Sounds like the verdict is unanimous; it's Pinellia pedatisecta. And it i=s invasive, popping up everywhere. Very much outdoing our native A. triph=yllum. Thanks for the warning. I've got to get rid of it. So this is the =same as "green dragon"?
Wonder if this is on the USDA's list of undesireables. We certainly would=n't want it in our seedEx.

I'll second David's comments, and also add P. ternata and P. tripartita=to the list, as well as almost all the rest of the genus.
P. cordata has such attractive foliage that I do let it spread a bit (w=hich it does by bulbils, always scary). So far it's stayed in one area.
The only "safe" Pinellia is P. 'Polly Spout', a hybrid between P. pedat=isecta and P. tripartita 'Atropurpurea' created by Dick Weaver of WeDu Nu=rsery a few years back. It combines the attractive properties of both par=ents and is STERILE!
