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.
Absolutely gorgeous trees. I love it when they get a few mushrooms on them too. Just the glorious center of a beautiful ecosystem.
