Yes. “Bac ha” in Vietnamese - sometimes called elephant ears and sometimes called taro stems. However, they are a different species than the taro grown for the starchy roots.
" Colocasia gigantea is close to Alocasia macrorrhizos and is thought to be produced from natural crossing between A. macrorrhizos and C. esculenta"
I found this part interesting as the stems of both those other plants are NOT edible without pre-treatment to remove oxalates and saponins.
