Beautiful! Love these leaves. Is this a cool grower? A friend just gave me a small plant, simply saying it’s a common plant, not fussy. Keep it in the house, even less light than a phal. Pretty plant, but not the very striking colors of your plant.
No, the leaf markings of each different variants of discolor are very distinctive. It only varies if too much light is given by becoming more yellow to burnt, or slows growth and may get smaller, or die.
