Dwarf banana not growing in height

[LittleDreamer]

Hej guys,

I have a banana three that seems very healthy. It is releasing new leaves every week, it has few pups and leaves look healthy and green. However, it is not growing in height. Does anyone know what could be the cause of this?
Thank you in advance!

Maybe it`s because it is dwarf

I read that their usual height is around 2 m and mine is around 15-20 cm tall :/

You have given no indication where you are in the world - if for example you are here in the UK there will be very little chance of your banana or any other indoor plant putting on a growth spurt until the temperatures warm up a bit. Everything slows down during the winter months.
This plant requires lots of humidity, heat, light and water during the summer months and would do very nicely in a hot house.
