I have some growing emersed, but i almost killed it off with the low and angry Norwegian sun this summer. Its recovering but not as big yet as it was.This might be a silly question, but has any-one grown Ammania (Nesaea) pedicatella emersed?
Then you could play with nutrient ratios without having to take CO2 into account. I'm guessing that it will be a lot happier emersed <"and may flower">, which would help with naming as well.
It may come as a surprise to forum goers no doubt, but i am in fact even worse at keeping terrestrial plants than i am at keeping aquatic ones 😉
It doesn't seem fussy emersed, growing fine in some tropica soil. Not sure i have the motivation to play with the nutrients though
