I can vouch for the layering method of routing on these hydrangeas as mine has rooted wherever stems have touched the ground (mulch, actually). This is an excellent method of increasing your stock of h. PeeGee!

Mom had one that layered itself, and that's where the 2 I have came from.

I'm spreading these around my property also. I need to see if oakleaf hydrangea will root as easily. Do you know?

Well, I was helping a friend clean up in her landscape last year, and we found that one of her oak leaved Hydrangeas had indeed layered itself. The stems are more stiff and upright, so it may take some good weight to keep it in contact with the soil, but it definitely should work.

I'll give it a go!
