Here's what mine looks like now. It seems quite consistent with SS's website picture, which BTW seems like a quite attractive cultivar. If mine colors up like that in the spring or summer I think I'll keep it. Although I quite doubt that it is in fact 'Pacific Knight'. It seems to me that SS puts their most colorful pictures on their website, and they would have used a solid red coloration if it ever happened. If it turns solid red in the Pacific Northwest sunshine, then I would think it would also in Wisconsin. But then again there are those regional differences and I am not exactly an expert at this.
Comparing this picture to the one at the top of this thread, it does seem to have reddened up noticeably on the tips, the back sides and along the edges down to the leaf shoulders. I am left to wonder if this plant is more red in the winter or in the spring or summer.
