Five years ago, local man Philipp Olsmeyer wanted to makehis Sodermalm area greener and contacted local authorities with his idea for the Tradgard pa Sparet - Swedish for "Garden on track".

"Now there are about 200 (planter) boxes here. Some of them belong to the association and some belong to schools", he said.

A few miles away, Rosendals' Garden is a city farm popular with Stockholm's foodies who enjoy its vegetables, fruits and herbs in the greenhouse café.

Pelle Mattsson combines his job as an illustrator and graphic designer with gardening at Rosendals, something that helps keeps the city-dweller in touch with the changing seasons.

"Gardening in Sweden is season-based so I think it's a good combination," he said. "To sit in the studio and draw and spend a few days in the garden."
