A rowan tree has been planted in Archbishop's Park as part of a programme teaching children about the importance of trees.
The mountain ash variety has been donated by nearby residents Mark Thistlethwaite and Deborah Ramsay.
The site of the new tree is in the educational garden near the Lambeth Road entrance and was planted with the help of young people who also live nearby with a daily view of the park.
The tree will shed its leaves in winter and new dark green leaves should appear every April. Small white flowers come in mid to late May and turn into berries enjoyed by birds. If looked after the tree should last until the end of the century.
A plaque recording the event will be added at the base later this year.
