Disease Profile: the viral Rose Rosette Disease (RRD)
Comments (3)If one of the wild roses has an immunity against the virus, it may be possible that grafting ornamental roses to that wild rose (used as understock) may transfer the immunity. "if silenced rootstock can efficiently transmit the silencing signal to non-transformed scions, as has already been demonstrated in herbaceous plants."

Took some cuttings for analysis to get confirmation. Sadface on , as these boxwoods I have nurtured since they 3G sized to full grown....and they grow like a measly few inches per year at most.
