The following hybrids seem to be more resistant to black spot than most others: 'Brandy', 'Iceberg', Pristine', and 'Gold Medal'. For resistance to powdery mildew try these: 'Gold Medal', 'Pristine', 'Honor', 'Voodoo'. For resistance to rust: 'Gold Medal', 'Honor', 'Pristine' and 'Iceberg'. Good luck with the roses! |
