Yes, I pretty much ruled out the cucumber early on inspite of there being some similarities. Like you said, tree form was off as well as the bark. I had no idea about the color of the flowers at the time I was considering it, the one bud with color just appeared this morning, so I'm glad that's another confirmation that it's not a cucumber. And the pink/white flowers on magnolias are my favorite. At least it's looking like I'll get to see a full flower soon and not have to wait until spring. And yes, I realize the individual flowers aren't much, it's the total package that's so "ooooooooooh!"
