Minerva was taking notes on everything he was saying. She might not be pursuing a career in Wandlore, but she couldn't help but find it really interesting, but when was learning not interesting. So it seemed she was a bit off on her answer, but it didn't matter she wasn't an expert so all she could do was give her best guess.

She couldn't help but roll her eyes a bit when the talking to trees and sacrificing for them got brought up. She always thought they were all insane for doing that last term, but would have never said it in front of Ethan. She hoped for the love of Merlin they wouldn't have to do that. Maybe this guy was sane enough to know it was a tree, it would be fine with bark being taken.

Putting up her hand she decided to talk about Rowan, "Sir the Rowan is also called Mountain Ash, because it's a smaller tree or shrub. It is said that the Rowan has a dissociation with the dark arts." She loved when her library trips came in handy well that and her boyfriend was a plant lover.
