Vietnamese Taro Stem
The label said galadium where they probably mean caladium.
However, I don't think anybody eats caladium stems.
Another name for caladium is elephant ear, but there are 3 others species with the same name!
* alocasia (bac ha)
* colocasia (taro)
My guess is that this is alocasia aka bạc hà. Not colocasia aka taro stem.
