Rose Vendors with R. fortuniana Rootstock?
Comments (25)Petalz, 'Fortuniana' normally does not make seeds, and even if it did, they'd likely not grow true-to-type, since it is not a true species. It also resents being bare-rooted and normally dies afterward. I know that we sent virus-free 'Fortuniana' to members of the Honolulu Rose Society, a decade or more ago. Do you know any of those folks? They may be able to supply cuttings within the state. Back to 'Marechal Niel' -- It has been suggested that much of it has a virus (likely NOT rose mosaic) which makes it difficult to grow. As far as I know, no one has ever proven that. But in any case, it does seem that some selections do better than others. We got ours from the plant Greg Grant and others found in Texas -- a very vigorous and carefree form. We then heat-treated it just in case. On 'Fortuniana', it is the most vigorous rose I've ever grown. We've distributed many of those plants, mainly at HRF meetings (Lakeland in 1991, Lakeland 2001, and El Cerrito 2002). ARE also has this form of the plant. So they're out there. Vintage also seems to have quite a good form of MN, but from a different (California) source....See MoreInteresting article on rootstocks for grafted roses
Comments (16)Maybe 12 years ago, I wrote the article linked below. The 3. at the end is a foornote to the 3 after susceptibility. George Mander "has made arrangements with a wholesale rosegrower, Jan Verschuren, to graft his budwood on R. canina. Jan prefers R. canina currently. R. canina is what was used there before WW2. The original canina was notorious for suckering. There are new canina selections since then. R. canina cv. "Inermis" is the most widely used variety. Much less suckering takes place, but it still suckers. R. canina cv."Heinsohn's Rekord" is regarded as the very best for Hybrid Teas (Jan agrees out of experience). R. corymbifera cv. "Laxa" or R. dumetorum cv. "Laxa" is more and more being grown on Europe's mainland. It was always used as a rootstock for Great Britain only. Because it suckers little and is, therefore, a cheaper way of growing roses, the mainland now also grows more and more on Laxa. However, Laxa is not as winterhardy as R. canina. For treeroses, R. canina cv. "Pfander" is the best one (his family has a well established R. canina cv."Pfander" weeping treerose of The Fairy in their garden at home surviving at some -24 degrees C unprotected, its budunion up in the air). Cheap fast production for big box stores has opened a market for multiflora cutting rootstocks for treeroses in Holland, but they have little winterhardiness. He also points out that R. multiflora is softer and the grafts a little more likely to be weak during the first year (Brad had one of George's Canadian White Star break right at the bud union; it can happen in a strong wind). Multiflora is much faster in production, but has a shorter lifespan than canina. Brad's experience is roses grafted on R. canina suckered freely and didn't produce as many basal shoots as R. multiflora or own-root roses. However, Jan points out that multiflora was shipped to Sweden because they had guaranteed snow cover in their winters. All other parts never wanted multiflora because of its frost susceptibility 3. Obviously, there is great debate going on here concerning the relative merits of various rootstocks." "3. This has always been a hot topic for Jan. Another former local grower here lost his crop on multiflora when temperatures went down to minus 24 degrees C. "I should have put more straw on" was his thinking... Jan hills up his budunions in fall and sleeps easy, even with minus 24. In his opinion, multiflora is never as winterhardy as R. canina selections are. As his father mentioned when he said to him that all growers use multiflora in Canada. " What?! Are they backward there?" The name Verschuren is closely related to rosegrowing in Holland. They are rootstock specialists. They produce seed, stratify and produce rootstock (about 6,000,000/ yr); and are only a medium size rootstock grower! Combined with Germany and the huge rosegrowers, competition is immense. Out of the competition, the best emerges because of the scale in which things are done there. The scales are different in Canada: here, rose production is done on a hobbyfarm basis. Multiflora is easy to grow; that is why it is used here; that is Jan's conclusion. When he met Otto Palleck, the just retired Ontario rosegrower, Palleck said, "What? You grow on canina? That is the best rootstock there is, but we cannot get No.1 quality here...." That was most likely not his only problem, as seed germination with canina requires 2 years of stratifying. Brian Minter told Jan initially when he started out doubtfully here with canina rootstock, "Do the best you can and grow the best product possible, and you will succeed" Now, Jan has customers who are coming back raving to buy more. His treeroses did not blink their eyes at the cold last winter." Here is a link that might be useful: A Visit with B.C. Rosemen...See Morenorthern pecan rootstocks
Comments (11)lucky p and olpea, thanks much for the response, i have several sources for rootstocks now. these are my favorite nut and i want to give them as best a chance to succeed as possible. n.pecans are being grown in the area but so far it appears as none are filling the nuts out.but the info is sketchy at best... cultivars are unknown,rootstocks unknown, elevation and microclimate unknown...etc.. i'm also sure it's a very small number of trees. the good news happens to be that the trees themselves are fine and doing well. even if they don't fruit they make nice shade trees. olpea i neglected to fill in the n.e.washington part of my post. i'm not too far south,canada is closer than spokane. i'm erring to a 5b zone,but 6a may be most accurate. am on a south slope and that may give me an additional edge when filling and ripening the nuts. here in the area there are just many micro-climates with huge differences on the same crops. peaches are the perfect example some get none...ever and there are those who get huge,sweet, branch breaking fruits every year. and i am testing my luck with a few of those. regards, wildlifeman...See MoreFire on firma rootstock
Comments (70)H.T., good to see you created an account here. Please post a pic of your A. spectabilis! Not sure I'll have room for a table mountain pine but that one is nice. One tree whose odor I've started to notice is my Chamaecyparis nootkatensis 'Green Arrow'. On the right kind of warm still day, you can easily smell it in that part of the garden. The same was true of my former A. concolor, although given the relative size advantage it had, I'd guess the cedar emits more volatiles per unit surface area. "Which now makes me wonder if I find firma, is it REALLY firma?" As I said, very easy to tell. Essentially no foliar odor, unless you practically snort them ;-) No one else has mentioned a scentless fir, and I've smelled every one I've met in person and they all have much more odor than A. firma, except maybe A. chensiensis but it is still easy to tell them apart. Actually, A. holophylla is pretty weak too, but still stronger than A. firma. (all 3 should make fine rootstocks for the mid-Atlantic/upper South)...See MoreKen (N.E.GA.mts) 7a/b
