Any changes to this long list of fragrant roses?
Comments (20)You're welcome! It's not odd that cooler zones will report more fragrance from many than warmer areas. Those in the cooler places are probably smelling them when the oils and alcohols are most volatile and smell the most. We in the warmer areas often miss out because they evaporate faster as the heat increases. Also, as aridity increases, the scents burn out faster. The various components of each rose's fragrance evaporate at different rates, so one may smell very Damask at first, quickly morphing into orris or citrus, finishing a completely different scent before losing any detectable trace for the day.

Comments (57)mad_gallica -- 'Rose de Rescht' is available clean, but not due to our heat therapy. We got it from Heirloom, who apparently imported a clean one from Europe. We indexed it here and found it clean. true-blue -- I've heard people make claims for resistance to fungal diseases and other "miracle cures," but I have no reason to believe any of them. Removing the viruses that cause mosaic will alleviate any symptoms those viruses may cause, which may include fewer, smaller flowers, shorter stems, less longevity, less cold-hardiness, etc. And in at least some varieties that are said to have "declined," it seems to help reverse that. But no, I'm not aware of (nor would I expect) other major benefits. I'm sure by "indexing," you mean the heat therapy process. Actually, indexing follows therapy -- it is the series of tests done to demonstrate freedom from the viruses, after we've removed them....See Morered oak vs. swamp white oak
Comments (32)I planted a swamp white oak 18 months ago. Was just under 5' tall container, mail order from Forest Farm. I had read that swamp whites are slow growers, but mine has been very vigorous. I think buying small is a good strategy because the 10' B&B's at the garden centers will stare at your for a couple years before taking off and require a lot more watering. This guy will catch up with the bigger ones. I just watered mine weekly during the first summer, but did not water at all the second year. Generously mulched w/ leaf compost. Grew like crazy. I had to re-establish the central leader due to heavy deer browsing. After protecting, it easily put on 2-3 feet in height and a ton of density in the second summer. The trunk really bulked up quickly too. Looks like a winner. Fall color is better than expected, kind of a pale orange. In an area like NE Ohio, which is often pretty wet but also goes through some dry spells, swamp whites seem to thrive. Unlike a lot of oaks, they can supposedly handle wet or dry. Northern reds seem to prefer somewhat drier sites. Of course, Northern Reds are still very good trees. If you are dealing with wetness and/or clay soils, an alternative is the Nuttalli. They have the best form of the reds from what I have seen around here and are starting to gain traction. Guy Sternberg developed a nice cultivar (New Madrid) that you can buy mail-order. Just got one of those too....See MoreNorth American vs European rose hybridisers
Comments (50)I had a point somewhere when I started that thread on this subject which I can't find now. So I'll settle on Cactus Joe's thread. Anyway I came across an article on Kordes in my old Rosebank news letters. It was an article by Harry McGee in September, 1995. The occasion was a visit to Canada by Wilhelm III. It has a good history of the Kordes firm. It started with Wilhelm the first in 1890 in Hamburg. Wilhelm II joined in 1919 in Sparrieshoop. He was succeeded by a non-Wilhelm but still a Kordes, Reimer. Then came the III. All were in charge of breeding operations. Other family members ran the business side. What is relevant in all of this is that the hybridizer was preminent in the firm and therefore put emphasis on that. At that time Kordes was the largest rose nursery in the world selling 2 million roses a year. They made 50,000 crosses a year. After a rose is singled out as a prospect it is grown for 6 or 7 years of testing before it is introduced. They probably are still the largest. Possibly the odds of creating a superior rose are in favor of those who do the most crosses. Stands to reason doesn't it? Even just blind choice should produce now and then something of value. One thing Mr. Kordes said that was interesting is that many breeders have stopped breeding HT's. One reason is that fewer people go to exhibitions. The other is that they are more difficult to get anything worthwhile. Hard to make disease resistant, many are single, fragrance is rare, have fewer hips and what they have don't germinate well and finally they produce fewer flowers. The emphasis on disease resistance began as a result of the Green Parties efforts to ban spraying in many parts of Germany. Kordes then stopped spraying. The result was disaster. Their fields became nearly barren of roses. I guess things have improved since then....See More- 7 years ago
