It really looks like a young alocasia, but if it is, I have no idea which it would be!
The leaf shape is an elongated heart, like odora when very small, but it doesn't strike me as odora.
The real kicker is the petioles!
They ate very evenly covered with green vertical dashes... Against an almost white background.
A Mac. Variegated had streaks of white on green pets, Okinawa silver had more white vertical stripes than variegated. These are distinct dashes, equal length, and even spaced and distributed...
I'm at a lose!
I'm afraid it's another genus, possibly a giant calla, I'm just not sure of much about it other than its an aroid that makes tubers...
I hope the pics look better on full screens than they do on my 3" screen, the dashes are very noticeable in real life.
It's growing well, but seems sensitive to hot direct sun for extended time, as if it were variegated, but the leaves are solid light green with lighter veins...
Any suggestions are welcome, I'm a bit at a loss here. So many plants have popped up in collection this year, colocasias, alocasia, bananas... Other random stuff, but I can roughly ID them, I just don't know where they came from... This one, no id, no source...
Thank you folks!
