Busy roundabouts have been chosen by local authorities in Glasgow, Sheffield, Leeds, Birmingham, Swindon, Liverpool and Woking, sponsored by Enterprise and its philanthropic arm Enterprise Holdings Foundation.
Sue France, director of Dunnett's meadow specialist company Pictorial Meadows, explained: "Public sector budgets are very tight. With so many priorities it is very hard for local authorities to allocate funds to new landscape initiatives even if they are sustainable and have local social and environmental impact.
"This project is an example of public, private and third sectors working together to achieve something that will make a long-term difference. We know many local authorities are seeing this as a pathfinder project that will enable other more long-term planting schemes in the future."
