The Nairobi suburb that stands on the land where Blixen farmed coffee is now named Karen. Blixen herself declared in her later writings that "the residential district of Karen" was "named after me". And Blixen's biographer, Judith Thurman, was told by the developer who bought the farm from the family corporation that he planned to name the district after Blixen.
Blixen was known to her friends not as "Karen" but as "Tania." The family corporation that owned her farm was incorporated as the "Karen Coffee Company". The chairman of the board was her uncle, Aage Westenholz, who may have named the company after his own daughter Karen. However, the developer seems to have named the district after its famous author/farmer rather than the name of her company.
There is a Karen Blixen Coffee House and Museum in the district of Karen, located near Blixen's former home.
Karen Blixen's portrait was featured on the front of the Danish 50-krone banknote, 1997 series, from 7 May 1999 to 25 August 2005. She also featured on Danish postage stamps that were issued in 1980 and 1996.
