Any of several flowering plants belonging to the family Asphodelaceae. This common name is variously applied and thus much misunderstood. The asphodel of the poets is often a narcissus; that of the ancients is either of two genera, Asphodeline or Asphodelus. Asphodels are hardy herbaceous perennials with narrow leaves and an elongated stem bearing a handsome spike of white, pink, or yellow flowers. Bog asphodel (Narthecium ossifragum) is a small herbaceous plant that grows in boggy places in Britain.
