What? No one has said "mallorn"?
I am a New Yorker, and I speak quickly for a New Yorker, apparently, so...I am probably way to fast to be an Ent...
Well, I went online to research trees (I'm weird, I know).
I was originally (before looking around) going to say "magnolia", but...now I think that I would be a Flowering Crabtree, a Flowering Dogtree or an Eastern Redbud. If I had to choose one...probably a Flowering Dogwood (a
Cornus florida) with pink flowers...
