They are such a wonderful flower.
T. sessilifoloium grew for me much the same as with you. Nothing like the pictures in the wild habit wise. By this I mean a dwarf, compact plant.
My first reaction to the T. moritzianum was "that's not what I have it as" but having looked out this picture it is possible that this is different though obviously closely related or simply a different form of the same species and therefor a synonym? Taken at Harry Hay's as T. smithii.
