Classic Garden Design by Rosemary Verey (Congdon & Weed: $24.95) gives us the author of "The Englishman's . . . " and "Englishwoman's Garden" doing what she does best: bringing together the varied elements of gardens past with the realities of gardens present in readable, authoritative style. Unlike the two previous works, "Design" offers more practical guidelines, but its true delight lies in Verey's fond appreciation for what has gone before and how it has planted the seeds of what can still be. You needn't own an English estate, or even a large yard, to enjoy and make use of the ideas placed within reach here.
