I cannot believe the Powdery Mildew problems I am having with this rose, if it was one of mine that I had bred, it would have been shovelled years ago.

Is it thirsty Warren? Rain usually gets rid of mildew.

Hi Patricia;
It should n't be, I flood irragate the rows, I have a lot of roses which I bred around them and they show no signs of this Mildew. I have a Baronne Henriette De Snoy which is just as bad. These are cultivars which I bought in to breed some fungus resistance, but now I am having some serious thoughts on using them. As I said to some one a while ago , I do not think a lot of Teas are pure Teas and when you see the unknown in the parentage , it makes you wonder.
Did you go to the rose convention in Perth?
cheers Warren

A pity about the mildew.
No - too far away for me Warren. But Richard and Ruth made it down here and I heard all about your weekly phone calls to each other talking roses.

Many Teas that seem quite prone to mildew when young seem to get much more resistant when they build up their root system and mature. I have no experience with this one though.

Good point NikosR. Have we ever seen an old foundling tea that was covered with mildew and looking disgusting? I haven't. The old ones I have seen looked so beautiful - which gives me much hope for my old age when I really do have to neglect them.

I'm confued regarding the references on this rose. All of the references state that it was bred by Eugene Hardy, but you have it listed as being bred by Guerin. Also, wondering about the zone 5b hardiness for a Tea? Thanks for any insight :)

Let us say that all the "new" references state that Hardy has bred this rose: the earliest attribution to Hardy is by Ellwanger in 1882 and all later authors have followed him. However, there is a reference from 1836 which lists 'Silène' under roses obtained in Anjou by M. Guérin, as well as an earlier source from 1835, which also mentions Guérin and the first blooming in 1834. The date of 1839 quoted by Ellwanger probably refers to the mention by Buist of 'Bon Silène'. We take these two names as being synonyms.

That makes sense Jedmar. If the rose was discussed 50 years prior to Hardy's breeding program, it would have been difficult for him to be the breeder. Thank you!

I really didn't like the bloom form on Bon Silene. The petals grew in all directions with no apparent symmetry or attractiveness. The color was great though.
