I actually just found what I think is a huge woodrose plant growing a block behind my local coffee shop hangout, growing up terraces around a door. I thought at the time I found it, it couldn't be, cuz there's no way it would tollerate the climate around here. (although it was the spitting image of the one I have growing indoors) Anyrate, I just visited the spot a couple of weeks ago and sure enough it had little woody seed pods full of seeds that look exactly like nervosa seeds. I got to em too late though to do an a more possative examination though, as the pods were all soaked from the unusual winter rain we are having around here.
