The parent species are also included, but the focus is on the amazing developments that have been achieved through hybridization. Close-up photographs show the detailed characteristics that hybridizers look for and work for. Each photo is accompanied by a thorough description of the daylily's colour, size, bloom season, and parentage. In addition to the pictorial encyclopedia, the book offers extensive information on cultivation and hybridization.
