Wow that's beautiful!! I would love to have one, but the size is much more than I can handle!
Mine was given to me by my father and bloomed for me for the first time this year. It is not that big, it is a division of one of his and has six pbulbs, tallest one is about 18 inches, rest about 8 - 12 inches tall, in a 5" pot. Has 7 flowers and is really quite beautiful!
