That is one stunning paph, Cheryl. Love the shinny surface and the colours. What does the foilage look like? I guess that always inportant to me since that is what your stuck with most of the time.
Paph's should stay in bloom for around 6 to 8 weeks, especially if kept watered and the humidity up. Don't water paphs at night or if you do make sure it's warm and bright, so it can dry off before it goes to bed.
They like to be repoted after they flower too, although I have let mine go almost 2 years if in medium bark mix. They should flower twice in a year or a little better, depending. OK, stepping off the soap box now.
