For questions related to plants and vegetation in general.
From Wikipedia:
Flora is the plant life occurring in a particular region or time, generally the naturally occurring or indigenous—native plant life. The corresponding term for animal life is fauna. Flora, fauna and other forms of life such as fungi are collectively referred to as biota.
Questions on flora can be focused on fictional plant-life or the specific use thereof, or on conditions created by the existence of particular genera.
