I tried to look up what these plants were, because honestly, I had no idea.
I found out that the plant in the first photo is called Buttonbush (Cephalanthus occidentalis).
The second one, although pretty nifty looking, eluded all of my attempts at finding out what it was. The leaves on the plant reminded me of magnolia leaves, but nothing I could find online under magnolia plants and trees looked like this.
So number one is Buttonbush, while number two is a mystery.
