From what I've read, currants and gooseberries are so botanically similar that simply banning the cultivation of currants does nothing to stem white pine blister rust because gooseberries grow wild in so many places. If a nursery won't ship them to NC I willThey have not been produced widely in the U.S. for many reasons. The major reason being a federal ban on plants as they thought white pine blister rust could be eliminated by eradication of the alternative host (currants). This was not the case and the federal ban was lifted. However, local bans are still in effect in some regional areas.
