Plant influences

These are my thought processes behind the intelligent plant-forms that I am thinking about.

1. Through hiding brains and other body parts in his garden a humanoid plant is born which can manipulate the other plants in the garden much like Poison Ivy from the Batman series.
2. Trees turning into giant beings such as Treebeard the Ent from Lord of the Rings
3. Simple plant designs more of a cute option inspired from Plants vs. Zombies
4. Horrible creepy trees like that of snow white accompanied by similar sinister plants 
5. Another cute cartoony option inspired by Piranha Plants from the Mario series
6. Horrific inspiration from the plant-like Las Plagas zombies from Resident Evil 5
