The Beauty of Weeds

I found those beautiful flowers by the side of our house. They are tough in many ways: tough to pull out, tough to give up during a drought, tough to give up in a dry location, tough to walk on, tough to mow over with the lawnmower. Yesterday, I walked around the house to find some of them in full bloom. That made me think of the (often) hidden beauty of things we label as undesirable.

What was the last thing, plant or animal in nature that astonished YOU?
