Brugmansis were initially known as Daturas. However, because Daturas were associated with being poisonous they did not sell very well. Thuspart of the family was renamed Brugmansias. They are still poisonous but as has been said earlier the flowers are pendulous whereas the Datura flowers point upwards. Daturas (Thorn apples) are normally annuals whereas Brugmansias (Angels trumpets) are perennials but not winter hardy.
