8 years agoKen, I appreciate the advice. I understand the concept of estimated 10-year growth rates, and I also understand they continue to grow after ten years. :) I've also spent more time doing web searches than I really should. In any case, I was hoping to get a few responses from those who have been growing P. n. 'Frank' for several years and could offer their experience with it. Growth rate estimates are useful, but they are just that -- estimates.
I'm looking to screen an LP tank and need one additional columnar conifer to go along with three other conifers already in place. 'Frank' would fit the bill and I've found a local source for one. The key is that I want it to stay smaller than 'Arnold Sentinel', which can get up to 20' fairly quickly (see attached pic of tree at Denver Botanical Gardens). That would simply look out of scale for the site I've got.
BTW, sorry to hear about your troubles with P. nigra. Do you think it was the recent harsh winters that did them in? They're very cold hardy trees and it seems odd that a z4 winter would cause their demise

fall grafting
Comments (65)Hello all, Reviving an old thread here, but have a summer/fall grafting question. What are the possibilities for my doing some Abies grafting in August? The situation is that I'll be heading to the PNW in late July, and am hoping to take some scions at that time. I'd preserve them in a humid, cold bag until I get back to Indiana a week later, and then graft immediately. I understand that I might need to keep the grafts from freezing over the winter. Aside from that, does anyone think this plan has possibility? Thanks, JC...See MoreBluespruce53..... A Question
Comments (19)Thanks, bluespruce53 - I'm left slightly confused now. Staney & Sons description of P. n. 'Komet' indicates that it has 1.5" needles, half the size of your plant. It goes on to say that the leaves are lime green and that the growth rate is 2"-3" per year. The description just doesn't seem to match what I see in your photo, especially the long needle length and the deep green color (which, though, can be attributed to many things by the time the image gets to my monitor.) Stanley & Sons describes P. n. 'Arnold's Sentinel' as having very long needles. P. n. 'Frank' is described as having a dwarf, tight, columnar form, with a growth rate of 8" a year.

Comments (65)Abies lasiocarpa var. arizonica 'Glauca Nana' is a good one but it may become larger given time than say Abies concolor 'Archer's Dwarf' which makes a pyramidal shape sort of similar to Picea pungens 'Sester Dwarf'. About the red and yellow twig dogwoods. They form colonies with their roots and are better used for projects such as erosion control or on large properties where they are beneficial to nature. They are a burden, otherwise... and often do they succumb to leaf diseases. Substitutes for consideration might be hollies with persistent red-berries; Acer circinatum ‘Pacific Fire’; Hydrangea quercifolia; Regarding a smaller flowering tree, the problem with crabapples, again, are leaf diseases. I'd probably stay clear of those and use Stewartia pseudocamillia or another species. I won't mention it again, but Cornus officinalis is a great candidate. Dax...See Morehouses w/o lawns
Comments (29)While I will be the first to agree that a nice lawn of St. Augustine is a thing of beauty grass is still a high-maintenance ground cover, even if it is one that we have come to accept as the suburban standard. A lawn as we know it didn't become the "norm" until the Industrial Revolution when there was opportunity for the masses to copy the English aristocrats with their gardener-maintained swathes of grassy lawns showing they had the money and leisure to not have to plant every speck of ground in food crops. Until that time either a bare, packed-earth yard or a cottage garden was what homeowners had. See, I was paying attention in landscape classes. We have a lawn in the back for the dogs to play on but it isn't wall to wall grass, it's cottage-gardened as much as possible around the edges and the front is being planted with more and more native plants, grasses, and other drought-tolerant plants. We're lucky that we don't have an HOA nor is our code enforcement focused on this (yet). It's a difficult issue as so many people still do invest a lot of themselves in a "nice lawn" but the water problems are catching up with us and attitudes are hopefully changing....See Moreedlincoln
