Joanna Rajkowska (born 1968) is a Polish contemporary artist who came onto the Polish art scene in the 1990s. Her most famous work is called "Greetings from Jerusalem Avenue", a 15-meter-tall (50-foot) artificial palm tree installed on Warsaw's Jerusalem Avenue. The installation was organized by the Warsaw Centre for Contemporary Art (13 December 2002 – 13 December 2003). Since then, the palm tree has become a permanent fixture of Warsaw, as it was not removed at the end of the official exhibition but instead came under the protection of the President of Warsaw.
