And the aptly named mossy rose galls. And they can take over a plant. Somewhere there's a reference to their use in folk medicine (with or without the wasp inside). Here is a link that might be useful: Mossy rose galls

As Mike said above, tree roses are almost always composed of 2 grafts that join 3 distinct 'pieces': The rootstock, the interstock (trunk) & the scion (the portion that produces the bloom). If your plant was a 36-inch rose tree from J&P it's almost certain that the interstock was Grifferaie grafted onto Dr Huey rootstock. If it was a 24-inch tree, it's conceivable that both the roots & the interstock were Dr Huey, altho Grifferaie is often used on those too. If you planted the tree deeply enough, I suppose it would be possible for the interstock to strike roots, but I think that's unlikely. I seriously doubt that there's any possibility De la Grifferaie will be the variety that comes back in your garden. I agree with berndoodle that you can expect Dr Huey to be making another of his unwelcome house calls.

Thats dedication Ed! So nice to see the lengths people go to in order to have what would not normally be grown in their areas! When looking at propagation techniques for palm trees I found a bunch of videos on youtube produced by a canadian on the pacific coast. This guy and in his town there are all kinds of palm trees! Apparently there is a microclimate there. Too cool. That red was my MIL so i can't check it, but will the next time I visit. I don't think it had red stems but could be wrong........going from a poor memory. Merkity, Cherie is beautiful. Does anyone know why the leaves "cup" up like this? One of my newest plants does this and I haven't noticed any other plants doing this, but the leaves on this plant are very much unlike my other plants. Darren

The galls are actually the plant's response to the bacterium's presence in the past. Whether it continues to exist in your soil or not, I don't know. It appears very common and wide spread in the desert south west, perhaps other areas too. Supposedly, what is required is a wound at or below the soil level to permit the bacteria entry into the plant. Therefore, it would seem unwise to prune roots when planting or to influence a plant's performance. It would also seem very unwise to "cultivate" your garden soil anywhere there may be rose feeder roots as those "wounds" could, potentially permit any bacteria entry into the plant. Similarly, "companion plantings" might also be potentially damaging, particularly in established rose beds. Digging a hole, of any size, could result in "wounded" rose roots, providing entry to possible infection by the bacterium. And, what about gopher vole or mole damage to the roots? Moles may not eat the roots, but they do dig through them and can cause "wounds" to root tissue. There are instructions all over suggesting you remove and replace the soil from a spot where a galled plant has been removed, though if it's possible the bacterium exists in your soil, what benefit would there be to replacing that soil in that spot? And, could the situation be similar to that of RMV, where, though you've never SEEN symptoms, the causal agent has been present for a long time prior to the expression of symptoms? I can't give you absolute answers, but I do raise these other questions to possibly point out that, other than using something like Galltrol and insuring there will never be any damage to the rose tissues where they may become infected, there really may not be much, if anything, you can do to prevent galls.
