Banana Palm need some advice please?

A friend of mine has a banana palm. She says the leaves have all shredded but it has one large "flower" that recently popped out. But the flower looks unhealthy, somebody told her that the flower was a sign it was dying?
Does anybody have any advice on how to get it back healthy again?
Thank you.

 

If its flowering then the main stem will die and it wont produce anymore leaves.
Are there any side growths that can carry on?
The flower although not pretty is still strange, mine flowered last year and it took all summer to do it.

 

Hi pete2255
thanks for getting back to me. She says she can't spot any signs of new growth!

 

Well if there's no sign of suckers coming from around the base of the plant it is unusual.
That stem that is flowering I am certain will die afterwards, there is still a chance that it might put up a sucker or two yet.
Any ideas of the variety, I take it, it is growing outside in the garden.
