There are two different red hybrid tea roses with this name, both bred by Kordes in Germany.
One was released in 1968 (br...Read Moreed by Reimer Kordes), cultivar name 'KORliegra'.
The other, 'KORcolumna', was released in 2004 (bred by Tim Hermann Kordes). It has two other trade names: "Walter Sisulu" and "My Valentine". USPP # 17047.
'KORcolumna' is exceptionally healthy. It is highly resistant to black spot and powdery mildew, and is one of the few hybrid tea roses that have won an ADR (Germany's trial for health and performance without the use of chemicals, and the inspiration for the Earthkind trials in the US). I've seen it grown here on the east coast with healthy foliage all season without the use of fungicide.
