Hardiness −8 °C. Municipality by municipality, depending on how cautious you are about frost. See the page “Moro Orange – Blood orange”

Why choose a risk profile?

Standard hardiness zones (USDA) give an average, but a citrus tree dies of the coldest night it goes through. So choose your profile according to your project: rather Conservative or Cautious for an orchard, Gambler, or even Daredevil, for a garden. If in doubt, choose Cautious: the cold that comes back about one winter in ten.
