Thanks to those who wrote in reponse about cedar apple
rust on Liberty. I'm inclined to agree with Ed
Fackler that I might have gotten a mislabled scionwood
stick. I have some plant pathology training and was
able to find the rust spores with a microscope - I'm
pretty sure it's cedar apple rust on there and not
something else - so I think it was either mislabeled
or the resistance broke down somehow. I guess I'll
have to wait until it fruits...
