After pollination and flowering is finished, the dandelion flower dries out for a day or two and then the seed-bearing parachutes expand and lift out of the dried flower head. The dried part of the flower drops off and the parachute ball opens into a full sphere. After the seed is released, the parachutes lose their feathered structure and take on a fuzzy, cotton-like appearance, often called “dandelion snow”.
Close your eyes, make a wish, and blow gently until the “snow” (your wish) take flight.
Just don’t do it over my lawn.
those would be full wishes ;-)
