I've grown this for many years. Quick move it outside, down your cellar, to a room you can close off, when that flower opens it will smell like rotten chicken left outside in the sun for a few days. The smell will leave the beautiful large flower after a few days but believe me the smell is awful. I've taken mine out of the pot and now grow it outside where it blooms in late April and the air takes away the awful small. I'm enclosing a picture of my flower if this is yours get ready for an unforgettable experience. This is Amorphophallus konjac.
