The tannin stained water will cut out alot of light, so low light plants would be more suitable for black water tank setups... can try anubias, java ferns or java moss (or other similar low demand plants).
Floating plants like frogbits would work too, they can utilize all the light available since they are at the water surface and are very effective in soaking up nitrates.
Most black water habitats (and tank setups) don't have much plants anyways, usually just lots of branches and leaf litter.
