Looks like Limnophila aromatica 'hippuroides'. That is what I have been calling it. The picture makes it a little hard for me to tell with the plants all bunched together. L. aromatica is a perennial herb and should have a mild sent. Submersed it forms a very atractive crown with light red to purple, non-hairy stem bearing leaves in worles of 3. Mine have lost most of there color due to low levels of CO2, based on my limited experience with aquatic weeds. Of course with CO2 they look more like this. The emersed form looks very different. After established, prune by cutting it back to get new, slow growth from the root stock and/or plant the cuttings for an immediate, beautiful, full sized crown. One of the reasons I like this plant.
There are number varieties of Rotalas and depending on light and lighting Rotala rotundifolia can have different hues, I have them from bright green to almost purple, all from the same starting bunch, acquired years ago. Rotala rotundifolia are a nice versatile plant that grows like crazy and people tend to ignore because it is plentiful and therefore cheap.
For those who like to brag about pearling plants and complain about having to trim constantly, Rotala rotundifolia is your plant.
Thanks guys, rotala rotundifolia it is. Sorry to constantly bring plant ID questions, but when my LFS can't even give me the right answer on plants they order, and I can call them on it (with zero experience other than their own suppliers website) I'd rather just ask people that do know. Thanks again.
You young ones with all your fancy new names... It's Papiliochromis ramirezi and Rotala indica I tell ya! We called it that way for years until some young person decided to change the name and confuse the heck out of us older people.
My LFS is the same csmith. There is this one employee that knows his stuff (and does most of the ordering). If I'm lucky enough, I can catch him when he's working, if not, all the plants in the tank are "some plant and will probably die in a few weeks anyway, so, who cares" according to the rest of the staff.
Biollante is right, this plant grows like crazy. I have to trim a stem or ten every week.
When grown submersed the leaves are narrow and pointed, when grown immersed, the leaves get round. The colors will vary quite a bit also. It's a nice plant imo.
