cordyline stems

i have a cordlyine which i have had for a year, it has suddelny grown a large stalk like stem, which looks to have small seedlings on it. i dont know wether i should cut these off or continue to let them grow.

 

Its up to you really. how tall is it? Is it green leaved or coloured?
Suddenly you say, could this be a flower stem maybe? If its sprung up all of a sudden I reckon it could be.
