Yeah it's marginal mate, best grown in wet and humid conditions rather than submersed.
Just to clarify on the name; 'albomarginata' refers to the white edges on the leaves. 'Albo' or alba' means white and 'marginata' means 'enclosed by a border' and always refers to patterning in taxonomy![]()
There may not be white on the one you have, but the species as a whole normally does.
It's bog plant so needs it's roots wet, but won't grow fully sumberged.
