'KORresia', 'Friesia') is a rose variety developed by Reimer Kordes and introduced in 1973.

Its sunny yellow blooms are large and flat with 17 to 25 waved petals, reaching an average diameter of 8 cm (3.2 in) and have a very strong fragrance.

The high-centered flowers appear solitary or in small clusters in a blooming period lasting from June to September.

The plant has light-green, glossy leaves, forms upright, bushy shrubs with about 40 to 75 cm height and up to 60 cm width, is very disease resistant and hardy (USDA zone 6b) and can be grown on the ground or in containers.

It is used as a parent rose, leading to cultivars such as Rosa 'Sun Flare' (Warriner, 1981) and 'Morden Sunrise' (Davidson & Collicutt, 1991).
