Your fairy is called Columbine Elffilter
She is a cheerful sprite. She lives in mushroom fields and quiet meadows. She is only seen on midsummer's eve. She wears lilac and purple like columbine flowers. She has delicate green wings like a cicada.

Those that know me know that I LOVE columbine. It is right up there with violets, and lilacs as my favorite flower.
