Father John L. Fiala devoted 10 years to this book, a unique treatise that is both a scholarly monograph and a personal tribute to the beauty of lilacs. Since going out of print, it has become almost impossible to obtain at a reasonable price. Sometime in the future a revision and expansion of his work will appear, but in the meantime we have released this facsimile paperback reprint in response to extraordinary demand. It includes the 398 color photographs from the first edition and makes Fr. Fiala's work again accessible.
