Our Clematis Club has this interesting group as the Clematis of the Year 2006. I'm now trying to make a short presentation for our club-journal about the most important of the species.
This way I have understood the key characteristics from the books:
The table shows which of the species have glaucous leaves and which net-veined.

Timo, a very idea. It is such a difficult group and the problem is that a lot of plants in the hobby are not the right species. My experience is that a species cross very easy with an other species.

I also agree that a number of the species plants we find in Europe are not true to type, for example glaucophylla and reticulata, and I have been fooled in this respect myself in the not too distant past.
The fact is that with a number of the species having such a large range, it means that they can vary quite considerably while still having all the acceptable attributes of the species.
I am trying hard, whenever I can to grow and if possible distribute plants grown from wild collected seed, but this is no easy task, as seed from too many of the different species is commercially unobtainable, and we have to rely on helpful amateurs like ourselves, who also happen to live in or visit the areas where they grow in the wild. I am always delighted and grateful for wild collected seed in particular, and do my best to spread the seedlings, and seed when I am given more than enough, about where I know it is useful, and valued.

From these discussions I already had made the conclusion, that the seeds from gardens are hybrids, maybe in several generations. But they give nice seedlings, and most of us are happy with them.
I wish to avoid too many words for the botanical details, so I made the table.
Now I ask you if I can use some of your images which I have collected from here. Suzy's C. glaucophylla, Marie's C. pitcheri, Ton's and Brian's C. texensis, ...

Timo, as you know you can use my pictures. I have a lot of this group but not sure species such as texensis several, addisonii, glaucophylla, versicolor, crispa several, viorna, pitcheri etc

Hello every one
I agree with Ton san, also Keith san's opinion, but I am pleasing of their beauty perhaps same to Timo san.
In Japan. they also troubling with the commercial seeds which mostly contaminated by the species closed to, if they want to have pure species.
In my case, if I got wild collected species clematis I usually keep its clone by taking cuttings or root grafting.
The species clematis in North American continent are seemed to easy to cross each other, but I wonder even graucophylla would cross!
In my procedure the pure texensis is very difficult in taking cuttings. But it could be possible by root grafting when I use the underground sprout as scion to graft to texensis own or viorna root. There are some surplus underground sprouts when the texensis grows old.
Someone in Japan indicated me he could succeed in texensis propagation by take cuttings by using young scions and the survival rate was about 70% so long as I have heard. But the details are still unknown.
Are there any idea for this?

Thanks for the comments and photos (more about them later).
Now I should write a few words about mildew.
C. texensis and its hybrids are said to suffer from it. You who grow different Viorna group varieties, could you please tell which species are most prone to it, and which maybe are free from it?

Hello Timo, I have sent you an e-mail about the picture.
I have had powdery mildew on my c. Glaucophylla every summer, but I have learned to spray a Rose fungicide beginning early in the summer and continuing treatments until autumn. This works well.
Of my Texensis cross hybrids, I have never once seen any mildew on my Duchess of Albany and I have had no need to treat this plant with any fungicide. This is a strong and resistant hybrid, apparently.
Gravetye Beauty has had a few mildew problems here. I now use rose fungicide on this plant beginning in early spring before mildew begins. This has worked well.
Good luck with your presentation !

'Duchess of Albany' is definitely the strongest and most mildew free, once it gets established, followed by 'Princess Diana', then 'Gravetye Beauty', then 'Sir Trevor Lawrence' and lastly 'Lady Bird Johnson'. Sadly I don't yet know about the new ones from Barry Fretwell, as you in the USA will get to buy them before we can over here, which seems a bit crass, when they were bred only a hundred miles from where I live as the crow flies! I did try to get them, but no luck, even before Barry retired. I am more sad to have missed out on 'Cascade', as I suspect that the other ones of his will eventually get back to here, but 'Cascade' might have too much of a niche market to tempt the large exporters.

Timo, I have no mildew in my several 'texensis species' and viorna. In all the other, depending of our summer, have more or less mildew.

Takeuchi San,
To root cuttings of the species texensis is reputedly very difficult, if not impossible, and even its hybrids are very difficult for me. Brian Collingwood has been successful, and has explained his methods here in this forum, using underground sprouts. But it does not seem to work for me.
Apparently, it is just a matter of knowing exactly the right method and exactly the right conditions (time, temperature, light, humidity, etc.) I know a Dutch professional nurseryman who grows the species texensis from cuttings (young scions), without problems. I do not know exactly why he succeeds and others do not. I think most nurserymen keep their own little secrets to avoid competition.
By the way, has the seed arrived yet?

Now our club journal 1 / 2006 is ready. I have written something about section Viorna species. Many thanks to all who have helped me and given so many fine clematis pictures! The only color page is the cover, which is too small for all photos. Several more are placed on black-and-white pages.
Time to start with nr. 2 / 2006. There I will continue with the cultivars from Viorna and Texensis groups. I have already some photos for this part, but hope to get some more.

Roger san
I haven't been here for the long time and did not noticed Roger san calling. I am sorry.
As for the root grafting of species texensis, under ground sprout to viorna root was my only one successful actual result. When the texensis in the pot grown up to old, I could get two feeble sprouts which would be grow to flowerless vines. I use it as it was without dividing. The scion is 2~2.5cm, fresh and juicy.
The number I tested was 2, but all hit.
It is not good method for propagation because we can get very small number of scions in chance.
In Japan, one grower succeeded in 70% hitting ratio by taking cuttings. He said that he used younger scions. But sorry to say I did not heard what gnat he has. As the texensis vine usually has side sprout only a few nods from the ground on the thick vine, I suppose he would take sciones from the thin vines of younger plants(?? )
The seed has arrived already.
Thank you very much as to gave me such a precious seed.

Thanks for the kind words. The red clematis is Brian's. At least Steve, Suzy and Keith may also recognize their photos.
Our club is theoretically bi-lingual (Finnish and Swedish), but because all of us speak Finnish, Swedish language is not used often. Only sometimes (not every year) we have short texts in Swedish in the journal.
Bengt, the journal will be posted to-day!

Thanks Timo
It may be of interest to the forum that I will be unable to read the Finnish texts. Finnish and Swedish are completely different languages, Swedish being related to other European languages. Finnish is only related to Estonian, and some say Hungarian but this is perhaps only remotely. Timo often translates his work for use in the SClS Journal and we can see the size and general content in the Finnish version.
