Durston Garden Products has teamed up with Norwich City Council and City College Norwich for a two year sustainable media perennial planting project in the city.
The aim of the project is to grow and use perennial plants where possible alongside bedding plants, and to use peat-free compost instead of traditional peat-based products to provide displays in Norwich.
The project has come about as a result of a £6,000 grant from Defra and RHS Britain in Bloom.
The project is to act as a trial using a variety of composts supplied by Somerset-based Durstons including peat-free, as well as the standard peat-based products and John Innes varieties.
The composts will be used to create displays of plants in areas such as civic and community locations in and around the city and will be monitored to establish performance over the next two years.
National sales manager Ruth Green said college students working with the council's parks and gardens team were creating the displays.
She added that the project showed a cost-saving way forward for councils.
