It occurred to me today that there comes a time when I just stop harvesting rust root due to it's frequent availability and my lack of use for it once I have solid ore supplies in hand. Rather than letting this forageable slip into obscurity as an ignored pop on the map, perhaps we can get some minor curiosity associated with it?
Maybe a Rusticle? (Yes yes, I know this has nothing to do with rust roots and only appears in deep water, but come on, the pun is there).
Just a minor thing, but it would keep harvesting rustroot relevant.
