The parentage of 'Happy Anniversary' (HT, G. Catt, 1997) is being shown as
Kardinal (hybrid tea, Kordes 1967). This is incorrect as it was a sport of a 'Kardinal'.
I am guessing that it was more likely to be a sport of 'Kardinal 85' than 'Kardinal' 1967,
but there is nothing in the references to indicate which one.
