The federal ban on importing Ribes plants into the US may have been lifted, but fourteen (14!) states (mostly in the northeast and upper midwest) still have varying restrictions on planting various Ribes.

This species is an alternate host to white pine blister rust, a serious problem for a major timber crop in the east. Some Ribes species and some Ribes cultivars of susceptible species are resistant to the disease.

Before planting this in the east and upper midwest, consult your state's Department of Natural Resources to find out whether planting this species is legal.
