Would having magic involving plants be alright? I know that similar magic exists, but what I have in mind is a little different so I’d like to check just in case. 

It involves:
-growing plants & accelerating the growth of existing plants
-being able to sustain plants (possibly revive them? not on a big scale though, absolutely nothing bigger than maybe a bush)
-doing these has drawbacks, such as fatigue and having to keep the plants alive means needing to eat and drink more while they exist
-the drawbacks are increased depending on the size, type and amount of plants 
-they’re just regular plants, and don’t have any boosted properties, only those that they would have naturally

If you’d like any changes or extra details I’ll be happy to provide.
