Today a section of the bed of Costons brook (near the bridge in Perivale Park) was planted by five volunteers with Flag Iris, which should flower yellow in the spring. Earlier this month, the Greenwayers had removed vast amounts of Himalayan Balsam from the banks and overhanging branches have been trimmed to improve the light reaching the brook.
Regular sessions are planned over the coming months. Hopefully this little known part of Perivale Park will become its pride and joy!
