Rosa 'KORaruli' (Sunny Sky Eleganza®)

Rosa 'KORaruli' (Sunny Sky Eleganza®) was bred by Tim Hermann Kordes in Germany and is a cross between two unnamed Rosa seedlings. It was patented on December 20, 2011 and has patent number PP22,352. It is a hybrid tea rose.

At Brookgreen Gardens, we have been continually impressed by how Rosa 'KORaruli' (Sunny Sky Eleganza®) has performed. Hybrid tea roses have a reputation for being difficult to grow due to disease pressures, especially from black spot (Diplocarpon rosae), but we have found this rose to show very little signs or problems with black spot or other fungal problems. The flowering is consistent and highly attractive, the shrub is generally full with leaves, and is overall a strong performer and great addition to the landscape.

Black spot can cause leaves to develop black spots with blurred edges, yellowing leaves, and eventually partial or entire defoliation. While black spot is rarely fatal, it can weaken the rose by reducing its leaves and therefore its ability to photosynthesize. Although similar in appearance to cercospora leaf spot, black spot can be distinguished by the less defined and more feathered edges of the spots. As with many fungal problems, issues are generally worse in areas with high humidity. Black spot can be treated chemically.
