Only one dubious plant since 2010? You really do have it good. Just this year I've had the dubious 'Pacific Knight' which I'm now 70% confident is correct, but noone can really say. And I received a definitely wrong 'Fuego' from a trusted source. And recently through Lynn discovered that my (and her) 'Strider' is probably actually a 'Bronco'. Last year I got the wrong 'Raspberry Ice' from Cistus Nursery which I would not consider a trusted source. I would bet some serious cash that there are others lurking about in my garden of roughly 100 cultivars. But who could really say? It's impossible for me to ever know. I don't lose any sleep over it but that's just me, maybe somebody else takes it more seriously.
I don't think anyone is saying that our good sources are irresponsible, but it wouldn't surprise me if each and every one of them has some incorrect stock. One label mix-up results in dozens of wrong shipments which gets multiplied into even more as hobbyists and vendors propagate them and send them along. It's unrealistic to think we can get all this 100% correct... I get that.
As I think about this... in the end I agree with Kevin... we do have it pretty good. But it could be better and I still think it's too easy to make new introductions. But that's just one amateur's opinion.
