I agree, C. elegans. Your "bumpy trunk one" is even more bumpy than mine. Aside from that, your pics could be of my plants. In October, I separated that really tall bumpy one and the smallest one from the clump and gave those 2 a separate pot to share. I wanted to be able to see that trunk more clearly. For years, it's looked like the bumps would "do" something but they never have. The clump makes lots of those ball flower things each spring and once a seedling showed up in a nearby pot.
Janet, one of the links you posted had a pic of a "real tree" in the ground somewhere. Since I've had this now about 4-ft. tall clump of trees for about 20 years, that blew me away. Obviously it's had better conditions compared to a potted one, but still WOW! Really enjoyed looking at that.
