@spell007 Welcome!
I just ordered this from PW this past summer and it was sent to me in a small pot w most of the tops cut off for shipping. I repotted it and kept it outside for the summer and it grew like crazy. I brought it inside for the winter and it is in my living room where I have a 9ft long window that faces south, it is across the room and gets indirect light. So far it is doing well, but my individual leaves are no where as big as yours. I wonder if thinning out the leaves and only leaving a few will make them get larger? I love the coloring too on the underside of the leaves. I had a few years back that I purchases at Lowes, named "Pegasus" and I understand that they are the same plant.
