Black Walnut immune roses?
I want to buy some grafted black walnuts because I have had such poor luck grafting them myself (they are NOT cooperative!). I thought I'd go look see what species should be kept away from BW's and saw that multifloras are immune. Apparently not all roses do as well though, and I'd like to know if anyone has published a list of roses that do or do not do well with black walnuts, or if any of you have observations. Ann Peck says she planted her very happy hybrid musk thicket under the BW tree because she'd seen a multiflora thrive under it. So I guess it doesn't take all that much multiflora to protect them from the toxin. I have one tree that is doing well at the corner of the garden, my one successful graft, so it's not coming out. (The others I'll plant FAR away!) By sheer good luck my Pickering roses are planted in it's reach, all multiflora rootstocks. Maggie is there, small and moveable. The McCartney Rose (HT) is nearest to the tree... could this be why it's not done so well lately? I moved it this past weekend. Or why a china rose died even closer to the tree several years ago? Carefree Beauty and a wichuriania rambler are also very close, they seem fine. I know American Pillar can take it, but it's planted elsewhere.
I've been drooling over Quest-Riston's book on climbing roses. I prefer some scent, and not too many thorns (I'm a massage therapist and prefer not to shred my hands.) I love the photo of Geschwinds's Griseldis, if that helps. I prefer flowers that aren't too congested. I have Sander's white Rambler (yes, thorny and congested, but smells good) and Violette and Veilchenblau and Ghislaine and Tausandschon. Any other ideas? I see plenty of thornless climbers, and plenty of scented roses, though they don't always occur on the same plant, and then there is the problem of availability. I suppose polyanthas would do, but they usually don't have any smell. Just thought I'd pick your brains. I'm in Tennessee, plenty of disease here and wichurainias do better at resisting disease, but how do they do with black walnuts? Thanks. Donna
