Having plants indoors makes the air more oxygen-y and can make a room less clinical and more cozy. But taking care of living things can be a pain! Other than just throwing some cut flowers in a vase, here's some neat ideas for adding a bit of green, alive or not:
put some fuzzy moss in a clear glass, a bell jar works nicely too (but it will die without a breathing hole)
nail some drawers to a wall and plant some ivy (or cut some faux ivy out of green paper)
This tree design was made with string and tacks, i like how it bends onto the ceiling. I think it could be complemented well with a mounted dear head or owl plaque under a branch, IDK
