I'm sorry you missed the show. You've only got one night to catch it, and it's usually late at night. If you don't know it's happening, it's very easy to miss. I've missed several blooms in the past. I can't tell you the number of times I didn't even know there was a bud let alone that it was blooming until I could smell the perfume from the flower
. It's very strong and intoxicating. Mine was kept indoors so the aroma was a dead give away.
I can't recreate the smell for you, but here are a few pictures of what it looks like in bloom.
