Factsheet F14: Citrus and citrange, hardy


By ‘hardy’, this article is limited in scope to those species and varieties which are hardy in zone 8 (ie hardy down to average winter minimum temperatures of between -7 and -12°C). Most of the well known Citrus species, like the oranges, grapefruit, lemons etc are only hardy to zone 9 (-1 to -6°C) and have little hope of surviving outdoors in temperate climates where frosts are common; however, occasionally, hardier varieties of these tender species do exist.
