Add a ton of rain and clouds to that and we have a cool look in the extended.
What about something with some showy flowers in the spring? Like a redbud or dogwood?
A tulip tree grown in a more open space would probably get a lot more wide/full than you experience in the forest where all of the trees are trying to outrace the others to light. Those will put out beautiful flowers after a decade or so of age. They have unique beautiful leaves too.
Is there any particular look you were going for?
