probably not because of Karl's homosexuality, which he lived openly in his later age, but of his other health problems. Olga's husband became the object of scandal several times for his closeness with various men. The most notorious of these was Charles Woodcock from the United States, a former chamberlain whom Karl elevated to being Freiherr Woodcock-Savage (English: Baron Woodcock-Savage) in 1888. The resulting outcry forced Karl to renounce his favourite. In 1863, Olga and Karl adopted Olga's niece, Grand Duchess Vera of Russia, the daughter of Olga's brother Grand Duke Constantine.

Olga was also very interested in natural science and collected minerals systematically. Her collection was left to the Staatliche Museum für Naturkunde in Stuttgart. As of 2011 part of the collection is still on display. Her name is attached to a geological formation in the Northern Territory, Australia. In 1871, King Karl I elevated the German-born Australian explorer Ferdinand Mueller to being "Freiherr von Mueller". He repaid the compliment as follows. A series of massive rock formations was discovered by the British-born Australian explorer Ernest Giles in central Australia in 1872. Mueller was Giles' benefactor. Giles had wanted to name the tallest peak Mt. Mueller, but Mueller prevailed on Giles to name it Mt. Olga, in honour of the queen. The entire geological formation then became known as "The Olgas", before the
