Care. Full sun or light shade; a sturdy support is essential; feed 2–3× per season; prune ⅓ in spring; high disease resistance — minimal preventive care thanks to its Kordesii-genetics.

About the name

Name. 'Rosarium Uetersen' — after the Rosarium Uetersen, the famous rose garden in the town of Uetersen (Schleswig-Holstein, Germany). It is the historic 'home' of the rose trade in northern Germany, next to which the Kordes breeding station is located at Sparrieshoop. The Uetersen rose garden was founded in 1929; it is one of Germany's leading public rose gardens. The name is a tribute to the place of origin of Kordes-breeding.

Breeding. Bred by Reimer Kordes (1922–1997, son of Wilhelm Kordes II) at the house of W. Kordes' Söhne (Sparrieshoop, Germany). Code KORtersen. Introduced 1977. Parentage: 'Karlsruhe' (Hybrid Kordesii, Kordes 1957) × an unnamed seedling. Karlsruhe, of the Kordesii class, passed on its high disease resistance and apple scent.

Significance. A classic German climber of the 1970s. 100–142 petals — one of the records among climbers. The apple scent is unusual and recognisable; a rarity among climbers. New Zealand Gold Star of the South Pacific 1980 (NZ Rose Trials). ARS rating 8.5 (very good to excellent). 2 sports (2009): 'Uetersens Rosenkönigin' ('Queen of Uetersen') and 'Uetersens Rosenprinzessin' ('Princess of Uetersen'). ADR not confirmed in open sources (despite its German origin).
