So often a garden book that proves ideal in one locality is utterly useless a few hundred miles East or West. Shops everywhere will rejoice to know that the author of this book has lived and gardened across the continent from Washington (state) via the Canadian shore of Lake Erie through Connecticut to a New York backyard which she makes yield house flowers over a long season. There are chapters on the flowers she has found most satisfactory giving their behaviors under various climatic conditions, different sections of the country, etc.--and one chapter that will amaze you--entitled ""Flowers I Have Never Grown."" Such honesty is heartening. The style is informal, chatty and for all its practical side it is really Miss Ellis' Garden Memoirs.
