Exclusive jungle plants (lianas and maybe flowers)

First of all jungles could receive lianas as a new type of common foliage that could generate like bushes in forests and temperate biomes. They could also receive a handful of exclusive flowers like the bromelia, heliconia, or poinsettia. They could also just be given some different colored orchids or something like the passion flower which could come in a couple different color variants to help further make this biome a little more unique.
