I'm glad to hear somebody else with this concern. I offer no solutions but I love a good rant so here goes.

In my opinion, the current situation is intractable. It's like a virus in the wild. You can slow it down but you can never get rid of it. We just muddle along as best we can and weed out the impostors as we discover them, hopefully before handing offsets out to other enthusiasts so we don't make the problem worse. Making the situation worse is (my pet peeve) so many cultivars are so similar that no expert on the planet can tell them apart. There are too, too many.

I'll be hiding under my desk for the next several days.
