People across Hounslow are being urged to work together to help protect and restore one of the capital’s rarest plant species.

It’s thought the Turritis Glabra, known as Tower Mustard, is currently only found at two sites in London.

A conservation programme has launched to reintroduce the rare herb to more areas starting with Hounslow Heath.

Citizen Zoo has launched a collaborative conservation programme to reintroduce the rare herb.

The project is funded by the Mayor of London’s Green Roots Fund and Thames Water and brings together Hounslow Council and Lampton Countryside Rangers, alongside a network of other land managers and community partners.

Volunteer citizen scientists in Hounslow will learn how to grow and care for tower mustard from seed, at home, beginning in March.

In the autumn, they will join coordinated planting days at carefully selected sites on Hounslow Heath.

This is one of just five suitable sites across the species’ historic London range.

Tower mustard is currently thought to survive at just 30 sites across England and currently at only two sites in London, where seeds have been sourced for the project.

Plants grow to around one metre tall and produce delicate white flowers.

Tower mustard supports vital pollinators including native bees, butterflies and rare moths.
