Communal Herbal Knowledge was a year long project in the Central London neighbourhood Church Street Ward.

Following workshops and meetings with various community groups around the use of plant-based home remedies and the passing on of traditional medicinal knowledge reflecting the ethnic diversity of the area, Uriel Orlow and the Showroom London collaborated with gardener Carole Wright to create a local medicinal plant garden at Penfold Community Hub, London together with Penfold Community Hub Gardening Group residents and centre users, Mosaic Community Trust and Church Street Library English Conversation Group and other local residents.

Accompanying workshops put the garden to use and a set of four manuals document the communal plant knowledge that was produced through this process and can be used as a shared tool by everyone. After the official end of the artistic project, the garden project was taken over by the community groups and further developed.
