Whitecurrant (Ribes rubrum (white-fruited)) – hardiness zones in USDA, RHS, Canadian & Australian systems

Mild-flavoured albino form of redcurrant. Produces translucent ivory strigs of berries; less acidic than redcurrant, exceptional for clear jellies.

Hardiness ratings

Whitecurrant hardiness across the four zone systems
System	Rating	Temperature range	How to read it
USDA hardiness zone	Zone 3–8	−40 °C to −6.7 °C	Plant tolerates down to this zone
RHS hardiness rating	H7	down to −20 °C	Plant needs at least this level of cold tolerance
Canadian plant hardiness zone	Zone 3–8	−34 °C to −1 °C	Plant tolerates down to this zone
Australian (ANBG) zone	Zone 1–4	−15 °C to 5 °C	Plant tolerates down to this zone

Birds notice white fruit less than red — sometimes a more reliable crop than redcurrant
Same cultivation as redcurrant — prune to a permanent framework
