Yes, I long for a follow-up also. Continuing to babble may help. People get busy, distracted.
Your pic is more than a lovely consolation prize! I've also noticed the Yuccas blooming around here lately. I don't want these plants in my yard, but admire them as drive-by sights, big, striking white spikes.
Saw something yesterday that's similar but HUGE, had a bloom stalk that was around 15 feet. I was going 55... If it hadn't been raining, I would have stopped for a pic of what I'm almost certain was Agave americana (century plant) about to put on a rather large, showy show. Hopefully I will have occasion to drive by it again while the show is going on, for a pic.
A few years ago there was an article in the local paper about a lady who had caught the city maintenance crew about to cut the flower stalk of her century plant because it was a few feet under power lines. Once she explained what it was, they agreed it should be left alone until finished blooming, had a pic of it with the article, the lady and the maintenance guys standing by it. I went by there the next day doing errands and wasn't alone when I stopped to take a look at it. As you can imagine in a really small town, such an interesting story and plant caught a lot of people's attention.
