Duck behind a hedge, lift the latch of an overgrown gate, follow the meandering path to wherever it leads. You just may encounter a delightful surprise: a lively jumble of greenery and bright blossoms, a trickling fountain, the chirps, warbles, and songs of birds, perhaps a bench placed in the shade of an old tree. Now in its 15th successful year, "The Secret Garden Calendar" opens up to a dozen lush sanctuaries that will soothe the spirit and recharge the mind. A verdant French garden surrounded by weathered stone walls. An intimate breakfast nook overlooking a pretty array of tulips. Every one is an escape from the outside world, its own little paradise. Photographs are enhanced by gardening quotations, tips, and appreciations.
