In one of Christopher Lloyds books he talks about putting them in a wet bit by a pond where they did very well.
In my dry soil they survive and flower a bit though not inmpressively. The bulbs are enormous eventually and resist efforts to remove them, coming back the next year even when damaged.
I think everything is better in the ground though I do have plants in pots sometimes
