Here is the same plant I asked about 1 week ago. I separated it from the mother a year ago back in April. I was remarking about how fast this plant is growing, so here is documentation for you.

Has anyone ever seen growth this fast?
When I say this plant is growing faster than all my other Sans (including its mother and mother's new pups) I'm not kidding. This plant was a single pup in April 2015, and this is its second pup. Clearly I did something right, but haven't done anything to this particular plant differently than any of my others. It is absolutely beautiful though, and is my favorite. :)

If you'd like to follow my Sans you can watch them on Facebook here:
