Can you try to identify this plant please

I rescued this plant some years ago from a ex-plant warehouse. It was marked as a banana...but sure its not..its never flowered & leaves grow of varying sizes...any ideas? I`ve been trying to find out for ages...so I know its best conditions, as occasionally its leaves go yellow & droop, which I remove.

looks like Elephant Ear - common name. Tropical, likes shade, likes to be crowded in with other tropicals for humidity. Yours is in a pot - each time you enlarge the pot the top will grow much larger. Leaf size is by age - small = younger, large = older leaf. Older leaves naturally grow yellow and drop - it is OK to cut off yellow leaves. Some flower, but many do not.
