No, it's definitely a Sagittaria species, Philip! That's my fault...I should have taken a picture of it before I had planted it. It does look like it could be Lilaeopsis chinensis from that angle. Sorry about that!
ADA-- not sure why you think "swamp thing"!
but, why not? There is a ton of Spanish moss hanging down for the branches, the water is tannin stained, lots of crypts.....seems like a reasonable comparison! I think that the addition of some IAL's would have been a nice touch.
