Ahead of Valentine's Day, the Nelson Mandela Foundation has unveiled an orange and vermilion rose named after the anti-apartheid leader who became South Africa's first black president.

The foundation, which promotes Mandela's legacy, showed off the rose at its headquarters on Thursday.

The Mandela rose is expected to be sold locally and internationally and proceeds will go to the foundation. CEO Sello Hatang says Mandela appreciated gardening and cared for the environment.

The foundation is marking the centenary of the birth of Mandela, who died in 2013 at the age of 95.
