My aunt and garden mentor sent me home with some plant starts this summer. Among them was what she called a moon flower. I planted the starts and waited patiently. In September, it happened! A bloom and what a beautiful one!
From my research this seems to be a Datura Wrightii. Some common names include Moon flower, Jimson Weed and Thorn Apple.
It has some hallucinogenic qualities I hear and is considered poisonous. YIKES! I like it enough to keep it around, though.
I don't remember seeing any of these seed pods, but they look pretty neat.
