This was not my intended target. My plan was to get another (better) shot of the pink flowering tree from Oct 14.
No parking was to be had nearby, so I had to park 2 blocks away. When I got out of my car, I saw the landscape plantings and my plan immediately changed. I took at least 30 photos of two of the large plants. One was a yucca, of the same variety posted by @webfoot on Oct 9, 2012. The other was this, which I also suspect is a yucca, considering the similar imprint on the leaves. I was attracted by the way the long blades bent and swirled, resembling striped snakes. This plant is over 4 feet tall and maybe 8 to 10 feet wide.
This is a yucca, yes?
