Zone 3 hardy clematis
Comments (3)I have just such a growing season here in my zone 3 garden. I have MANY large flowered Jackmanii types in which are cut back hard and bloom freely on the current seasons new growth. I have had no problem with hardiness as most all my plants are grown up against the foundation of the house where the roots stay warm during winter. ALTHOUGH, I know many of these types are exceptionally hardy and can be grown in the open ground! My sister has several large flowered clematis, which survive and thrive being planted against her trailer where they receive NO additional heat as the place is without any foundation Her clematis are deeply planted and this is something I would strongly suggest for any clematis being growin in COLD climates! In zone 3 or colder, IÂd also HIGHLY recommend that the large flowered types be hilled up with a deep layer of peat moss. One can also grow the integrifolia types some of which produces rather large bell shaped flowers. Pamjat Serdsta is one such that performs very well for me without requiring any winter protection! Greg, there are all sorts of interesting and beautiful plants in which can be successfully grown in cold zone 3 ... others here will be able to guide you along with such choices.

Comments (17)Canadian Tire's clematis have come in rounded cardboard containers (stick attached) for a couple of years. I would imagine they're shipped the same way. I haven't noticed that any were broken, but if that's the way they're shipped, it probably does happen to a lot of them. Love the pics of Don's clematis! I wish all of mine looked so nice! The Pope did this year but the others have never looked like that. And my Ville de Lyons doesn't have the lighter stripes in the middle. Wonder if it's not what it said it was....See MoreHow do you hybridize trees zone 4-5 to zone 3?
Comments (7)>>I wonder If I graft the japanese maple onto a regular hardy maple in my climate?Grafting I'll use the example of roses here. Just like japanese maples, most roses are not hardy to zones 4 and lower. The are zone 5 and up. Hybrid tea for instance are not hardy but they are grafted onto hardy roots. Unfortuntely, this doesn't make them hardy in zone 4 and down, we have to protect them heavily so they will come back the year after and even then you run the risk of loosing them. Not because the root system is in danger but because the grafted part is. But even if you loose the grafted part during the winter, you still may have roses that will emerge from the root stock, below the grafting point. Of course, they wont be the same hybrid tea that you bought since that part died, but a hardy rose from the plant on which it was grafted. I would say the same rules would apply to japanese maples grafted onto hardy maple roots. You probably know the Explorer Serie roses. These roses are hybrids but are not grafted, they use their own roots to grow from and they are hardy to zone 3 and some to zone 2. I have 5 of them doing very well and they never needed any kind of winter protection and I never even thought about giving them any either (zone 4b QC, Canada). Why is this? The crosses were made between hardy species and/or cultivar from the the start and the breeding was done not to impart hardiness in the first place but to develop other caracteristics such as colors, trailing habits, short plants, diseases resistantce, etc. They probably used less hardy roses in their breeding program to bring in some new genes unvailable otherwise. Hybridizing If you cross two zone 5 plants like two acer palmatum, you'll end up with a bunch of other zone 5 plants. But if you cross a zone 2 plant with a zone 4 plant, you will probably end up with 80% of the plants hardy to zone 3, 10% hardy to zone 4 and 10% hardy to zone 2. Then if you take one of these new zone 3 hardy plant, roses for example and cross it back with a zone 2 rose, you may end up with a 50% zone 3 and 50% zone 2 stock. And if you cross back again one of these new zone 3 rose with a zone 2 rose, you may end up with a 75% zone 2 - 25% zone 3 ratio. These same rules would also apply to maples making crosses between 2 different species, one of them being the japanese maple for the first cross. The difference is here: in the example of roses I took, the desirable plant and the one used in every cross was a zone 2 and the goal was to bring a zone 4 plant to zone 2. With every cross I did I added some zone 2 hardiness to the gene pool. With the japanese maple, we would be working against the odds, the desirable plant and the one that should be used in every cross is a zone 5 plant and that would bring a zone 3 plant to a zone 5 only. And if I added more and more zone 3 maple, I would be loosing more and more of the japanese gene pool. Either way leads you away from the wanted result. And we haven't even said a word about what could be recessive of dominant in these crosses, which is also a very important factor to keep in mind. This can be observed in the new clematis hybrids that are reaching the market these years. Old clematis were hardy in zone 4, but crossing them to warmer growing one has yielded many new very desirable hybrids, but only hardy in zone 5, 6 or even 7. We have gained in beauty but lost in hardiness. In a word I don't think grafting would be successfull in the way you would want it to be. And breeding wouldn't work quite the way you would want either from what I understand from what you said. These are two of the reasons why I said that selection was a much better approach in your case. It is not an easier or shorter one way to do, only a safer one. Hope this helps!...See MoreFastest Growing Clematis (full sun, zone 3)?
Comments (12)I'd like to give this thread a little bump since I'm thinking about trying to grow Clematis here in Anchorage, Alaska. A lot of people grow the ugly species variety with the tiny white flowers here. But I'd like to take a stab at growing some show stoppers here in the Far North. I found a website that is claiming to sell some hardier varieties , and I'm wondering if anyone has tried the with success. Specifically, I'm interested in Polish Spirit, Perrin's pride and Avant Garde. The website is HummingbirdFarm. I'm technically in zone 3, but I think my microclimate is more like zone 4. Any thoughts?...See Morenorthspruce
