Wow. I had ordered from That Fish Place and they gave a bad online order experience. After paying for stuff they contacted a few days that they don't actually have half of it even though website showed in stock (and had me pay for it). Told them to send what parts of the order they had and I think they willy nilly sent me whatever they wanted. They sent miscounts of items, missing some, and got one thing I didn't order. So I presume in that mess of an order they mislabeled this as Rotala H'ra Vietnam.
The shorter red plant in front of it is some "super red" Ludwigia I recently got (elsewhere). The leaves are different shape. Is all Ludwigia "Super Red" the same as "Palustris"?
I don't know the origin of the 'super red' but it's not the same thing as the palustris you might find along ponds and wet places in much of the US. The latter is a bit bigger and more of a peach color.
