Morse appears to have been the introducer of Kordes ‘Orange Korona’ and I feel these two files should be merged. Orange Korona (floribunda, Morse, 1959) Orange Korona (floribunda, Kordes, 1955) [KORnita] But which was the seed parent- Bergfeuer or ‘Obergartner Wiebicke’ 1950? I presume that was Horstmann’s Bergfeuer’ 1954.
Latet edit. The 1954 reference on the three year UK trials puts the bred date of the rose back to 1950, so Obergartner Wiebicke is more likely to be the seed parent.
These might have been two distinct roses. 'Orange Korona' by Morse was actually bred by Kordes and introduced by Morse, as documented by the Rose Annual 1960. But why would a rose which already receive a RNRS Trial ground Award in 1953, again be accepted for trials and awarded in 1959 as 'Orange Korona'? The synonym Korona = Orange Korona might be wrong.
Addition: Definitely 'Korona' and 'Orange Korona' are distinct, both from Kordes. The synonym 'Orange Korona' for the 1953 rose as referenced in Botanica's Roses is incorrect. The Dutch Naamlijst of 1986 lists noth roses separately.
'Horstmann's Bergfeuer' was also called 'Bergfeuer' and as the earlier rose, the correct seed parent for 'Orange Korona'
turning point for Floribundas, Korona not only provided a rivetingly intense coloring, but the vigorous, healthy shrub type that makes Floribundas just another branch of the modern family of shrub roses. Semi-double flowers of pure scarlet, paler at the eye with cream stamens and pink anthers!
