Actually, I am interested in the same question. The answer I have found so far is NO- cuttings only. But, don't ask me where I found it- I don't remember.

Actually, I just googled dividing integrifolia, and it seems that it can be done. It's supposed to be done in autumn. If you try it, don't forget to post the results. I'll try to take cuttings, and will post the results as well.

Here is a link that might be useful: google results

Anxious to hear how this turns out. Sounds exciting. Would be a way to have more Integrifolias spread through the beds.

that's what i've found out, by googling it. IF i do it, i will report next spring.
best, mindy

I've divided integrifolias twice. One was about 6' to 8' across. It did not divide well, I lost all but one piece. I divided Alionushka because I had to move it out of a large barrel. Out of 5 or 6 chunks three pieces made it. May I suggest - if you don't need to move the clump completely but want starts just dig in one side that sticks out and cut a section off (with roots) and pot it up for TLC for a year. I've done that with lots of my clematis. I get quite a few root starts that way.

or did you mean inches? mine is 12"diameter clump. did you mean use the shovel to dig up one side of the clump and cut away a section with roots?

if i were to pot it up for a year, that would have to be inside in the winter here in z.5, so i think i'd have to plant it immed'ly after dividing.
