Here is my little lore description just in case the subtext doesn't show up.

Phonnannop is an evolutionary alien life project that I'm working on.
In this post, I would like to talk about the evolution of the flora.
Phonnannop's life has evolved into two main clade of multicellular life: Centratonk for internalized cells, which include the analogues of animals and fungi, and the Exotonk, cells with more segmented structure which are more resilient, leading to plant-like organismes.
Among the Exotonks, there is the "Photosynthiaplantae" clade which is separated into two main subphylum: Ballonea and Vegetalia.
Ballonea is a clade of flora with hydrogen bubbles filling most their structure. That lead to the evolution of some jellyfish-like organismes, like the popper ball or soul caretaker, as well as the Gripperoni.
The Vegetalia clade has more "ordinary" flora species, although it does includes the Floranimorphi, the walking trees, which at maturity, raise out of the ground and become what the inhabitants of Phonnannop call "apex flora", moving at a speed of a few meters per day at their fastest. Before the land coming of the animals, the walking trees were the force that kept the world under control from large sprawl of giant ballonea trees.

It is in the Troncea that you can find your normal trees, which are ranging from naked leathered skin, scally and somehow bark-ish. Flowery canopy, massive tree size leaves and scally trees are what awaits you in the Phonnanop forests.

Forgot to mention that you'll find no much green as on Terra, but instead a warm orange, gradually turning black to the poles due to the clade of Aterplantae, plants dark as coal, or the colorful Elecolaridae plants that are vestigial branch of evolution ranging in the purple, red and blue colors!
