A 50-square-metre mosaic of 7,000 plants and flowers, donated by the greenhouse cooperatives of the greater Athens area, were put on display in Kotzia Square, in front of the Athens City Hall, on Sunday, May 1, 2011. May 1, the traditional beginning of Spring, was celebrated around the country on Sunday with lawn & garden shows as well as the collection of wild flowers for the making of floral wreaths, as custom dictates.
