The focus of this book is the flowers found growing in the woods, fields, roadsides, and beaches of the islands of Casco Bay, Maine. Because my summer home is on Chebeague Island, most of the species recorded here were observed on Chebeague, and most specific place names refer to Chebeague. However, the flora of the islands of Casco Bay (and surrounding mainland) is all very similar; so, this book can be a guide to the wildflowers of the region. I wrote these pages primarily for myself, because I wanted to learn the wildflowers on Chebeague, but I also want to share them with anyone who may enjoy these plants. The species included here are mostly wildflowers although there are some quirky ones, like sheep sorrel (a horrible garden weed) and bittersweet (our worst invasive). Some may not consider these flowers; but of course they are, they're flowering plants. There are also some species here that are probably escaped ornamentals (e.g. foxglove and meadow pink), and so are not strictly "wild" flowers, but they are certainly pretty and worth including.
