Lori,
I
was asking about habit. My understanding of the "shrubby" Clematis is that they maintain a permanent system of stems/trunks, not being a climber as such. That is why I was asking whether yours was a shrubby one or not. You've answered me perfectly, as yours is one of the herbaceous types that die back to the ground. The flowers on yours are similar to my stans in many ways I think, which was why I was wondering whether yours was another of the shrubby types. I have no idea how many shrubby ones there actually are, so it was worthwhile asking.
I get moderate seeding from stans (probably mainly because i trim it back after each flowering and it comes back into flower again throughout summer) and a few seedlings coming up. A Clematis I wouldn't be without now, but I don't think it is one that commonly seen as I rarely see it mentioned.... or else it is so common that no-one thinks about it.
