Yes, no two flowers on Tolumnia's will be the same. They consistently change. Great growing BTW!!! I just noticed today that one of my two has about a 2 inch spike on it- I can't wait!!!! LOL....
Very nice! I have one and hope it blooms one of these days! Does it get quite high light? Mine does have the purple colouring on the edges of the leaves so it should be getting enough light I would think.
