I am not in a position to wander outside and check on the agave but I have family, in this case my brother, who are willing to do just that. He took some great pictures of my flowering agave.
The upper branches have opened up and the flowers are working towards blooming, particularly those at the lowest levels.
You can't see any bold color so they aren't there yet but there is progress. I'll let you know as the blooms progress.
