Slytherin for sure
Hufflepuff maybe? Maybe Ravenclaw? I say Raven.

: Hufflepuff, because you're very salt of the earth (erm, literally) and you like plants and nature so you excel at Herbology and are probably the professor's favourite student. Way to go! :)

you look like you have the makings of a good slytherin to me.
