How badly can this (and the similar Alba Maxima) be affected by rust, and does it cause a lot of infections in nearby plants? I understand that this rose itself is tough enough to shrug it off, but I'm worried it might cause me problems elsewhere where I don't currently have any.

Horticulturally we recognize that all roses evolved where flowers sported or descended from single to semi-double to double flowered varieties. So we know that Rosa centifolia is descended from a single flowered variety even though that ancestor is extinct. In a similar fashion we must know when presented with two roses; alba semi-plena and alba maxima that maxima must be a sport of semi-plena especially when both roses sport the other regularly. So why does HMF show semi-plena as a sport of maxima and not the other way around as well? My contention is that they are both sports of each other.
Which came first? The chicken or the egg.

The parentages are based on the cited references from rose literature. These show semi-plena as a sport of Maxima. But you are right, both roses have been around such a long time (see reference if 1629) that we do not know which is the original type.

Thank you for replying. I think its important to note when rose literature conflicts with other possible sources like horticultural science. Hundreds of years ago roses that were considered inferior were expunged everywhere which no doubt resulted in the extinction of many varieties such as the original five petaled Rosa centifolia. The literature could have been changed as well. We'll just have to wait and see if DNA analysis can determine which came first. Not that it matters except from an purely intellectual perspective.

Yes, I keep wishing we could do DNA analysis on such-and-such a rose, and then I remember that a third of the world doesn't have clean drinking water, and HMF lists 80,000-odd rose cultivars.

Much of the world could have clean drinking water except that so many governments of the world don't seem to consider it important. Rose DNA analysis I think will take a whole lot less time. Damning isn't it? I was investing in a company that planned to provide clean drinking water to countries in need all over the world but it failed due to the recession. DNA analysis of 80,000 cultivars of rose though, I believe there would be much less resistance to funding that.

This is admittedly very late, but I must say that it is certainly not unheard of for a seed-borne double-flowered rose to sport into a semi-double form. The most obvious which comes to mind is 'Souvenir de la Malmaison' sporting to 'Souvenir de St. Anne's'. So while I understand the reasoning that single is the default over double with regards to wild species, the same is not necessarily the case with cultivated varieties.
