ID this "tree"

[AnonYMouse]

I recently acquired a bare bonsai "tree" and it is mislabeled. The tag says, "winter something something in Japanese Cornus". Now that it's blooming, I know it isn't a Cornus (Dogwood) and since I know squat about trees and shrubs (with few exceptions) I'm asking for help identifying it. Doesn't have foliage so it may not be possible until spring. Worth a try with the flowers.




TIA, Anon
