Bass,
Have you never rooted "green" cuttings? Last year I did for the first time. I had my doubts, but Leon assured me they rooted easily. I cut about a dozen cuttings in May (with full sized leaves). I sent five of them to Leon, and I rooted the rest. Both Leon and I were 100% with rooting these cuttings. I think Leon has stable plants from all five of those cuttings. I lost one or two of mine after they rooted, but the the ones I have left (I traded a couple of them) are stable plants now that have already leafed out this year.
