I think this might be 'White Butterfly,' but I'm not sure and would like your input.
It has the faintest dark green edging like 'White Butterfly,' but I don't see any leaves that resemble those of the plant in the database; the leaves on mine are all a light creamish green color with a little bit of darker green edging. I haven't had it very long so I don't think the color is environmental; it looked this way when I purchased it a few weeks ago.
