Underwater vegetation on lush caves and more vegetation on its walls.

Lush caves are amazing, but ive noticed that deeper lakes generated on them have very few vegetation, small dripleaf and dripleaf generates only closer to the surface, so the bigger lakes dont fell lushy, im talking about adding underwater vegetation, on the bottom of them, not more dripleaves, and also, bigger lush caves feels much more baren, since vegetation tends to generate much much more on the ground and ceiling, and since they arent that big, maybe azalea bushes could also generate on the bigger caves just like jungle bushes are generated on jungles.
