One stem with at least 5 leaves all submerged growth random pick (no ID). I do have various sized buces, so if you're looking for a particular sized buce, put it in the notes at check out I can fulfill if available. All buce has been propagated in my facility (keep wild buce wild-I do not promote wild harvested buce).
Buce is very similar to Anubias. It's an easy to grow low light plant. Buce does best attached to a surface such as driftwood or rock, glued or tied at the rhizome.
Buying buce already converted to submerged form saves you a lot of time, as buce generally takes quite a while to convert. Any piece you buy has already been in a tank for months and is growing submerse form leaves. They should continue growing well in your tank, given it has the proper parameters.
