Add Lush Cave Plants to Dark Forests

Dark (or Roofed) forests seem like a perfect place to find occasional spore blossoms, glow vines, moss, and azalea bushes, as their thick canopies block a lot of natural light, and can give them an almost cave-like atmosphere at times. So perhaps rarely, a dark forest might spawn with some lush cave plants inside, maybe hinting at the presence of a lush cave below.
