Full List of Cold hardy Citrus

Cold Hardy Citrus
From Wikipedia, the free encyclopedia
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 hybrids typically described as cold-hardy generally display an ability to withstand wintertime temperatures below âÂÂ5 to âÂÂ10 �C (23 to 14 �F). 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.

Place varieties of true citrus considered cold hardy here. Order list from most to least hardy. Of course hardiness and edibility are subjective. Keep notes short.
