A tree was planted to celebrate the Diamond Jubilee year, which was donated to the Ahmadiyya Muslim Community.
Women and girls from the group gathered on Tooting Bec Common to plant the commemorative tree last week.
The tree was awarded to the Ahmadiyya Muslim Community charity by the National Tree Council, and is one of 60 donated to mark the occasion.
Councillor Nicola Nardelli, deputy mayor of Wandsworth and Pauline Buchanan, director general of the tree council took part in the event.
Nasira Rehman, president of the Ahmadiyya Muslim Women's Association UK and missionary Inam Naseem Bajway also attended the ceremony.
About 150 girls sang a jubilee song, while some read out letters they had written to the Queen.
The young women of the community planted a further three wild cherry trees along with the diamond oak, which they raised funds for.
