Donald,
Hmm, you have a point about the blooms on T. pallida. Granted, I don't think T. pallida has flowers exactly like that of Rhoeo (Rhoeo seems to "carry" them closer to the plant), but they are indeed cupped.
I didn't think about common names being a regional thing, but that is probably the case (which adds to the confusion). I don't know lf anyone else here that has grown Rhoeo, but my Mother knows them as 'Moses in the Cradle' too. But, I don't know where she picked up on the name. She is originally from Kansas, but I can't say if that was something she picked up in Kansas or something she heard here.
Oh yeah, I've also heard of Rhoeo being called 'Oyster Plant' too. Boy.
Transcendentia IS a mouthful.
