Mine is an EA plant and it looks more like your second photo. I have a feeling that Chelsea is not a stable cultivar. That's just my best guess... But I might also wonder if it's a matter of how much light it's getting. Maybe it keeps the concave leaves in higher light? In the first photo, the leaves are a light green like they've been growing in strong light, whereas the second one shows deep green leaves which is an indicator of a shady position or bright indirect light.

Yeah, EA has shipped out a lot of the "chelsea's" recently and they look like your second pic.

Little disappointing as the dimples are practically gone and the color is way off.

Its hard to find the nice light green ones. Maybe I should try to find a Krinkle.

Maybe light? But I have mine in a very sheltered East window and mine is about mid range of both these photos, in color and shape. Either that or just differences in clones.

I'm starting to think it's a different clone. The leaves are so dark and don't look that green to me. They are almost more purple/brown, kinda round in shape and most leaves have no dimples. Almost like a very dark Motoskei.

I tend to think these are different clones, too. Mine is a dimpled one, from Joni. But I've seen the flat leaved / dull green / more boring ones (sorry, Denise :-( ) at big box stores before, from Exotic Angel.
