Not a pregnant onion
I'm looking for help identifying a plant that looks a lot like a pregnant onion but isn't one. The bulb is green and rests mostly above the soil. The bulb looks like an onion but is about the size of a softball. Baby bulbs form around the base. The leaves are long and strap like.
So far, it sound like a pregnant onion but here is where it differs. It flowers directly out of the center of the onion. The flowers are large (about three inches) mostly white with a bit of lavender in the center. The flowers or not on a stock and look vaguely lily-like.
These are very old plants, maybe twenty years, but not woody. The stalk that grown out of the bulb is about two feet tall. The leaves fall away from the stal and can be two or three feet long.
I think it is either a relative of a pregnant onion ( we have one of those too) or some kind of amaryllis.
