Whoops, the bloom lasts for 5-6 months.
Sherry, you have a Chinese yellow banana, Musella lasiocarpa, sometimes also known as a golden lotus. At maturity, the flower stalk may reach 6 feet in height. For its tropical look it is surprisingly hardy, supposedly to Zone 7.
Well, be darned! That's a new one to me. What an interesting plant!!
Douglas, the store called it a Golden Lotus Banana Plant - Guess that is their marketing name. The bloom is much larger when it is completely open.
