I purchased a double fan of Which Way Jim in the spring of 2014. It has multiplied some, but not a great amount, maybe 5-6 fans now.
I noticed that the database pictures vary a lot, and even my own pictures of WWJ vary from very black to light magenta-purple, which tells me that it does fade quite a bit throughout the day. It gets full sun here in southern Indiana.
I haven't seen anything spectacular about this daylily that stands out. 2-way branching and low bud count. I do like the black color at the beginning of the day before it fades, but I think this one will not be in my garden much longer unless I move it to the shade to see if that helps retain its color.
