These flower borders are stimulated and subsidized by the government. The idea behind it is that this stimulates the biodiversity and insect population. Usually the edges are not used anyway to have space for machines. Now they are often a bit wider. And certainly more beautiful.
Lovely to see this lovely wide flower border with its colourful variety of flowers - fav! I think that where such flower borders exist here they are about 6ft (1.9 metres) wide, but they are not very common.
What a happy sight! This program reminds me of one that was started by "Lady Bird" Johnson way back in the 1960's when her husband served as president. She had the idea to sow wildflowers in the green dividers of our highways- you can still see many of those "gardens" in bloom today. They are never mowed over, only trimmed.
