Osoyoung, is that stewartia a bonsai or landscape tree? I got one last spring, and it's a pretty exciting tree to think about the future of. Your's has the type of coloration that I hope to see on mine. It's just started to turn a couple of leaves purple.
And rubrum, I always expect to see red leaves, so nice that you have a different version.
The Yellow hues of this plant reminded me of Scottish singer/songwriter Donovan's 1966 hit "Mellow Yellow"
This tree near work where I park is just phenomenal.Some kind of maple.
Ginkgo starting to show off...
