I have no idea. However, my best survival surprise was climbing Clothilde Soupert that was planted on the south-facing wall of my house so it gained from the thermal Mass. It was smaller, but with some long canes which got buried accidentally under oak leaves. There was no dieback in -7 nights and single-digit days. FWIW.

My worst were at the foot of a north-facing wall. I think in this case the cold winds and air fell to the bottom creating a colder Zone. These were all Hybrid Musks.

I believe giving your Quick Silver the maximum amount of sunlight possible to get it robust and husky will give it the best chance of experiencing the least amount of winter damage.

If the spot it is in now affords it the most sunlight, I would leave it there.

It's really a shame that this rose isn't available here in Europe. I bet that it would do great in Italy, and in many other parts of Europe,much of which has a climate that is far milder than that of the USA.

The north side would get just as much sunlight I think, but it would be earlier in the day - it would be out of direct sun by 2 pm. Vaporvac, the north bed will be farther from the house, so I think I'd avoid a 'cold sink'. I think I'll be leaving it where it is and watch it carefully next spring. I'll be able to compare rose survival and hardiness between all three spots then. It wouldn't be too far behind the other climbers, methinks, if I moved it then. Thanks guys!

Bart... You aren't missing anything by not having Quicksilver. It is without scent. I know this comment may trigger some Quicksilver Rose lovers but it's not something I want taking prime space.

It's generally a healthy and good blooming plant otherwise. But it's boring without a fragrance for me. Mine is either going to be given away to an unsuspecting person or tossed into the trash if there's no one willing to have it.

For me, also, Quick Silver does have a good scent. Fragrance a solid 3 on a scale of 1-10, most notable before 9 am & in the evening here. Top note of sweet violet floating on a vanilla base with more floral hints. The clay based loam here is rich in minerals, which may contribute to stronger scent & coloration for roses. If your soil is sandy, DVS, you might try fertilizing Quick Silver with a blend of micro nutrients including minerals to promote scent in yours. Many report fragrance not coming in for several years on roses across the board & advancing with maturity. Just a thought...

Grown Quick Silver for 3 years now & added more each season, so I'm really charmed by its personality. A rose that just gets better as it matures & continues to delight! Sue

Bart, have you tried contacting RosTom through HMF? Here's a photo of Quick Silver at HMF posted by RosTom, breeder in Germany. If you click that member name above the photo, it takes you to their profile page. You can PM them from that page. Good luck! Sue http://www.helpmefind.com/rose/l.php?l=21.294856 

Thank you Vasue! I tried ,but I guess the site doesn't permit me to message because I'm not a member,and I can't figure out how to sign up as a member; can you help me?

Go to HMF rose page and there is an icon in the upper-right hand corner that says 'how do I?'. Click on it and it has a list of questions such as how do I sign up for my free HMF membership. Just follow those directions and you should be good.

AC91z6, I find Quicksilver is better at survival than other lavenders, but they're notoriously not hardy. I have virtually no chance at surviving canes on Quicksilver in my zone 5 winters so I'm just considering this one a large shrub. In your zone I'd opt for the most warmth over the winter since I think it's the cold per se that does in the canes on this rose rather than the freeze/thaw cycles. The north side is more likely to be a virtual zone colder than your regular zone which for you is zone 5. Like me then, you'd get no surviving cane on that side of the house.

YMMV, but that's my recommendation - leave it on the south side.

This is the 3rd year for mine. It's planted at the far edge of my garden with no protection and sun all day. A picket fence was just finished for that row of climbers to clamber over or lean on. Climbers don't usually climb very far in my climate. I'm satisfied growing it as a shrub, but it has a couple of longish canes. Also, this area is known for it's freeze/thaw cycles all winter, but Quicksilver has impressed me with less winter dieback than I expected. My guess is that it likes the sunny spot.

QS is great here so far. Less black spot than most my other blue/lavender shades. Poseidon is also pretty much black spot free.

Once again, thanks,Vasue. I joined HMF...

I'm glad that was helpful in navigating their site. Did you join under Bart?

bart - The image you saw at HMF from Germany was taken at my nursery here in Oregon- I recognize this image. I hope that they do start to sell it Europe as it is a wonderful rose. It is actually quite good in cold wet soil as we did a trial in a site where few roses survive and it did better than any rose we ever planted in that site.

Vaporvac, when I tried using "bart" HMF said that it was already taken. So I used "eibhlin", which is my real name (eileen) in Gaelic. I figured THAT would not have been already taken, lol!

Chris, I so hope too that they start offering it here in Europe. So much of Europe has a milder climate than that of the US,and from this thread itself one gathers that this rose might be slighly shy of cold (maybe I'm totally wrong, but I get this idea that a lot of the lavender-coloured roses tend to be happier in warmer climates???). It would probably do so well here in southern Europe. RosTom made some comments that they were unsure of it's vigour and resistance to disease in Germany,but if Cynthia in Nebraska is able to grow it decently,I really think it would do fine in Germany.
