I was out walking the dogs when I spotted this little branch that had fallen from our old oak tree:
The grey-green hairy-looking thing is a tillandsia, a type of bromeliad also known as an air plant. Air plants attach themselves to trees and other surfaces and grow without the benefit of soil. They generally don't harm the trees they inhabit, either, but evidently this one had grown too large and heavy for the spindly twig to support it.
I grew up around air plants and I've seen this happen lots of times, but on closer examination I spotted something I'd never noticed before -- a fluffy sprout that looks like seed pod:
Now I wonder, did the plant know it was doomed?
