For some reason I thought daylily rust would be a major problem there in Japan, especially since they seem to have the host plant for rust growing there. I realize this info is from a web site, anyone know if it is for sure true? Why would they not have rust on cultivars just like here. I assume being it does show up on species that it is not the climate that is preventing it on cultivars?
"In Japan, daylily rust is commonly observed on wild Hemerocallis species but rust outbreaks have not been reported for daylily cultivars on residential properties or public botanical gardens. It is unclear why the disease has not been problematic in Japan."
