That looks very much like it. I think it must be the moist environment that gives them a more robust growth. Here it's a hardscrabble life for anything that likes water or humidity. Ours is three and I forget about it completely until it blooms at what seems to me to be an odd time. But very welcomed. I haven't tried rain lilies but after reading the article, good one by the way Janet, I will keep an eye out.
edit I thought the stamens look right but a better photo would have helped.
