Since I have been unable to locate a full and recent list of state legality regarding plants of the Ribes genus, I compiled my own comprehensive list. Like the laws themselves, this list is dynamic so please contact me if any of the information here is out of date. Please check with your local extension office for confirmation before getting involved with the Ribes genus in any regard.
Summarized: Ribes plants really are forbidden fruit to some people. Residents of New Hampshire, North Carolina and West Virginia are completely out of luck as those states enforce a statewide ban on all Ribes species. Delaware, Massachusetts, New Jersey and Rhode Island enforce a permit system. Most other states ban Ribes cultivars that are not resistant to the White Pine Blister Rust (WPBR) pathogen but below is the complete breakdown.
