Any idea what this is? I grew this from NARGS seedex seed in 2012 as Saussurea nepalensis... which it clearly is not. The seedlings already looked "off" in the early days, compared to those grown by others here (and also by myself on a previous occasion). This year, I was bemused to see it send up an upright stem that has now topped out at ~1m (39"). Until these yellow flowers started opening, I could have perhaps continued to think it might be some sort of not-rock-garden-material Saussurea but my credulity is all used up now, LOL!
So, before I yank the last one out... it would be nice to put a name to it. Thanks in advance for any suggestions.
