yes, they can rot off if too wet and the drainage is not good enough or if you jut had a bad bulb to begin with.
Bulbs in pots are usually very reliable so worth trying again making sure you have a good bulb to start with and good drainage in the pot.
Anything you want to put in for some colour that will come up year after year will not look so good when not in flower so you are best to re-plant for fresh colour. Alternatively you could put in some evergreen flowering shrubs which will look good all year and give colour.
