The Flower Fairy books are on the shelf a few feet behind me right now. I bought them, along with Beatrix Potter and Winnie the Pooh, for when my grandchildren visited. They are a bit old for them now I'm afraid.
The Flower Fairies, when I was young, were the beginning of my learning about plants. By the time I was about 8 I knew what most wildflowers, trees and weeds were called and where they grew.
