It transpires that certain types of sumac are poisonous, possibly including the one I find here. It is not used in a culinary manner here, but in TCM (Traditional Chinese Medicine).
I have removed it until I can confirm its edibility or lack of such. With it being the start of the two-week long Chinese Spring Festival tonight, that process may take a while.
If it helps, sumac is often poisonous here as well.
Edit: it is pretty though.
