I could smell these datura blossom's lovely fragrance from about five feet away. They emit their fragrance at night to attract moths, I guess, for pollination. Tomorrow they will shrivel and hang down while other buds begin to open. This was the first time I ever checked them at night and got a chance to see how beautiful their scent was. I know their seeds are poisonous so I've been cutting off the flower stalks as soon as the blossoms fade.
