When the wild thistles—which I cultivate and move into my flower beds—are done with their lovely purple flowers, the resultant seed pods break down into these crazy looking clusters of fluff. Each seed is attached to those very light, feathery appendages, which catch the wind and blow all over the yard, ensuring the thistle's continued existence the next year. In the spring, I spend a few months faithfully digging up the tiny plants as they start to grow in the lawn and driveways. Goldfinches and other birds LOVE to nosh on these when they get to this point, which is the real reason I continue to do the work to keep them in the beds and not in the lawn where they'll be mowed and never mature.
