Volunteers Cultivate Rare Tower Mustard in London Conservation Effort
A community-led initiative has successfully grown and replanted over 1,000 tower mustard plants, a wildflower vital for local biodiversity.
More than 1,000 tower mustard plants have been successfully cultivated and reintroduced across London as part of a community-driven initiative to restore one of the capital's most scarce native wildflowers. The project, a collaboration between Citizen Zoo and Habitats & Heritage, aims to revitalize populations of the plant, which is crucial for bees, butterflies, and certain moth species.
Mighty Mustard volunteers formed the core of the effort, attending workshops in March to learn seed-sowing techniques and receiving kits to grow the plants at home. The seeds used were sourced from the species' last remaining populations in London, located at Lesnes Abbey Woods in Bexley and Stain Hill Reservoir in Richmond-upon-Thames.
"We've found the volunteers have become really attached to [them]," said Charlotte Harris, nature conservation manager at Habitats & Heritage, highlighting the project's success in engaging the public. She expressed hope that this volunteer-driven model could serve as a blueprint for conserving other rare plant species.
New plantings have been established at sites including Wimbledon Common, Hounslow Heath, Lesnes Abbey Woods, and Barnes Common. A final planting event is scheduled for Hampton Court Palace's Home Park, utilizing plants grown by both volunteers and the Historic Royal Palaces Gardens Team. Botanist Dr. Mark Spencer has provided expert guidance throughout the initiative.
Elliot Newton, director of rewilding at Citizen Zoo, noted that the organization is exploring future projects to protect plant species threatened by climate change, pointing out that London has lost 185 plant species in recent history. Tower mustard is Citizen Zoo's first plant conservation project in the city, adding to its portfolio of rewilding efforts that include beavers and white storks.
The tower mustard project is supported by funding from the Greater London Authority's Green Roots Fund and Thames Water. Key partners include Barnes Common, Lesnes Abbey Woods, Wimbledon Common, the London Borough of Hounslow, the London Borough of Richmond upon Thames, and Historic Royal Palaces. Newton emphasized the importance of these initiatives, stating, "These projects may sound small, but they're helping safeguard the future of the city."
