I think I'm legally obligated to say oak on account of being a dryad. I like those massive redwoods, and cherry blossoms are pretty but the fact that the cherries are inedible is just kind of fucked up.
On that note I think I'd have to go with plum trees for the fruits. I like pines just cause their needles smell good.
i was going to say oak. specifically shumard oak, for all it's resilience and all the services it provides to its neighbors. but i have to admit ginkgos always make me turn my head. the leaf print / profile is enchanting and it's hard to overstate the living fossil thing. trees in general are a window to the past, but the ginko is like a magic portal to another reality.
