Hmmmm. Mine, Patty's and the SS picture could all be the same (possibly incorrect) cultivar. In fact the SS picture and Patty's appear quite similar except that Patty's has reddened up a bit, but the red leaf-tip shape is there and so is some of the olive green. The SS picture looks like it would redden up in Fall/Winter to look alot like Patty's.
Mine, however, seems to be losing the redness while lightening up in the green areas. It's going the wrong way, maybe the shipping and transplanting has it seasonally confused.
I will keep an eye on it.
