David Austin roses have another popular variety that has sported frequently.. 'Mary Rose', if any of you have it... its sports are 'Redoute', and 'Winchester Cathedral',.. all the same rose, different shades of pink or white... sometimes with 'Winchester Cathedral' it will sport back to 'Mary Rose' by producing stems with pink blooms on an otherwise white rose...
Jason-3 in a post earlier said he had 3 x 'Mme Isaac Pereire' roses... this sported to a rose called 'Mme. Ernest Calvat', which is a lighter pink... or some speculate that the sport occurred the other way around...
Loving the rose education, @Marlorena, keep it coming!
My Susan Williams Ellis is about to enter it’s second year, so early days yet, but it hasn’t been particularly floriferous or fragrant so far, but it is in a pot, which probably gets too hot, so I think I will try and make space for it in a border.
Regarding strains of blackspot, do you know what strains are present in Spain and what effect that would have on David Austin roses? I do seem to suffer quite badly from blackspot and have been blaming my tropical summer rains. Its lovely to see all the healthy foliage at the moment but I know it won’t last!
Mountainous Northern Catalunya, Spain. Hot summers, cold winters.
Nollie... no I'm sorry I don't know how many Spain has.. there are 5 strains in N. Europe altogether... do you get much blackspot then? it needs humidity to be fairly high with temps from 68F to about 86F... black spot fungus cannot survive in temps lower or higher than these... plus humid air is needed...
If you only have one or two roses, and you get up very early in the morning, it can help if you just run the hose over your rose leafage, first thing, it can remove any fungus spores that have rested during the night, waiting for temps to rise... the late Peter Beales advised to do that... organic method...
Fascinating stuff @Marlorena ...funnily enough I looked at MmeE rnest Calvat as it came into my filter on PB website. Can I ask if it had the same fragrance as Mme Isaac Pereire? As the colour is very pretty indeed
Daniel... no it doesn't affect the original rose at all.. sometimes I think it would be fun to plant a rose and all its sports together, so you get a mixture of colours on different bushes which are in all other respects, the same plant...
Do any of you grow 'New Dawn'?.... it's a rambler..
Hi Jason.... yes the fragrance is the same,... some people describe it as 'hypnotic'... also some growers report that 'Mme Ernest Calvat' has better disease resistance than its parent plant..
You got room for both? of course you have …[silly question on my part]...
Hi Marlorena, yes I do get temperatures higher than that and it can get quite humid in summer and I do get a lot of blackspot. I don’t mind how a few spots look but it can quickly defoliate the more susceptible roses, e.g. Darcy Bussell seems particularly prone but they all get it.
Thats interesting what you/Peter Beales say about running the hose over the foliage in the early morning, I understood you should try to avoid spraying the foliage with water because advice is often to water with a watering can at the roots to avoid splashing, which can cause BS! Soon as the first BS appears, I will try that on a few as an experiment! I guess the moisture would quickly evaporate as soon as it warms up...

Regarding Mary Rose which I've had in my garden for at least 10 years, some years the flowers are all the usual medium pink of Mary Rose, some years there are blooms of the pale pink of Redoubte and white blooms of Winchester Cathedral mixed in with the usual Mary Rose blooms and sometimes there are just one or the other mixed in with Mary Rose. I don't think DA sell Redoubte now - perhaps it too often reverted to Mary Rose. The scent improves as the flower develops and is very strong and unique to my nose.

does the sports affect the main plant at all?
