Question about rootstock, hardiness and tolerances
Comments (14)Will, I think it's best to consider the needs of the roots and tops of the plant separately. The USDA zone rating is a rough geuss but as you know, with so many other factors coming into play as well (wind, wet soil, on and on...) Here's an interesting example from the same webpage you quoted from above: "Cedrus atlantica, brevifolia, and libani are all grafted onto Cedrus deodara, the least hardy of the three. There are several reasons for this choice. The hardiness is not a factor since the deodara root system in the ground is at least as hardy as any Cedrus cultivar above ground. Secondly, the root system is more fibrous and better developed than in the other species making it a much better choice for nursery use." In this example, the top is least hardy, but the roots are most hardy, and the species is the preferred understock. I geuss this all gets at your fourth question to illustrate that you cannot make a plant "more hardy" by choice of rootstock, unless the limiting factor is the hardiness of the roots (not the top) in the first place. I geuss others already made this point more concisely - just wanted to add my two cents and what I thought was an interesting and illuminating example.

Comments (5)I've been collecting for about 8 or 9 years... but yes Will you are right, I moved here in Sept 07 and on a late whim I moved (mid-December) 20 or so plants from my previous home and left the rest. There's 6.1 acres with that woodland at the bottom of the property and I don't know (maybe 1/12 or 1/20) is that woodland. I would think I will be able to add around 1000+ trees and shrubs total. I think I'm at 400 now. Tunilla - thank you. I have good soil elsewhere. I'm glad I asked, really glad! Glad you guys liked the photos. Thanks for the compliment about Picea abies 'Sherrie'. It's a gem and a gem of a lady. Dax...See MoreAbies cone ID

Comments (18)Hi Coniferjoy, "I see clearly the upright needle structure of A. procera involved in the photo's which Ken showed us" That uprightness is normal for Abies lasiocarpa; see e.g. , which is of a wild plant so definitely not a hybrid. The only difference of Ken's specimen is that it is a strongly glaucous-foliaged selection. "Beside this, there are also several crosses made by Kurt Wittboldt-Müller from Germany between A. lasiocarpa and A. koreana. This makes it clear that it is possible to cros these also when they are not closely related in the same section of the genus" A. lasiocarpa and A. koreana are closely related, both in sect. Balsamea. So this hybrid is no surprise. "A cross between A. lasiocarpa x A. koreana is called Abies x lasiokor. A cross between A. koreana x A. lasiocarpa is called Abies x koreocarpa" Sorry, no; all hybrids between any pair of species must bear the same name; which parent is male makes no difference. So at least one of those names must be a synonym. Whichever name was first validly published takes priority. See ICBN Art. H.4. BTW, has either of these names been validly published under the provisions of the ICBN? Resin...See Moreconiferjoy
