We've all picked a dandelion, blown its seeds into the wind, and made a wish. The dandelion has three phases: the yellow flower, the puff-ball, and the dissemination of the seeds. Some say this is akin to the sun, the moon, and the stars. I think that's pretty romantic. (But I wouldn't want a bouquet of dandelions!)
