This <a href="//commons.wikimedia.org/wiki/Ipomoea_alba" title="Ipomoea alba">Ipomoea alba</a> was growing at my friend Zeb's house.  He called it a moon flower, and said that it just bloomed as we arrived and would probably die before the next morning.  I took a shot of it because it was very neat!  The next morning however, there was another moon flower that bloomed on the other side of the same tree, which was very very cool!
