Lila, if you don't know, this plant should be in 'Stumpers'! You use the title 'Water plant'...does this mean that it was grown in water? Give us more info, if you have any...where you got this plant, etc.
Unfortunately I can't give you too much +info... :( It was a question in a hungarian plantID forum: http://forum.index.hu/Article/viewArticle?a=94110033&t=9110956 It was sold in a garden-center as a "water plant", (but of course this is not 100% sure, because they also don't know the correct name of this plant...), but I think it really looks like a water plant...
Hi Chris! Thank you for your idea, but I think this "salad" is bit more exotic and not a real salad... :)))
Yuhuhuu, I have brand new pics!!! :) Hm, and as far as I can see, there is a flower too (for Michael! :) I hope this helps... Thanks: Lila
An Alternanthera sp is my guess. http://thebegavalley.org.au/uploads/tx_steverplantgallery/Alternanthera_denticulata_01.jpg http://swbiodiversity.org/seinet/taxa/index.php?taxon=Alternanthera caracasana
