So much to catch up on after having my niece for several days over the holiday week! She's 7, so plenty of energy to burn - keeps Aunt AC busy!
Lots of good information so far! Kesroses, we have the same issue with multiflora invasiveness here. If any of my roses from Hortico make it, I'll try to pay attention for multiflora suckers. I've already lost two, but that's due to our weather being cold forever and me getting sick when they first came so they got to sit in a water bucket in the garage for longer than was probably good for them.
Roseblush, I did read somewhere on Gardenweb (from Henry, if any other Gardenweb escapees recognize the resident scientist) that some research had shown a correlation between multiflora grafts and RRD susceptibility, but it wasn't definitive - more a 'we found something that warrants further research'. I don't think I'd let it scare me away from multiflora rootstock, especially as my only other real choice is Huey. I'm burying deep enough they'll probably go own-root at some point, and the study didn't look at whether the roses had gone own-root (how long could the increased risk last?) or (and I'm suspecting this, given what Kesroses said about multiflora suckering) if the rootstock had suckered and the rose caught RRD from those stems.
Scvirginia, I think you're right about it being simpler to just use one rootsock, even if two or three work well for your area in general. Some roses may have done better on R. laevigata than R. fortuniana, to use your examples, but unless they sold well enough for a nursery to maintain separate rootstock fields they would just fall out of commerce. Might explain why some roses vanished from some regions.
Steve, you make a good point about taking whatever rootstock is available
I've experienced the issue of bareroots struggling in cold zones due to being kept so long in storage - it's a good argument for just starting with plants. Do you think ARE's own-roots do better because they are two gallon, or that under-performers would just be culled from their offerings by a nursery growing them on that long?
Zuzu, I think you've won the 'grafted rose horror story of the year' - Holy quality control Batman, that's terrible. I hope they gave you a refund for that rose lemon.
I did want people to list experience with rootstock and scion/variety suckering - I'd like any newbies to know what options they have and what to expect, and for more experienced rosarians to have a heads up about any about other classes and older/antique roses they haven't tried yet.
Jerijen, that's good point - budded roses have declined in quality because good grafters are in short supply, and it's a labor intensive process to debud properly. I can't imagine trying to grow anything with gophers around - I think I'd be on the news for resorting to dynamite! Kudos to all you rosarians who garden in spite of the little pests.
The only consensus across regions I'm seeing for budded classes are HTs (for vigor, mostly from the 20th century) and Gallicas (for containment). For own-root it's other OGRs and some from a few breeders - Buck, Kordes, and Ping Lim (who is behind many of the Easy Elegance series).
For rootstocks I'm seeing Multiflora is good for naturally acidic-to-neutral soil, Fortuniana for warm zones. I don't have a lot of experience myself with Huey, but several experienced rosarians on HelpMeFind have commented that it does well in wet and clay soils.
Are any other rootstocks used anymore? I've read about 'Manetti', but only in historical information, and I think I've seen posts about people getting roses on 'Pink Cloud'/'Pink Clouds' or something like that - does anyone know of any sources that use something other than The Big Three?
