I have a few 'Temple Bells' x 'Therese Bugnet' seedlings here and have tried in the past to get other rugosa (e.g. 'Ann Endt') to marry with 'Temple Bells'. The result has been either nothing or poor, failure-to-thrive, offspring. One TB x 'Therese Bugnet' seedling has started to kick on a bit but unfortunately it doesn't like the hot summers here and is starting to show disease issues. Maybe it will do better in the ground??? I think there are a few significant compatibility issues between rugosa and wichurana and a lot will need to be done to find one that isn't crippled by these issues.

'Temple Bells' crosses very nicely with most moderns, however, to make a lot of miniatures that show excellent health. Crown gall issues may be avoided by using resistant versions of modern repeating floribunda etc. If you can, I would also recommend crossing TB with other species from within the Synstylae section to try and overcome these crown gall issues. TB does a good job of taming such seedlings (a little) and can then be used as you would use TB though the repeating gene(s) might be lost. I have TB x Rosa sinowilsonii seedlings this season that are looking outstanding and I can hardly wait to get these to flowering stage to see what they can achieve. They look exactly like sinowilsonii except everything is in miniature! Really healthy, vigorous and so cute I just wanna squeeze their cheeks every time I see them. I also have TB x a thornless multiflora that is very healthy and once flowering. This season I am going to collect its OP hips to see if I can recover the thornlessness.

I'm just thankfull that I don't seem to have crown gall here... Apparently it IS here but I've never seen it!

The results have been very worthwhile but you need to have the room the grow these out as they probably will be quite large.
