I assume you know that there really is a Hygro called "sunset", and you
mean that the Alternanthera came in by mistake instead?

That is my understanding for this plant as well.

Remember, though, that R. macrandra really _does_ grow happily under water,
even in the wild.

The only Alternanthera that I've worked with was A. reineckii, and that
plant could be grown just like R. macrandra in my moderately hard water...
Lots of light, supplemental CO2, and potted with soil and some laterite or
micronized iron.
