Ian Foster is a local who has spent a long time researching and exhibiting historical facts about Chelsea. He has recently identified a tree, Morus Nigra, which likely dates back to the late 1800s. The mulberry tree, as it is better known, has long featured in the history of the area. They thrived in the local conditions of Chelsea and a nursery was planted in Chelsea Park in 1719. This was used for the production of silk fabrics by John Appletree. 2000 trees were planted in Chelsea Park for this purpose. Although the endeavour ultimately failed the trees remained.
