Thank-you Jay, Laurie and Kat for your help! It seems that my successes are correlated well with the "weediness" factor. In other words, plants that grow fast in general, and are well represented in this area, such as Solidago, Agrimony, Hydrangea (native) etc have done well but things that seem to be slower to spread (at least around here) did not make it. My biggest failure was milkweed...I really wanted to see some Asclepias amplexicaulis but all the cuttings died....maybe as Kat said it was the wrong time to clip? I think next year I'll do some experimenting with common milkweed....maybe that'll give me some indication of when to clip. I've just taken some river birch, Calycanthus, Hamamelis and Clethra cuttings....these things all had new growth from the excess rain we've been having...I'm assuming that new growth is a good time to clip
