Growing clematis from seed

On an earlier thread I mentioned germinating clematis seed in zippy freezer bags using wet vermiculite, several people have e-mailed me since, so here goes.
Using a 5 or 6 inch square zippy freezer bag, add a handful of wet medium grade vermiculite, put the seeds in, shake the bag and seal with the zip.
Put the bag in a warm place, out of direct sun and do not unzip the bag, keep the constant humidity.
I took a couple of pictures of some texensis seeds, extremely rare and notoriously difficult to germinate, but well worth the effort.
Here you can see the seeds have germinated in the vermiculite.
I have also used this method with other plants including lilium

Thank you Richard

Richard, thanks for that. Can all clematis seeds be germinated in that way? I've got C. alpina columbine white which seems to have died on me , but still has seeds on it. Might it be worth a go?
My friend Lyn took some , no doubt hers will be in flower before mine get going.
Yes, all will germinate using the bag method, some are very quick to germinate, tanguticas are easy, some take time.
Your alpine may not be showing new growth yet, most of the atragene group, koreanas, macropetalas, alpinas look dead at present.
Richard, I wish it were so, but it seemed to give up the ghost last summer. It was in a largish pot in an unheated polytunnel awaiting a place in the garden and it just seemed to give up. A tug pulled the topgrowth clean out of the pot.
I don't suppose there's any chance of regrowth from below soil? I know from experience they can shoot even after a 3 year no show.
Would Perlite do or must it be Vermiculite Richard.
that's it Richard, flood gates open time.
I also sow lots in pots, these clematis campaniflora were sown in John Innes Seed Compost 23 September 2015.
Are you insinuating something Hosta?
tee hee . I know you and your seeds Lyn. x
These are the clematis that the ' anoraks ' of the clematis world would kill for, all reliably hardy, superb unusual garden gems, have a look at this site.
