(Other definitions for asphodel that I've seen before include "Elysian plant", "Lily-like plant, the flower of death to ancient Greeks", "Lad hopes (anag) - flower", "Plant of lily family - lop heads (anag)", "blooms from Elysian fields", "liliaceous plant", "Lily", "Flower of lily family - old heaps (anag)", "Shop deal (anag.)" and "Old shape (anag) - plant".)
