Pretty flowers!
And since you seem to know what you're doing with them (sorry to hijack the thread)... my friend's AV has also been full of blooms, but when he came back to his office after being away for a bit he found that the bottommost leaves in a circle around the plant had all drooped. The blooms and other leaves are fine.
He thought it was underwatering and he does tend to be a bit of an underwaterer. But those leaves are now just dying instead of perking back up after being watered. I was wondering if you'd ever seen anything like that before or happen to know if that is a normal response to being underwatered for african violets.
