The winter gardenAdrian Bloom's Year Round Garden: Color in Your Garden from January to December (Timber Press, $39.95, 0881924571) is gorgeous and absolutely packed with information. This could either be inspiring or daunting, depending on one's level of gardening confidence and ambition. Reader be warned: Bloom's garden is in England the magical gardening isle where everything that gets poked into the dirt blooms to Edenic excess. But, since climate varies wildly even in that tiny country, the plant directories provide a huge range of material, and we Yanks will find more than enough choices to satisfy our local requirements. If your goal is to have something pleasant in the garden every month of the year, pick Bloom.
