I really was disappointed that the blooms didn't open while you were here. They're pretty enough in pictures but to see them first hand makes a big difference.
Here's a shot taken from the front side of a bloom. (Lit by a flashlight)
And from the backside.
And here's a shot of the plant with three blooms open at once.
It's a shame the blooms only last one night. They're sooooo gorgeous.
