semi-edible 'Changsha' citrandarin is the hardiest citrus hybrid.
Citrumelo (Citrus × paradisi × Poncirus trifoliata) Script error: No such module "convert". Semi-edible 'Dunstan' is considered the most edible citrumelo.
Citrange (Citrus × sinensis × Poncirus trifoliata) Script error: No such module "convert".[4] Semi-edible 'Rusk' is considered the most edible citrange.

Orangequat (Citrus sinensis × Citrus japonica) Script error: No such module "convert". Edible 'Nippon' is favored for edibility and hardiness.
