new idea from nature: Rose Hips.

They seem like upward dune living species. Most plants in that region have some limited tolerance to saltwater, and even more limits to constant innundations, as they are FAR from tidal action and receive regular douses of freshwater in rainfall.

In addition, God help you if you need to get anywhere near the plant....those things are visciously thorny....prickers on every square inch..


Good luck though!

The freshwater need goes down to the roots, as does need for less than soggy conditions. That would be tough, as you'd have to have the substrate of substantila depth to keep it dry enough, and by then i think you would have effectively filled the planting space with sand completely. The only true plants commonly availible to the hobby (that are also effective in nitrate reduction) are mangroves (red, primarily, black for brackish, white used once i've seen, but long term progress not recorded) and marsh grass. Both can be kept submerged to a certain degree, perfect for a land-to-sea transition, and can tolerate the salinity and wetness.
 
there's many more plants out there that will tolerate brackish water. I'm noticing them all around me. in a bay in CT I saw moss growing inches from pure salt water... and several plants nearby that had roots that must be in the salt water 50% of the time. also, lemon bacopa is one I am about to try, which grows underwater and above... have it in fresh now, but going brackish soon

the aquarium trade is limited compared to what's in nature.
