I think I have mistakenly bought a non-aquatic plant.

Can any experts check whether the red plant below is Alternanthera Sessilis?

I bought it at a LFS tied up in a plastic bag full of water, hence I thought it was submerged. At first I thought it was Ludwigia, then Alternanthera Reineckii, but then currently I suspect it is Alternanthera Sessilis which is non-aquatic.

Cost is only $2, hence monetary loss is small, but if it is confirmed non-aquatic I would pull it out of the tank as soon as possible.

Thanks a lot!
