‘KORtragoso’ is a new and distinct variety of Rosa hybrida which is characterized by the combination of a compact and bushy growth habit, dark green and semi-glossy foliage, excellent resistance to common rose diseases, and double-type flowers borne in panicles of up to 8 blooms. The small flowers are held upright and exhibit yellow petals with a red petal edge and a light fruity fragrance. The new variety propagates successfully by stem cuttings and grafting and has shown to be uniform and stable in the resulting generations from asexual propagation.
