What plants grow on rocks?

[MNfishy]

Ok so i have a 55 gallon tank with a bunch of lava rock, and im looking for plants that can grow in lava rock and that would be good for high PH water. And maybe 1 or 2 forground plants....

Both Java Fern and Java Moss will grow on rocks. Not sure what others will.

i think riccia will too, but it will be a pain in the a** to maintain

anubias would work i think.

anubias and java fern and moss can all also be planted in the substrate if you want, bury the roots but NOT the rhizome.
