What plant is this

[willsFishTank]

I got this plant at a pet store and it was in a tank with a lot of other plants and the guy told me it was horn wort but it wasn't so I don't know what kind of plant it is. Here's a pic



P.s. it grows on a single stem with leaves coming off it

It's definitely not hornwort. I am not sure it is truly aquatic.

Oh we'll hopefully some one else knows what is it

Looks like it might be emersed growth wisteria.
