AF Crypt. Costata - final size expectation?

[nry]

Picked up what I perhaps incorrectly thought was a small crypt, labelled 'Cryptocoryne Costata' which looks really small in the pot.

Is this going to grow a bit large long term?

AF (AquaDistri) list it as 10cm, is that I wonder the shipped size or final size? It looks very petite and it's been grown underwater for a while judging by the state of the rock wool!
