@Cinta I went back and read the thread you referenced. I find T. pallida variable in appearance depending on the growing conditions. The same plant can look really different. It needs some room to spread out to look its best so I have it in a broad, relatively shallow container. I'd probably prefer it in the ground, but it has simply looked yucky where I've tried and then it's not reliably hardy through winters here. We have the occasional winter that just is too cold. I think T. spathacea may be variable in the same way. The plants remind me of each other in the general shape and both have brittle leaves that break easily. I guess if it lives long enough for me, I'll find out if spathacea is variable in appearance depending on growing conditions.
