Don’t miss this wonderful NYT video of how Dandelions propagate using little helicopters, called pappi, to generate lift to launch themselves and become airborne. While we fret over them landing in our yards, you can’t help but marvel at how several species of plants “learned” principles of aerodynamics eons before the Wright Brothers took to the air.
As the video points out, we can learn a great deal from understanding how Dandelions and other members of the Plant Kingdom function.

As marvelous as the pappi are, I am just amazed at how Mother Nature can make things grow so successfully, even in the hardest to reach places like in cracks in rock, your driveway or sidewalk. I know if I tried to grow anything in the rocks below, I would fail miserably, but some how as Jeff Goldblum says in Jurassic Park, “Nature will find a way.”
