Healthy looking plant- congrats!
However, pinkoyd might be on to something there about that being an alba. One of the differences you can see between viridis and alba is where the leaves attach to the stem. In viridis, the leaves remain wide all the way down to the point of attachment, where in alba they narrow down to center margin of the leaf before the point of attachment. It looks in your three most recent pics like the leaves narrow down. A pic of the attachment for a viridis is attached, so maybe you can do a little compare and contrast since your view of the plant is better than the pics can represent.
Either way, it's awesome to see success from seeds, especially out in the elements. Good luck with it!
