Lilium is a genus of bulbous perennials grown for their very showy, often fragrant flowers. Among the 100 species, there are four main flower shapes: trumpet, bowl, recurved, and funnel. Various lilies bloom from spring to fall, giving rise to early season, midseason, and late season designations. There are 8 divisions of hybrids: Asiatic, Martagon, Candidum, American, Longiflorum, Trumpet and Aurelian, Oriental, and Other, plus one division of all true species. Lilies are useful in woodland gardens and wild areas, as cut flowers, and even in containers or rock gardens, depending on the species.
