This is somewhat interesting.... I have a plant that is clearly Utricularia praelonga but it is not producing the characteristic grass like leaves. I am unsure if it is a different clone or if this is due to the use of a different brand of peat. I also attached a pic of my other 2 pots of Utricularia praelonga.
I apologise for that bad pics, took them in the dark with a camera phone.
