Cicely Mary Barker (1895- 1973) is the creator of the famous flower fairies. Her work is almost like a fantastical flower taxonomy, as she draws a flower or plant of some sort and then creates a corresponding fairy to be a spiritual representative of sorts. I love flower fairies because of the art style, I don’t know if it’s Victorian or what, but it’s old school and I like it. I also like the joy and motion the fairies display as they frolic among the flowers or the pensive serenity of those who are just sitting or standing.

there are also several books out as well, a good one to look for would be The Complete Book of Flower Fairies, but not all of the fairies are in this book and the newer edition cropped some of the pictures. There is also the option of looking for the books that are just one category of flower fairy, like flower fairies of the spring or flower fairies of the summer, if you get all of those you’ll have all the pictures, but if you want an overview the new edition isn’t bad.
