Happy New Year to all!
I grow Honorine de Brabant now, and have done so for the last 10 years, and have read on here over the years about how it is not the cleanest rose and can pass on mildew susceptibility to its offspring... but to be honest... I haven't seen any of that. It can pass on its stripes if you do enough crosses with it (it doesn't give them up easily) and here (Tasmania, Australia) it grows own root as a large, nicely shaped, shrub with absolutely no care or attention and just does its thing. It does like its water and maybe that's why mine does well because it is growing adjacent to a wet area and it never really dries out like most areas in the gardens do. I have it down to use as seed parent in the next few days with 'Knock Out' because I have a feeling that could be awesome... working in the size, flower power and health of KO in with size (I like big, shapely, roses ;) ) , stripes, and fertility of HdB. I have also been playing with the idea of going back to 'Fredinand Pichard' again... but compared to HdB it does not flower enough to be useful and the two actually seem quite similar anyway making them interchangeable in their use. I don't like the lack of substance in the petals of HdB and have noticed that this is passed on readily. The flowers will often ball, or get botrytis, or shrivel and brown off in hot weather.
