I grew it when I lived in Fl. as a hedge. Beautiful color, great foliage and some of the most wicked thorns you can find on a rose bush. 20 of them across the back 50' property line. It put a beautiful end to a problem I had with my neighbors large dog.
Do you seal your pruning cuts. If not look for a round hole any where the rose was pruned. If you find a hole, something put there larvae in there. Even leaf cutter bees will lay larvae in cut stems.They eat their way down where they over winter. When you see a hole in spring before you prune for the season. Cut till you see no hole. Then cut the cane in half just above that and you can see the tiny black developing bee larvae. Of course there are many types of bore insects that can affect roses.
Should that cane start to wilt the sooner you cut the better as if something is in their it will continue to munch it's way down. If only the flower or bud is wilting than something laid eggs in it. Take them off and discard in garbage. You would not want the eggs to develop.
Usually he type of borer that causes wilting tips is not the type that drills nursery chambers in cut cane ends. The latter is the Small Carpenter Bee. I tolerate these without any major problems. One borer that drills way down the cane after starting near the tip is the Raspberry Stem Sawfly, but I don't notice them before July.
See the excellent Baldo Villegas page for his discussion of borers.
A common problem with rugosa roses in the North is Rose Stem Girdler. They kill whole canes by tunneling under the bark in a swollen area. Look for these canes in mid to late summer, cut below the swollen area, and bag or burn it. Otherwise the larvae survive winter and become adults that lay more eggs the following season.
Yes, I think you have to be a member on HMF to us the private messaging. I would encourage you to join because it's well worth it.
Dave really needs to get his roses out there. I looked at all his plants listed at HMF and they were all beautiful! Lots of them are stripes and have great form!
Oh my goodness!!! How can that rose NOT be out in commerce!!! It's exquisite!!!
I also decided (just now) to go look at his other roses (never thought about it until I read above). They're GORGEOUS!!!!!!! I can't believe he's not selling his roses. If those roses can't get into commerce, then nothing can.

I found these photographs of the Huntington on Hoov's blog: Huntington April 13, 2015. You have to scroll down until you get to the April 13, 2015 post. Thanks to Lynn and Hoov, I'm starting to appreciate those distance shots. They are quite something.
Do you think it could be First Class (Class Act)?
Opinions will vary, but I would leave it alone. Doesn't look active.
Thanks! That was my thought...but I've been wrong many time before. :)
