Book excerpt: Lots of people want gardens but find the prospect of getting started a bit daunting. P. Allen Smith's Garden Home is P. Allen Smith's inviting solution. Smith begins with his own story: his family's love of gardens and experience in the nursery business, his own education at the great gardens of England, and his discovery that we all have, as he says, "a longing for our agrarian past." After walking us through his own "garden home" and explaining why he made the choices he did, Allen introduces his 12 principles of garden design, discussing such topics as a sense of enclosure, framing the view, texture, pattern, rhythm, and, of course, color. Then, with step-by-step projects, he shows readers how to apply the principles in their own garden homes. For the millions of people who know Smith through his syndicated television show, Weather Channel segments, and appearances on The Early Show, this book is the irresistible invitation to follow him into the garden.
