On Thursday, Sept. 20, Jean Gaddy Wilson hosted a party to bid farewell to Audrey, her 65-year-old, 40-foot-tall, half-ton blue cactus friend. Also known as "Century Plants," blue cactuses bloom only once in their lives, then die. Audrey sent a flower stalk soaring into the sky this spring, bloomed and then expired. But she was sent off in a style befitting her life.
