Hey guys, I was wondering what terrestrial Utricularia (or even Genlisea) can grow under water, permanently? I know that U. graminifolia can grow submersed permanently and it is now a popular aquarium plant!
Can anyone give me any info on utrics that grow well under water? I am not looking for aquatic utricularia that can grow attached and grow as rheophytes, like U. volubilis (IIRC), but I am looking for terrestrial utricularia that are usually grown in pots with media, but can when totally submersed in water.
I do not mean utrics that can tolerate occasional flooding and temporary submersion, but rather utrics that can grow under water permanently.
Here is a picture of U. graminifolia growing underwater in nutrient-rich substrate. It grows REALLY fast!
As you can see, the submerged photosynthetic stolons are totally different than the emersed photosynthetic stolons. It's elongated and sort of waves with the current like a field of wheat.
