Soft-lit flowers of a rhododendron on the campus of Reed College here in Portland. Until we moved to Oregon, I had no idea there were so many varieties of rhodos. In fact, I don't think I had ever seen one in bloom.
If you really want to impress your friends, you can casually mention that "rhododendron" comes from the Greek for "rose tree". (I learned it on dictionary.com while figuring out how to spell "row-doh-den-druhn".)
