"Welcome to the Greenhouses first years. This is where we keep and grow all the magical plants at Hogwarts. Some greenhouses have more dangerous plants, so we'll keep to the more mundane plants for now. So...who knows why plants are even important? What do they matter? ...and why have a class at Hogwarts all about magical plants? What do we do with them, and how do we care for them? Any thoughts?"
"This session we'll be working on an improved fire spell. So first, why would we need fire spells specifically in Herbology? How can we best use this spell...can you think of any situations? Does anyone happen to know the incantation?"
