Seedfork said:I think that the cultivar 'Baroni' is described as having pink at the base of the leaves would be a could tip off as to which plant is which. I have seen it referred to as "Pink Socks" or "Purple Socks" if is more purple tinted.
Hemerocallis citrina also has the pink socks, so I think the biggest difference between the two may be height. I looked into this years ago when it came up somewhere else and just managed to unearth a couple of articles I'd kept in my files about the early hybridizing in Europe and
H. citrina. It looks to me as though 'Baroni' may have been misinterpreted by some to be an "improved"
Hemerocallis citrina even though it is a hybrid with
H. thunbergii. I did notice an apparent misinterpretation also of
Hemerocallis citrina Baroni as Baroni being a cultivar name whereas in the original context Baroni was intended to indicate the author of the name.
