Thanks for your comments re roses for poor soil @Marlorena, the single flowers I suppose are another factor making them better in exposed positions. I have Amber flower carpet, it doesn't exactly set me on fire, but it is rudely healthy in a rather dank part of the garden, getting sweated on by other plants.
Hi all rose lovers. Here is my last Guinee red rose. ( could be wrong about the name, but I don’t think so) The perfume is the best ever for my sense of smell. The colour is more velvet dark red than my iPad shows. More like the reflection in the glass. Happy gardening Val
Most of leaves on my The Generous Gardener look normal.
But some clusters look like this:
This isn’t a recent change, they’ve been like this all summer.
Some of the leaves started out all crispy and crinkly and then grew discoloured.
GG was really swamped by aphids though earlier this year, so I assumed it was just a result of damage from those. However some of the leaves that have ended up with these yellowy patterning are newer and started growing after the aphids had gone.
I've been looking on some European nurseries because they are the only nurseries with roses I desperately want (a typical helpmefind craze - I find something and must have it no matter the cost and hassle) but I am waiting for the outcome of Brexit or maybe even for late winter to give myself more time to think what to order and when to plant it.
My question is, do all European nurseries (or north-west European nurseries) use rosa canina laxa as rootstock for all roses, including old roses?
Not all of them do, no.... there are some that only use 'Laxa' [Fabien Ducher], like here, but others like Tuincentrum that use a variety of rootstocks.... you would have to email the nursery to ask which stock they are using for any roses you order.... about 3 years ago TL were using 3 different kinds... all various strains of R. canina… namely... ..canina 'Inermis'.... canina inermis 'Clou'... and 'Schmids Ideal..... all these selections have been developed over the years as they come true from seeds and are uniform in character.... they are also preferred by some nurseries, especially Schmids Ideal as it's hardier than Laxa which can survive -30C - more than enough for us... but SI goes down to about -50C I think... and is the preferred rootstock used for Russia and East European gardeners... so nurseries selling to those regions will likely be using that stock...
Schimids Ideal is actually very good judging from the one rose I've had on it... it didn't sucker and produced good growth.... I wouldn't worry about any of those rootstocks actually... but I do not care for the straight R. canina… I think it suckers too much... the selections have a better reputation...
Some might use R. multiflora... they do here in UK but for roses used for exhibition purposes as it encourages long straight stems suitable for the purpose... however this rootstock does not last long.. maybe 15 years or so and is not tolerant of alkaline soils.... Laxa will go 40 - 50 years and grows on anything...
This information I have compiled from correspondence over the last few years from nurseries.. Tuincentrum Lottum… Bierkreek…. and Sechzen Eichen Rosenschatz in Germany... I do not know what Rosaplant in Poland use or any of the Italian nurseries...
@edhelka … as you have an interest in old roses, especially from the less well known classes.... you might be interested in the offerings from Roseraie du Desert who are in SW France... all their roses are own roots, not rootstock and they have a vast selection although some may not grow so well here.... they've been up for sale for some time but may still be in business.... they are British/Canadian so language is not a problem... I've had several off them... all good roses with well developed roots...

Its a pain though! If this had been a week ago I could have got one in flower. But they have cut all of their roses right back.
So I just got a pot of sticks!

Is it anything to worry about?
Not sure what is causing that, perhaps a mineral deficiency?
