I only saved a few stems, still got them packed away somewhere. It was back from my days of trying to grow 6 foot plus plants indoors. My intent was to try to fix them up and turn them into walking staves. I looked at them once about a year after I harvested them and decided that they probably wouldn't work so well for that purpose unless maybe I put a metal rod down the center of them. So I left them where they were figuring I'd come up with some other idea for them but so far nothing, and that was about 4 years ago.
