My Senecio articulatus looks elongated. During the day it sits on a window ledge. Why elongated? Could this be normal growth?

This morning I googled Senecio articulatus. Most of the images did not look like my plant, but an interesting and very cool thing happened. I found a link to a botanical illustration site. One Senecio articulatus illustration was dated 1781. Gives me pause to think my plant could be connected to the plant in the illustration.
I spent some time looking at several illustrations. The images are so beautiful.
