HelpMeFind's future is in your hands - Please do not take this unique resource for granted.

Your support of HelpMeFind is urgently needed. HelpMeFind, like all websites, needs funding to survive. We have set a premium-membership yearly subscription amount as low as possible to make user-community funding viable.

We are grateful to the many members who have signed up so far, but the number of premium-membership members remains too small for us to sustain the current support and development level. If you value HelpMeFind and want to see it continue we need your support too.

Yearly membership is only $2.00 per month and adds a host of additional features, and numerous planned enhancements, to take full advantage of the power and convenience of HelpMeFind. Click here to start your premium membership..

We of course also welcome donations of any amount. Click here to make a donation. Donations of $24 or more receive a thank-you gift of a 1-year premium membership.

As far as we have come, we feel HelpMeFind is still in its infancy. With your support we have so much more to accomplish.

This rose was issued an ADR designation in 2014. Said to be 100% immune to fungal disease and winter hardy too zone 5. Incredibly beautiful and can only hope it finds its way too America. I'm unaware of how many black spot races a rose is exposed to during ADR testing. I will say that of the ADR roses that are in my garden. They have had excellent health and performance.

I've had this rose for one (wet and disease-friendly) growing season in Sweden so far and it has unfortunately failed to live up to the 100% disease resistance statement in my climate. While resistance against black spot and powdery mildew has been very good, it has been susceptible to rust and also stem canker (possibly downy mildew as shown on the attached picture)...

The same spots, I saw on Home Run and I uploaded some photo's of it at the comment for that rose recently.

Yeah, it comes from Knock Out. But in all honesty, it has never bothered me. Only us plant geeks stare at stems in the winter.

The leaves get the same fungus too, fall off, the plants deteriorate and or die.

Hmm, interesting. The stems with those spots here don't defoliate. Just the stem disfiguration begins in September and continues until January.

Not only the stems defoliate during the season, next season, those stems die and the plants have to make new-ones like mad from scratch... and the whole cycle continues, till death(of that rose) do us part.
