'Veilchenblau' rose Reviews & Comments

Initial post 27 JUL 21 by Mervey

Hello, I just discovered a strange new stem growing out of one of my Veilchenblau stem. It's a "newborn" (3-4 days old), foliage and stem resemble Veilchenblau but all brownish-redish. Did someone have already experienced this ? Thank you very much.	REPLY

You might, I say might, have Rose Rosette disease. Might there be a rose expert you near where you live whom you could consult? Has RRD shown up in your area? Does the stem resemble new growth on the same plant?	REPLY

Thank you, I didn't know what is Rose Rosette Disease so I searched for and found "provenwinners . com" for explanation. No, this stem is exactly the same as the whole plant and new growths except the colour. All the other new growths are exactly green.	REPLY

Many young shoots (and foliage) have reddish colour - it is a higher anthocyanin content as protection against UV-light). Wait a while to see if the fresh shoot turns green.	REPLY

Thank you,

I didn't know that. Until now, all my Veilchenblau new stems grew exactly green and this is the only one which is growing brown. That said, the first leaf at the base of the stem have turned green.
Wait and see... I marked it with fluo pink elastics for later recognition. I'll post other photos for comparison.

Well, the first 5 photos are of the brown stem, the last two of normal green stems :

It looks like normal new reddish growth to me. The reddish color might be more common than you remember, or it could be weather-related, if conditions there have been hotter/cooler or wetter/drier than usual where you are?	REPLY

Thank you scvirginia,

Yes, looks normal but reddish. There are lots of weather changes in France since early May and my region, Brittany, doesn't make exception but it is far to be the first time. I took a look at the plant this morning, every new shoot grows green except this one. Do you think this could be the result of a weather change ? Have you ever heard of any Veilchenblau's sport existance (just dreaming... haha !) ?

I can't provide links, but there are several good photos amongst the Veilchenblau photos of reddish new growth for comparison.

One is from December 2010 (uploaded January 2011), another is from June 2012 (uploaded August 2012), and another, provided by jedmar, is earlier and has no date.

I remember being alarmed by fire-engine-red growth on a Climbing Cecile Brunner once. I don't recall seeing growth that red on that plant before or since, but I might have missed other examples, or just not remembered them.

Teas and plants descended from them, like Cecile Brunner, are especially likely to have red new growth. For example, the spring flush on "Agnes Saffron's Tea", photo below. Unfortunately it attracts parrots, which have learnt that new growth means that sugary sap can be found in them.	REPLY

Yes, Climbing Cecile usually has reddish new growth, but this was a remarkably bright red, and I did have a few moments' panic that it might have RRD. It turned green after a week or so, though. We don't have your difficulties with opportunistic parrots. There was once a Carolina Parakeet in these parts, but it was hunted to extinction long before I was born...	REPLY

Thank you !

Would Veilchenblau be a hybrid tea ? I have read the "References" and it is just a Crimson Rambler's seedling, a multiflora hybrid. Though some references mention 'Erinnerung an Brod' as the other parent, perpetual hybrid. Is this class descend from Tea ?

I didn't kow about parrots' taste for sugar.
We, in France, don't naturally have any parrot species but there is a new pest invading the western Europe : the collared parakeet (Psittacula krameri). An imported lot of 50 indivuals (France) fleed away few decades ago from Roissy airport and since then they multiplied strongly, not being predated, having no killing disease, not being killed by our no longer too cold winters, they nest in the tree holes preventing our european species to reproduce normally, they eat everything they can. And the worst is that they are very intelligent...
Here is a screenshot of a youtube video (L'invasion des perruches à collier à l'est de la métropole lilloise) :

"fleed away"? I love it! The boring, correct English is 'fled' but 'fleed' is so much better and more descriptive. The little parrots are cute. No predators? What about housecats? I understand adorable pets were responsible for a number of small animal extinctions on tropical islands.	REPLY

Sorry, being French, English language is not very natural to me. Once I wrote it, I hesitated and finally let it like that. Glad you love my mistake !

Yes, these animals are cute... in the wild in their original countries. They are millions today in Europe, they live in the trees and housecats are... house cats. These birds are seeds and vegetables eaters, they already have started to attack the vegetable crops (in England as I know). I can't imagine the disaster if they start to eat weaten, barley... in the fields before they are ready to be harvested. Like grasshoppers.

Alas, most humans don't think enough about the consequences of their acts, that why this planet is so sick. Because of the dodo's extinction, the forest can not regenerate itself. And so on...

Thank you for posting, I was a bit affraid that I turned off topic too much !

I'm sorry I confused things. There is nothing in the recorded parentage to suggest Teas in the background of Veilchenblau. In Australia, introduced cats (tame and especially feral) are calculated to kill a million native birds, lizards or other animals per day. Cats are hunters, regardless of what their owners say.

Thank you ! I just took a look at all the pictures you mentionned and YES it is exactly that, the one which made me understand better being the stem posted by jedmar but all are extremely helpful. So, the good thing is I don't have to worry. But my dream gone away (lol) !	REPLY
