I feel like Rue's is more chemical than plant or growth, but chemical fertilizers are a thing.
Yes, this. I assume Rue's powers started as a plant growth sort of thing, but she adapted her powers into a "fertilizer bomb." (Which is a real thing. That terrorists use. Cube, WHY??!!) Rue's powers seem to me to be based around plant growth and alchemy (don't forget she also has healing potions), and the bomb throwing thing is just the most visible and flashy part of her kit.Rue's observed powers have more of a chemical theme than plant-based. But her name and colors, on the other hand...
