In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also ...

Distribution and habitat
Lilieae ''s.s.'' are distributed in temperate Northern Hemisphere areas, with the main
centre of diversity in the
Qinghai–Tibet Plateau, where about 100 species may be found. Other areas include East Asia, Central and West Asia, the Mediterranean Basin and North America.
