rose rosette on native roses
I understand that natives are supposed to be resistant (immune?) to rose rosette. I have a friend who had a large colony of R. palustris growing with R. multiflora in a marshy area. The multiflora has about died out from rose rosette before she learned to recognize it. Much of the R. palustris has also died off. Compounding factors are active voles and careful use of an organic herbicide just upstream.
Ann? Anyone? Have you seen rosette on R. palustris or other natives? My friend would like to re-establish the R. palustris,but not if it's likely to become infected. Thanks.
