Congrats on flowering this species. My rothschildianum is in flower at this time and the flowers last over a month and a half. It is my second flowering and the flowers last alot longer and the plant has a total of 6 growths measuring about 35 inches in leafspan. The first time it bloomed in 2004 the flowers lasted only three weeks. Both time the plant flowered with 4 flowers and they measure at 11 inches from petal to petal tip.
