Hi Westgate,
If you go to the Antique Roses and (modern)Roses forum and search for disease resistance you will find lots of posts discussing this topic. I use suggestions from posters on the west coast as my starting point, and then expect to cycle through those to find the best for my particular siting. I have moved roses that were covered in mildew from one side of the house to another and they have been disease free in the new location. I have a main border in a poor circulation area with a section of it stretching the sun requirements of most roses. Perle d'Or is a wonderful rose that is disease free and blooms there. The Austin Jude the Obscure, the Teas Marechal Niel, Le Pactole, Souvenir de Pierre Notting, the China Mutabilis are all good for me... most of these are available online as own root plants.

All the ones I listed on your favorites thread are problem free for me. I apologize that I simply said foliage but what I meant was that they all pretty much have impeccable foliage with no spraying. No BS, no PM, no nuttin, honey :-)

Thanks for the help... I planted a Darlow's Enigma in a large pot next to a trellice, then got a message from a rose fan telling me NOT to put it in a pot! Too late, so we'll see what happens. I'm keeping the list of suggested roses, in case I lose my mind and decide to plant some more!

Westgate, can I ask where you found Darlow's Enigma? I wonder if most nurseries carry it. I noticed that Old Rose Nursery on Hornby has it. I do prefer roses that are grown on their own rootstock, the ones that are grafted always seem to escape the graft.

The armature of the "Enigma" can be wicked, excellent for pulling knit hats off for instance and it is not a small plant either - but its habit varies and, as always what you will experience depends on the total combination of factors at work in your particular situation.

This variety IS consistently clean in this area, but with many others what you will find in reading about results gotten with them is that there is no true consistency. Fungal strains mutate rapidly and vary from one location to the next, plant nutrition has also been said to play a role in fungal infestations of roses. I've noticed kinds not usually problematic in the ground here with nice infestations in nursery pots, where they may not have been kept adequately fertilized (here this seems to be the rule rather than the exception, at least at retail outlets where they often seem to want to minimize the money spent on the stock before it sells).

I just found this site, there are brief comments about disease resistance or the lack thereof; and many pictures of lovely roses. He lives in B.C., so he's definitely PNW.

I'm having a grand time browsing his site, as a newbie I haven't seen a whole lot of roses in the flesh so to speak.

I live in Portland, the "Rose City" and it is actually difficult to kill roses here! I never do anything to my roses, and I have many different kinds, and they all do just fine. I don't know how different the climate is where you are though.
