Book excerpt: A delightful compendium of writing on plants. The passion for gardening and the passion for words come together in this inspired anthology, a collection of essays on topics as diverse as beans and roses, by writers who garden and by gardeners who write. Among the contributors are Christopher Lloyd, on poppies; Marina Warner, who remembers the Guinée rose; and Henri Cole, who offers poems on the bearded iris and on peonies. There is also an explanation of the sexiness of castor beans from Michael Pollan and an essay from Maxine Kumin on how, as Henry David Thoreau put it, one "[makes] the earth say beans instead of grass." Most of the essays are new in print, but Colette, Katharine S. White, D. H. Lawrence, and several other old favorites make appearances. Jamaica Kincaid, the much-admired writer and a passionate gardener herself, rounds up this diverse crew. A wonderful gift for green thumbs, My Favorite Plant is a happy collection of fresh takes on old friends.
