Hi, Love your pic. beautiful paph. I am new to growing these and only have two. I don't know if two blooms per stem is common or not but my Lady Luck (Winston Churchill 'Indomitable' FCC x Skip Bartlett 'White Pepper' HCC) did the same thing. It had two stems, one with a single bloom and the other with 2. All blooms opened beautifully. They do take time to open so give urs time. Enjoy! Bill
