My best attempt is a big hanging basket with a fragrant begonia in it. Right at nose level! It's hanging from a huge oak branch that also has orchids growing on it.
I did see a magnificent "living wall" at Epcot last spring. Truly a plant tapestry! Wish I could find one of the pictures I took of it.
Here's a shot of an oak tree at Selby Gardens that is festooned with bromeliads and orchids!
