Dandelion fairy (Angelicae taraxacae). The dandelion fairy’s hair, identical to the wispy white feathers of the flower’s seeds, disguises her while she lives in the dandelion’s center. When a person makes a wish and blows on the flower, she discreetly floats out with the dispersing seeds, and carries the wish to heaven. Sometimes, a particular wish will move a dandelion fairy so much, she decides to grant the wish herself rather than deliver it to the haphazard whims of the heavens.
Note: I used to have an obsession with fairies and painted them (with questionable skill) and wrote up little taxonomies and scientific descriptions for each fairy species. I recently found some of these old files, so I'm going to re-post them as the season becomes appropriate. Unfortunately, the high-res original images are long gone, but I think the stories are cute.
