Update:5/8/08 - this plant grew wonderfully for me and produced many blooms. It became very large. I did not water it very much. Then, I went on two long trips in October and November of 2007. The temperatures were unusually hot during these months. A friend of mine graciously offered to take care of my plants while I was gone. I forgot to tell her not to water this plant unless it appeared to reallly need itr. She watered it often along with my other plants apparently over-watering it. Sadly, it died.
