Does anyone know if they have developed a white knockout rose yet? We
have a spot that would be ideal for them in the landscape but the
flowers need to be white. Are there any other roses (white) that
approach knockout in resistance to blackspot?
Thanks

No white knockouts yet, but they are working on it , I am sure.

here is the link to the knockout roses home site:
