No, Rosy Dock is not someone you should know; apparently it's a pest, a non-native species of flower introduced more than a hundred years ago into Australia, where it's exuberance is threatening native species. (Can you say "scotsbroom" and "evergreen blackberries"?)
As an environmental message book, Jeannie Baker's prose is awkward at best; but the book is worth reading for the illustrations-amazing collage that draws you in to take a closer look at a beautiful, but troubled land.
