A Neo for sure - but impossible to say what the species or hybrid might be - (I'd lean towards a hybrid) there are many hundreds of them.
Slowly move it into stronger light but even most Neos like a little shade especially in the afternoon. In Florida you don't have to worry so much about the air drying out when the temperature gets very high. You have about the best growing conditions possible in the US.
As the plant gets more light the leaves will shorten and broaden, and the reds will become more intense. Those older leaves were probably growing in the Winter with less light and shorter days.
Hey Thank You both.
I've placed it in an old Hickory Log for now, and it's getting dappled sun/shade, I can move the Hickory log to more sun, as the Oaks leaf out. Can't wait to see what it does for color !
