This popped up in the past two weeks in a part of our nursery area where I've planted various aroids (arisaemas and pinellias) in the past, as well as various other shade-loving plants. Most don't survive, so I lose track of what's what, and I don't recall seeing this one before. I think it may be an arisaema. What do you think?

Arisaema consanguineum or A. taiwanese? Whatever it turns out to be, if you are tired of killing it, stick it in the mail to me.

Arisaema consanguineum looks close.

Hmm, looks like a reasonable fit from the online photos I've found. I did try to grow A. consanguineum some years ago, but according to my records I stuck it in a different part of the nursery area (and never saw them again). Hopefully this one will be big enough to flower next year, so I can tell for sure.
Thanks!
